The Pittsburgh Pirates will be without Oneil Cruz for at least four months after the shortstop had surgery late Sunday to repair a fractured left ankle.

Cruz's left leg bent awkwardly underneath him as he tried to score from third on a chopper in the sixth inning of Sunday's 1-0 victory over the Chicago White Sox.

The Pirates believe Cruz will be able to return by mid-August, but Derek Shelton stressed he's more concerned about Cruz's health and state of mind. Shelton added that there was a "sense of relief" that the injury wasn't worse.

"My solace is in the fact that he's OK," Shelton said.

The 6-foot-7 Cruz was hitting .250/.375/.375 with one home run and four RBI through nine games.
