Caleb Thielbar Activated Off Injured List, Returns To Cubs' Bullpen

The Chicago Cubs are getting an important piece of their bullpen back.

Left-handed reliever Caleb Thielbar was activated from the 15-day injured list Tuesday by the Cubs. Left-handed reliever Ty Blach was designated for assignment after making his team debut Monday.

Thielbar has been on the injured list since April 24 with a strained left hamstring. He made one rehab appearance with High-A South Bend over the weekend, pitching one scoreless inning with a hit, a walk and two strikeouts. With the Cubs, Thielbar has made 11 appearances covering 8⅔ innings, walking five and striking out 11.

Blach pitched three scoreless innings in Monday's 9-3 blowout loss to the Milwaukee Brewers, allowing one hit and no walks with two strikeouts.
