MINNEAPOLIS -- Torii Hunter celebrated his 32nd birthday on Wednesday, but it wasn't exactly a day to remember for him on the field.
Hunter left the game vs. the Tigers in the fourth inning after grounding into a fielder's choice. Hunter aggravated his left hamstring while running to first base. He was diagnosed with a mild strain and is listed as day-to-day.
It's the same hamstring that has been bothering Hunter and caused him to sit out Sunday's game vs. Oakland.
After beating out the throw to first by Tigers second baseman Placido Polanco, Hunter reached for the back of his left leg. A few attempts to walk off the injury did nothing, and caused trainer Rick McWane and manager Ron Gardenhire to go out on the field. Hunter then exited the field with the two.
Jason Kubel pinch-ran for Hunter in the inning and remained in the game in left field. Lew Ford moved from left field to center field.
