Mookie Betts' move to the Dodgers was held up on Wednesday after the Red Sox raised medical concerns about pitching prospect Brusdar Graterol, according to ESPN's Jeff Passan.
Betts was traded from Boston to Los Angeles on Tuesday in a three-team deal. The Dodgers were slated to receive Betts and starting pitcher David Price, and the Minnesota Twins were to receive starting pitcher Kenta Maeda. Graterol joined outfielder Alex Verdugo in the return to Boston, though his physical is reportedly freezing the deal.
"The Red Sox, sources said, were spooked by a medical review of Graterol, the hard-throwing 21-year-old right-hander who has undergone Tommy John surgery and missed time in 2019 because of a shoulder injury," Passan wrote on Wednesday night.
