Shane McClanahan was put on the 15-day injured list by the Tampa Bay Rays on Saturday, a day after the 26-year-old left-hander came out of his second straight start due to mid-back tightness.

McClanahan, 11-1 with a 2.53 ERA, left a June 22 outing against Kansas City after 3⅔ innings and Friday's start against Seattle after three innings. His IL stint will run through the All-Star break.
