Cubs placed LHP Caleb Thielbar on the 15-day injured list with a left hamstring strain.

The 39-year-old hurler suffered the injury during the ninth inning of Thursday’s outing against the Phillies. It’s an unfortunate break for Thielbar — and fantasy managers — as he had ascended to the closer’s role following the injury to Daniel Palencia. No word yet on how much time he’ll miss. Vince Velasquez was promoted from Triple-A Iowa to take his place in the Cubs’ bullpen.
