Early Life and Development
Born on November 3, 2001, in Ichihara, Chiba, Japan, Roki Sasaki displayed a passion for baseball at an early age. He began his journey as a pitcher during his high school years and quickly gained recognition for his incredible fastball and poise on the mound. His early promise was evident when he was selected by the Chiba Lotte Marines in the 2019 NPB Draft, which set the stage for his rise to stardom.
Career in Japan’s Professional Baseball League (NPB)
After being drafted by the Chiba Lotte Marines, Sasaki made his NPB debut in 2020, just a year after being selected. From his very first game, it was clear that Sasaki was a special talent. His impressive mechanics and the speed at which he could throw the ball made him stand out in the highly competitive NPB, Japan’s top baseball league.

The Fastest Pitch in Japan
Roki Sasaki’s most distinguishing feature is his fastball. At the age of just 20, Sasaki achieved something that few pitchers in the world ever do — he threw a fastball that reached a blistering 102.5 mph (164 km/h), making him the fastest pitcher in Japan. This remarkable speed quickly garnered attention from scouts and fans alike, as his fastball has become the centerpiece of his pitching arsenal.
His ability to maintain such speed throughout games is something few pitchers can replicate. This consistent velocity, paired with his control and movement, has made Sasaki one of the most feared pitchers in the NPB.
Why Sasaki’s Fastball Stands Out
The speed alone isn’t what makes Sasaki’s fastball so dangerous. His command and location of the pitch are equally impressive. He can throw his fastball precisely where he wants, keeping batters off balance. His fastball speed combined with his secondary pitches, such as his slider and changeup, make him a highly effective and complete pitcher.

Sasaki’s incredible talent and his potential to thrive in MLB could make him one of the best Japanese pitchers to ever step foot on a Major League mound. While his MLB debut is not yet confirmed, speculation around his future in the U.S. is intense.

When Could Sasaki Join MLB?
Although Sasaki’s contract with the Chiba Lotte Marines is currently intact, many are speculating that he may make the move to MLB in the near future. Based on recent trends of young Japanese stars making their way to the MLB, it’s possible that Sasaki could enter the league through the posting system — a process that allows NPB players to be signed by MLB teams. However, the exact timing remains uncertain as Sasaki continues to evolve as a pitcher in Japan.
Roki Sasaki Stats: A Look at His Impressive Numbers
As of 2025, Sasaki’s stats have been nothing short of impressive. His performances on the mound are consistently dominant, with some of his most notable achievements including:

- ERA: Sasaki’s earned run average (ERA) has consistently been below 2.00 in his NPB career, showcasing his ability to keep opposing hitters at bay.

Roki Sasaki vs Shohei Ohtani: A Friendly Rivalry
Two of Japan’s Best Baseball Talents
The comparison between Roki Sasaki and Shohei Ohtani is inevitable. Both are incredibly talented pitchers from Japan, but each has a unique style that sets them apart. Ohtani’s dual-threat status, excelling as both a pitcher and a hitter in MLB, is unmatched. Meanwhile, Sasaki’s focus is primarily on his dominant pitching.
The question remains: Could Sasaki one day join Ohtani in MLB and perhaps even become a rival? Given Sasaki’s fastball speed and overall potential, the two Japanese superstars could make a powerful duo in MLB, each bringing their unique flair to the game.
Will Sasaki Ever Reach Ohtani’s Level?
Many believe that Roki Sasaki has the potential to be just as impactful in MLB as Shohei Ohtani. However, the road to becoming an international MLB sensation is challenging, and it will require Sasaki to continue honing his skills, especially his command and mental toughness under pressure.
