Roki Sasaki the Dodgers: The Los Angeles Dodgers didn’t need to make an official announcement. They didn’t need to put it on the lineup card or explain it in a press conference. Anyone who watched Game 2 of the National League Wild Card Series against the Cincinnati Reds on October 1, 2025, saw the truth with their own eyes: Roki Sasaki is the Dodgers’ closer.
Sure, manager Dave Roberts was careful with his words, and president of baseball operations Andrew Friedman spoke in cautious executive-speak. They talked about “leverage innings” and “important outs,” avoiding the word closer as if it carried too much weight. But come on we all saw what happened. Sasaki stepped on the mound in the ninth inning, unleashed a barrage of triple-digit fastballs, and slammed the door shut.
For a Dodgers team that had been plagued by bullpen uncertainty all season, this was a revelation. Their Achilles’ heel instantly turned into a weapon. It wasn’t just that Sasaki got the outs it was how he got them. Pure dominance, no hesitation, no fear.
Fans at Dodger Stadium recognized it right away. After just two pitches, chants of “Roki! Roki!” filled the air. The usually cynical and restless LA crowd turned into a sea of believers, united by the sight of a 23-year-old Japanese rookie throwing gas like a man possessed.
In the span of 11 pitches, the Dodgers’ postseason outlook changed. The bullpen, once the biggest question mark, suddenly had an answer. The Dodgers had found their ninth-inning weapon, and his name is Roki Sasaki.
Roki Sasaki’s Journey to the Dodgers
To understand why Sasaki’s appearance was so electrifying, you have to know his backstory. He wasn’t just another prospect who worked his way up through the minor leagues. Sasaki arrived in MLB with a reputation that bordered on mythical.
Back in Japan, with the Chiba Lotte Marines, Sasaki built his legend with jaw-dropping performances that made international headlines. None was bigger than his historic game in April 2022, when he struck out 19 batters in a perfect game. Think about that: not only did he retire all 27 hitters he faced, but he also fanned 19 of them. It was the most dominant pitching performance in professional baseball history, and he did it at age 20.
Japanese fans called him The Monster a nickname that captured both his size (6-foot-4 with a powerful frame) and his otherworldly stuff. MLB scouts had been drooling over him since his teenage years, but Japanese baseball’s posting system meant he had to wait until his early 20s to make the jump across the Pacific.
When Sasaki finally became available, the Dodgers were ready. Already armed with Shohei Ohtani and Yoshinobu Yamamoto, they went all-in to secure a third Japanese superstar. The signing wasn’t just about baseball it was about building an international empire. With Sasaki, the Dodgers added not only an ace-caliber pitcher but also another bridge to Japan’s massive baseball audience.
Still, even with his reputation, no one knew exactly how Sasaki would transition to MLB. Pitchers from Nippon Professional Baseball (NPB) often face an adjustment period with the tighter baseballs, different mound, and relentless travel schedule. But Sasaki had two things that don’t require adjustment: velocity and fearlessness. Those translate anywhere.
And now, in October 2025, we’re seeing the payoff. The same kid who grew up throwing on the beaches of Iwate Prefecture in rural Japan is closing playoff games for the Los Angeles Dodgers. It’s the stuff of movies.
The Dodgers’ Bullpen Crisis in 2025
Before Sasaki stepped in, the Dodgers’ bullpen situation was a mess. In fact, many analysts thought it was their fatal flaw heading into the postseason.
Throughout the regular season, the Dodgers experimented with different closing options. Tanner Scott, who had been acquired with hopes of stabilizing the ninth inning, never found consistency. Converted starter Emmet Sheehan showed flashes but also melted down in high-leverage spots. Young arms like Edgardo Henriquez and Jack Dreyer weren’t ready for the pressure.
By the time the playoffs arrived, Roberts had no clear answer. In Game 1 against the Reds, the bullpen nearly imploded. With a comfortable lead, the Dodgers’ relievers let Cincinnati back into the game in the eighth inning, surrendering three runs. Although LA escaped with a win, it was a red flag.
Game 2 wasn’t much better at least until Sasaki entered. Once again, the bullpen faltered in the eighth. Sheehan faced five batters and retired only one of them. The Dodgers’ 8–2 lead shrank to 8–4, and the crowd started to get that all-too-familiar sense of dread.
