Roki Sasaki can sign with Major League Baseball teams during a nine-day window starting Wednesday, an unusual free agency that caused a domino effect among Latin American teenagers whose unofficial agreements are on hold pending his decision. The Los Angeles Dodgers and San Diego Padres are considered the favorites to sign Sasaki, with the Toronto Blue Jays another contender. A prized 23-year-old right-hander, Sasaki could have gotten a nine-figure major league deal if he remained healthy and waited until after the 2026 season to be posted by his Japanese club and join MLB.
