Sendai University right-hander Genei Sato is reportedly set to transfer to a university in the United States next year as he pursues a faster entry to Major League Baseball. He will be ineligible for the 2026 college season, but is expected to compete in a summer league before playing in the 2027 NCAA season, after which he plans to declare for the MLB Draft in July.

Sato, who turns 21 this week, was widely regarded as the No. 1 prospect in the 2026 Nippon Professional Baseball Draft pool. He impressed against Team USA at the Collegiate All-Star Series in July, topping out at 99 mph on his four-seam fastball and striking out top American prospects like Roch Cholowsky and Drew Burress.
“He’s real,” Cholowsky told Baseball America. “I faced him twice. First-pitch fastball hit to the wall in center in the first at-bat, and then he blew my doors in.”
The Aomori native also throws a hard splitter that regularly reaches over 90 mph, along with a mid-80s slider and low-70s curveball. Had the 5-foot-11, 180-pounder elected to play in NPB, he would have instantly featured one of the league’s best fastball-splitter combinations and possessed true ace upside.
During his collegiate career, Sato has posted a 2.22 ERA with 202 strikeouts and 63 walks over 170 1/3 innings, with appearances as both a starter and reliever, according to Japanese outlet Draft-Repo. 2025 was his junior year at the Miyagi-based university.
Sato is the latest in a growing wave of Japanese amateurs opting to head to the United States rather than begin their careers in NPB. MLB’s international amateur bonus pool restrictions, NPB’s lengthy service time requirements for international free agency, and the current posting system structure have all contributed to pushing top talents toward what is still widely viewed as a risky path.
Huge MLB Draft ramifications here in 2027.
Genei Sato is coming to the United States. He will pitch this summer in the U.S. and play college ball in 2027. Turns 21 years old on Wednesday. Will be 22.5 years old for 2027 Draft.

Most notably, Itsuki Takemoto and Rintaro Sasaki enrolled at American colleges out of high school, while Shotaro Morii signed directly with the Athletics as an international amateur free agent.
Sasaki, entering his sophomore year at Stanford, remains the highest-profile Japanese prospect ever to forgo the NPB Draft. However, NPB recently changed its draft eligibility rules to allow him to be selected anyway, and he was drafted by the SoftBank Hawks in October. He remains eligible for the MLB Draft next July, when he will ultimately decide whether to return to Japan to begin his professional career or to join an MLB organization, as he had originally hoped.
Sato is taking a slightly different route than the others, transferring out of a Japanese university in his final year to become eligible for the MLB Draft. While the move itself is not completely unprecedented for a Japanese amateur, no amateur before has ever matched Sato’s prospect pedigree or made such a deliberate push toward becoming a top MLB Draft pick.
