Shotaro Morii (森井翔太郎, Morii Shōtarō; born December 15, 2006) is a Japanese professional baseball infielder and pitcher in the Athletics organization.[1]

Amateur career

Morii attended Toho High School in Kunitachi, Tokyo, where he hit 45 home runs in his high school career and recorded a top pitch speed of 153 km/h (95 mph).[2]

Professional career

Although he was considered one of the top prospects for the 2024 NPB draft, Morii chose to forgo the draft in order to sign with a Major League Baseball organization.[3][2] On January 15, 2025, Morii signed with the Athletics for a $1,510,500 signing bonus, the largest ever given by an MLB team to a Japanese amateur position player.[4][5]

Morii made his pitching debut for the Single-A Stockton Ports on May 14, 2026, throwing a scoreless inning.[6]
