Twins' Caleb Thielbar: Goes on IL

The Twins placed Thielbar (hamstring) on the 15-day injured list Thursday.

Thielbar is one of six Twins relievers that will begin the season on the injured list. He's eligible for activation April 9, but since he didn't pitch in any Grapefruit League games while recovering from the left hamstring strain, Thielbar may need more than the minimum 15 days to complete his recovery before being ready to join Minnesota.