Enter Sasaki. As soon as he started warming up, the energy shifted. Fans rose to their feet, teammates perked up, and the Reds looked uneasy. It wasn’t just another reliever jogging in from the bullpen it was the Dodgers’ secret weapon, the one piece of their roster they hadn’t fully unveiled yet.
In many ways, Sasaki became the closer by default. Every other option had failed. But as we would soon see, he wasn’t just the last resort he was the best possible answer.
The Wild Card Series Sasaki’s Defining Moment
Picture this: It’s the bottom of the eighth inning at Dodger Stadium. The Dodgers are clinging to an 8–4 lead. The bullpen has just coughed up two runs, and Cincinnati’s dugout is buzzing with life. The Dodgers’ postseason dream suddenly feels fragile.
Then, the bullpen door swings open, and Roki Sasaki emerges. The crowd roars. After two years of hype and anticipation, he’s finally stepping into a true October moment.
What followed was 11 pitches of pure dominance. Sasaki threw seven fastballs, six of them clocked at over 100 mph. The “slow” one registered at 99.8. On top of that, he mixed in his trademark forkball, a pitch that drops so sharply it looks like it’s falling off a cliff.
The results were devastating. Spencer Steer and Gavin Lux had no chance. Sasaki blew them away with ease, striking both out. The final batter, Stuart Fairchild, made weak contact and grounded out, sealing the win.
The crowd chanted his name. His teammates, like Max Muncy, were left speechless. “Really, all you can say is wow,” Muncy said afterward.
What made it so special wasn’t just the velocity. It was the composure. Sasaki looked completely unfazed by the pressure, as if closing out a playoff game in front of 50,000 fans was just another day at the office.
In a single inning, Sasaki didn’t just earn a save he earned the trust of an entire organization.
The Stuff That Makes Sasaki Special
What separates Sasaki from other pitchers isn’t just one pitch it’s the combination of multiple elite weapons.
First, there’s the fastball. Triple-digit velocity is rare, but sustaining it consistently, pitch after pitch, is almost unheard of. Sasaki doesn’t just touch 100 mph; he lives there. His delivery is fluid and efficient, which makes the velocity even more shocking because it looks effortless.
Then there’s the forkball. If the fastball is the hammer, the forkball is the dagger. It drops off the table so suddenly that hitters can’t adjust. One second it looks like a strike, the next it’s bouncing in the dirt. Many compare it to a split-finger fastball, but Sasaki’s has an extra level of depth and late movement that makes it nearly unhittable.
Combine those two, and you get an unfair advantage. Hitters who gear up for 100 mph heat are helpless against the forkball. Hitters who expect the forkball are late on the fastball. It’s a nightmare situation.
Analysts have already started comparing him to the greats. His overpowering velocity recalls Aroldis Chapman in his prime. His devastating out pitch evokes Mariano Rivera’s cutter. And his crossover appeal, especially as a young Japanese star, puts him in the same conversation as Shohei Ohtani.
What makes it even scarier? He’s just 23 years old. This isn’t his peak this is just the beginning.
Is Sasaki Officially the Dodgers’ Closer?
Here’s the funny part: the Dodgers won’t outright say it. Manager Dave Roberts, who’s known for his diplomatic style, chose his words carefully after Game 2 against the Reds. “I trust him,” Roberts said, “and he’s going to pitch in leverage.”
That’s baseball-speak for: Yes, he’s the closer, but I’m not about to label him just yet.
President of baseball operations Andrew Friedman wasn’t much clearer. When asked if Sasaki had taken the role, Friedman replied, “He’s going to get important outs for us.” Again, it’s not exactly a denial.
But let’s be honest this is one of those situations where actions speak louder than words. You don’t call on a 23-year-old rookie to protect a four-run lead in the ninth inning of a playoff game unless you believe he’s the guy. You don’t let him throw seven consecutive fastballs over 100 mph and walk away pretending he’s just another option.
The Dodgers may hesitate to give him the title officially because they don’t want to put unnecessary pressure on him. They’ve seen young pitchers burn out when thrown into high-leverage roles too quickly. But in reality, Sasaki’s performance left no room for debate.
The Dodgers don’t just need him to be the closer. He is the closer. Everyone in the clubhouse knows it, every fan chanting his name knows it, and every hitter who steps into the box against him knows it.
