White Sox cut struggling shortstop Jimmy Rollins

The Chicago White Sox designated shortstop Jimmy Rollins for assignment and called up top prospect Tim Anderson.

The White Sox purchased Anderson’s contract from triple-A Charlotte on Friday, hoping the shortstop can help jolt a team that has gone from leading the AL Central with a 23-10 record to fourth with a 30-30 record entering this weekend’s series against Kansas City.

The 22-year-old Anderson batted .304 with four home runs and 20 RBIs in 55 games with Charlotte.

Rollins, the 2007 NL MVP, hit .221 in 41 games after signing in late February. The moves come one day after the White Sox designated pitcher Mat Latos for assignment and signed former AL MVP Justin Morneau, who is recovering from left elbow surgery.
