Former Philadelphia Phillies manager Charlie Manuel, who led the club to the 2008 World Series title, suffered a stroke on Saturday.
The club said Manuel, 79, was undergoing a medical procedure in Florida when he had the stroke. Physicians were able to remove a blood clot.
"The next 24 hours will be crucial to his recovery, and Charlie's family asks that you keep him in your thoughts and prayers at this time," the team said in a release.
Manuel finished his managerial career with a 1,000-826 mark, earning 780 of those wins in nine seasons managing the Phillies.
He also went 220-190 as skipper of Cleveland from 2000-02.
Manuel also played six major league seasons and batted .198 with four homers and 43 RBIs in 242 games for the Minnesota Twins (1969-72) and Los Angeles Dodgers (1974-75).
