White Sox prospect Keenyn Walker has surgery on his shoulder and knee

Yesterday, White Sox prospect OF Keenyn Walker underwent surgery on his right knee and left shoulder in Chicago. On Twitter, the 2011 first supplemental round pick said the surgery "went well" and that he would be back in 3 to 4 months. The length of the recovery is due to the rehab time for the more serious shoulder surgery. He also tweeted a photo of his post-surgery shoulder.

The 22 year old spent almost three weeks during June on the disabled list because of his right knee after suffering a partially torn meniscus and bone bruise in a collision at first base. Walker, who throws right-handed, injured his left shoulder in late July on an awkward slide to avoid a tag at home plate and spent a week on the disabled list immediately after the injury. Each of these injuries nagged Walker for the rest of the season.

Despite these injuries, his 2012 season was a successful one with the raw center fielder improving his game across the board. Between Kannapolis and Winston-Salem, Walker put up a triple slash of .267/.378/.379 and was 56 for 71 in stolen bases. The switch-hitter will need to work on his strikeout rate in 2013, however, as his 29.5% rate is too high for a player with his limited power.