What’s most striking is how quickly he assumed that role. Roki Sasaki wasn’t supposed to be in this position. He was brought over as a starter, a long-term ace who could headline rotations alongside Yoshinobu Yamamoto. But baseball has a way of creating unexpected heroes. In October 2025, the Dodgers found theirs in the ninth inning.
Historical Context Legendary Rookie Closers
If Sasaki does indeed step into the closer’s role for the Dodgers’ postseason run, he won’t be the first rookie to seize October and refuse to let go. Baseball history is filled with stories of unlikely relievers turning into October legends.
Take Francisco Rodríguez, for example. In 2002, “K-Rod” burst onto the scene for the Anaheim Angels. At just 20 years old, he became the most dominant pitcher in the postseason, striking out hitters left and right with his electric fastball and slider. The Angels rode his arm all the way to a World Series title.
Or think of David Price with the Tampa Bay Rays in 2008. Just months removed from Vanderbilt University, he was suddenly pitching in the biggest games of his life and thriving. His performance in the ALCS helped carry the Rays to their first-ever World Series appearance.
Even Aroldis Chapman, though not a rookie, made headlines when he arrived in MLB throwing harder than anyone had ever seen before. The buzz around his triple-digit fastball mirrors the excitement surrounding Sasaki today.
Sasaki fits squarely into this tradition. Like Rodríguez and Price, he’s young, fearless, and utterly unhittable when his stuff is working. Like Chapman, he has a fastball that defies belief. The difference? Sasaki also brings with him the aura of having already been a legend in Japan before stepping foot in the majors.
If the Dodgers go deep into October, Sasaki could very well etch his name alongside these rookie sensations and maybe even surpass them.
What This Means for the Dodgers Moving Forward
The timing of Sasaki’s emergence couldn’t be better. The Dodgers’ reward for sweeping the Reds is a clash with the Philadelphia Phillies, a team loaded with left-handed power. Kyle Schwarber, Bryce Harper, and Juan Soto form one of the scariest lineups in baseball. To beat them, the Dodgers will need a shutdown arm in the late innings.
Enter Sasaki.
His fastball-forkball combo is particularly deadly against lefties. The forkball dives away from their bats, while the fastball overwhelms them with speed they can barely register. If there’s a pitcher built to neutralize Philadelphia’s sluggers, it’s him.
But there’s more than just the numbers at play. Baseball is as much mental as it is physical. When a team knows it has a closer who can end games without hesitation, it changes everything. Starters feel less pressure to go deep into games. Relievers in earlier innings can focus on bridging the gap. And hitters relax, knowing one mistake late won’t cost them everything.
In short, Sasaki’s presence gives the Dodgers confidence. It erases the cloud of uncertainty that has hung over their bullpen all season.
Of course, one inning doesn’t guarantee postseason glory. October baseball has a way of humbling even the brightest stars. But right now, Sasaki looks like the X-factor the Dodgers desperately needed the final piece of the puzzle in their chase for another World Series title.
Fan and Media Reaction
If there was any doubt about how Sasaki’s performance resonated, just listen to the reactions.
Third baseman Max Muncy summed it up in one word: “Wow.” Teammates who’ve seen countless pitchers come and go were left speechless. Catcher Ben Rortvedt put it simply: “You guys saw the same thing I did.”
Fans, meanwhile, went crazy. Dodger Stadium, often criticized for its late-arriving crowds and early exits, transformed into a thunderous arena. Chants of “Roki! Roki!” echoed through Chavez Ravine after just two pitches. That’s how quickly he won them over.
The Japanese media was just as captivated. Sasaki’s debut was broadcast live back home, where millions tuned in to watch their young phenom pitch in the MLB postseason for the first time. Social media exploded with comparisons to Shohei Ohtani’s early days with the Angels and to Sasaki’s own legendary performances in Japan.
Even the usually skeptical Los Angeles press corps had no choice but to buy in. Columnists who were preparing to write about the Dodgers’ bullpen implosion suddenly had to shift gears, instead describing the arrival of a new star.
In a city that’s already buzzing about Ohtani’s bat and Yamamoto’s arm, Sasaki added another layer of excitement. He wasn’t just another pitcher he was the story of the night, the player who stole the spotlight when it mattered most.
The Business Side of Sasaki’s Stardom
Make no mistake: Sasaki’s dominance isn’t just a baseball story. It’s also a business story.
