Free agent Grady Sizemore underwent microfracture surgery on his right knee in September, his agent told MLB.com’s Anthony Castrovince on Monday, and he’s expected to be sidelined for at least the first half of next season.
Sizemore already underwent microfracture surgery on his left knee in 2010. The latest procedure would seem to bode particularly ill for his chances of re-emerging as a starting outfielder in the majors.
Sizemore dealt with right knee pain throughout the 2011 and 2012 seasons, and he considered microfracture surgery a year ago before deciding on a less intense procedure that did him little good. He never played a game for the Indians after they re-signed him to a one-year, $5 million contract last winter.
The 30-year-old Sizemore was one of the American League’s best players from 2005-08 before dealing with injuries. He played in 106 games in 2009, 33 in 2010 and 71 in 2011 before missing last season.
