Rintaro Sasaki to sign with Miami Marlins, bypassing Japan pro path

Rintaro Sasaki planned to sign with the Miami Marlins after the club took the Stanford slugger in the eighth round of the 2026 MLB Draft, making him the No. 235 overall pick. The move sends one of Japan’s most closely watched young hitters into a U.S. organization instead of the traditional Nippon Professional Baseball pipeline.

Sasaki’s decision was striking because he had been expected to go first overall in the NPB draft before choosing Stanford. MLB coverage had already cast him as a Japanese high school home-run king and a power-hitting prodigy, and his path only sharpened that reputation once he arrived in the United States. MLB later reported that Sasaki announced his plan to sign with Miami via social media.

The 6-foot-1, 270-pound batter, who throws right-handed and hits left-handed, was born April 18, 2005. He first drew major attention in the U.S. Draft League, where MLB reported that he homered in his debut. At the 2026 Draft Combine, he posted the session’s highest exit velocity at 115.4 mph and hit two of the four longest home runs measured there, including drives of 458 feet and 434 feet.

For the Marlins, the signing adds a high-upside bat with international name recognition and a profile that fits a long-development gamble. Miami has spent years operating in a market where talent evaluation and player growth matter as much as payroll, and Sasaki’s arrival fits an organization looking for ceiling. Stanford Athletics said four Cardinal were selected in the 2026 MLB Draft, with Sasaki among the most prominent names in that group.

Sasaki’s route is still unusual, but it is not random. Elite players from Japan have long reached the majors, yet the stages are shifting: some now choose college baseball in the United States, enter the draft, and sign with an MLB club before ever playing professionally at home. That makes Sasaki less a one-off than an early sign of how aggressively MLB teams are pulling at top international talent while those players are still at the start of their careers.