The Dodgers already boast the most global brand in Major League Baseball. With Ohtani, Yamamoto, and now Sasaki, they’ve essentially cornered the Japanese market. Their games draw massive viewership in Japan, their merchandise sells worldwide, and Dodger Stadium has become a pilgrimage site for international fans.
Sasaki’s arrival amplifies that. Imagine the marketing power of Ohtani at the plate, Yamamoto in the rotation, and Sasaki closing games. It’s a trio unlike anything baseball has ever seen.
For the Dodgers, this isn’t just about winning games it’s about building an empire. Every time Sasaki takes the mound, he’s not just representing the team; he’s representing a bridge between two baseball cultures. And the financial impact is enormous.
Ticket sales, jersey sales, TV ratings, sponsorships everything spikes when stars like Sasaki thrive. The Dodgers aren’t just a team anymore; they’re an international phenomenon. And Sasaki, with his overpowering stuff and magnetic presence, might just be the final piece that makes them unstoppable both on and off the field.
The Big Picture A Star is Born
Every October, baseball introduces us to new heroes. Some fade after their moment in the spotlight, while others build dynasties on that foundation. Roki Sasaki looks like the latter.
What makes Sasaki’s story different from other relievers is that his ceiling isn’t limited to the bullpen. The Dodgers didn’t bring him across the Pacific just to be a closer. He was signed as a future ace someone who could anchor a rotation for years. His fastball-forkball combo is elite, but scouts will tell you he also has the command and secondary pitches to dominate over seven innings, not just one.
So what does that mean for the Dodgers? Right now, they’re in win-now mode. With Ohtani, Mookie Betts, Freddie Freeman, and Yamamoto, their championship window is wide open. If Sasaki is best used in the ninth inning to secure that window, then that’s where he’ll stay at least for this October.
But beyond 2025, the possibilities are tantalizing. Imagine a rotation led by Sasaki and Yamamoto, with Ohtani healthy enough to contribute on the mound as well. That’s not just good that’s potentially historic.
For now, though, the Dodgers don’t need him to be the next Clayton Kershaw. They need him to be the final nail in the coffin for opposing lineups. And based on what we’ve seen, he’s more than capable of doing just that.
This is the beauty of baseball: sometimes a player arrives not just with talent, but with timing. Sasaki didn’t just show up he showed up when the Dodgers needed him most. And in doing so, he may have changed the trajectory of their season.
Conclusion
Roki Sasaki’s postseason debut was more than just an impressive inning it was a statement. The Dodgers, who had spent the entire season searching for stability in the bullpen, found their answer in the most dramatic way possible.
The team may not call him the closer yet, but let’s not kid ourselves: he’s the closer. His 100 mph fastball, his devastating forkball, and his unshakable composure under the lights make him the obvious choice. One inning was enough to flip the narrative from “Can the Dodgers survive their bullpen?” to “Can anyone survive Sasaki?”
In baseball, moments define legacies. Francisco Rodríguez had 2002. David Price had 2008. Now, Roki Sasaki has 2025. And if the Dodgers go on to make a deep October run, his name will be remembered not just as part of the team, but as the reason the team found its identity.
The Dodgers have plenty of stars, but in Game 2 of the Wild Card Series, a new one was born. His name is Roki Sasaki and he’s here to close.
FAQs
1. Why did the Dodgers move Sasaki to the bullpen?
The Dodgers originally planned for Sasaki to be a starter, but bullpen struggles forced them to use him in relief late in the season. His velocity and ability to handle pressure made him a natural fit for the closer role.
2. Has Sasaki ever closed games in Japan?
No. During his time with the Chiba Lotte Marines, Sasaki was a starting pitcher. He had never pitched in relief until a brief rehab assignment and his late-season appearances with the Dodgers.
3. How fast is Sasaki’s fastball compared to MLB leaders?
Sasaki consistently throws over 100 mph, putting him among the hardest throwers in MLB. His average velocity in his postseason debut was higher than nearly every established closer in the league.
4. Who are the Dodgers’ other closing options besides Sasaki?
Before Sasaki’s emergence, the Dodgers tried Tanner Scott, Emmet Sheehan, and other relievers in late-inning roles. None of them performed consistently, which opened the door for Sasaki to take over.
5. Could Sasaki return to the starting rotation in the future?
Yes. The Dodgers still view Sasaki as a potential long-term ace. While he may serve as the closer this postseason, he could shift back into a starting role as soon as 2026.
