Who is Roki Sasaki? What to know about the Japanese pitching sensation bound for MLB

The latest pitching sensation out of Japan appears bound for Major League Baseball in 2025. 

The Chiba Lotte Marines announced that they have decided to begin the process of posting star pitcher Roki Sasaki, clearing the path for the hard-throwing 23-year-old to transfer from Nippon Professional Baseball to MLB. Sasaki will be subject to international amateur free-agent restrictions, making him available for all 30 teams to sign at a much more modest cost than he would go for on the open market. 

Players who are posted under the age of 25 can only sign a minor-league deal from an MLB club's international bonus pool money. Think more Shohei Ohtani, who was under the same limitations when he signed with the Angels for a paltry $2.3 million in December 2017, than Yoshinobu Yamamoto, who was 25 when he signed with the Dodgers for a record $325 million last offseason. 

While Yamamoto was the more decorated and durable pitcher in NPB, Sasaki is younger, bigger and throws harder. The flamethrower has been on the international radar dating back to his high school days and gained further acclaim in April 2022, when he threw a 19-strikeout perfect game for the Marines at just 20 years old.

Sasaki can light up a radar gun. His fastball has clocked in over 102 mph in Japan and touched 101.9 at the World Baseball Classic, where he sat 100.5 mph and got a bevy of whiffs with his devastating splitter. He was teammates with Yamamoto and Ohtani when Samurai Japan won that 2023 tournament, and there is heavy speculation that he'll team up with them again next year in Los Angeles. The Dodgers are among the clubs who have expressed interest in Sasaki
