Troy Tulowitzki to have groin surgery
PHILADELPHIA (AP) Colorado Rockies shortstop Troy Tulowitzki will have surgery on his left groin area on Thursday and it's unknown when he'll return.
Tulowitzki was injured May 30 against Houston, pulling up after running out an infield grounder. The All-Star shortstop took himself out of a game last Wednesday at Triple-A Colorado Springs after feeling not quite right.
Rockies manager Jim Tracy says a timetable for Tulowitzki's return won't be known until he has the surgery. The operation will be performed by Dr. William Meyers in Philadelphia.
Tulowitzki has won the Gold Glove, Silver Slugger Award and gone to the All-Star game each of the last two years. He was batting .287 with eight homers and 27 RBIs.
