ARLINGTON, Texas (AP) Texas Rangers third baseman Hank Blalock has a small tear in his left hamstring and will be out at least three weeks.

Blalock had an MRI on Monday, followed by an injection. The two-time All-Star hurt himself running out a double Friday night and hasn't played since.

The Rangers, who were off Monday, will put Blalock on the 15-day disabled list before they resume their six-game homestand against Kansas City on Tuesday night.

Shortstop Michael Young has a sore calf, but manager Ron Washington has said Young's problem isn't serious. Young came out of Sunday's game after the sixth inning, when the Rangers led 9-0, to get some extra rest.

Blalock is hitting .299 with three home runs and seven RBIs. After the double in the 10th inning Friday night against Minnesota, Blalock was replaced by pinch-runner German Duran, who scored the game-winning run in a 6-5 victory that snapped the Rangers' seven-game losing streak.

Last season, Blalock was limited to 58 games after having surgery in May to remove a rib that affected nerves in his throwing shoulder.

Blalock returned to the lineup in September, but only as a designated hitter for the rest of the season. That's the only other time in his seven major league seasons he has been on the DL.
