The Chicago Cubs have placed left-hander Caleb Thielbar on the 15-day injured list with a left hamstring strain. The Cubs also transferred right-hander Porter Hodge to the 60-day injured list while infielder Scott Kingery was designated for assignment. Chicago selected the contracts of infielder Nicky Lopez and right-hander Vince Velasquez from Triple-A Iowa. Thielbar is 2-2 with two saves and a 3.12 ERA in 11 appearances. He left Thursday's game against Philadelphia after facing just one batter. Hodge is recovering from Tommy John surgery after originally being placed on the injured list with a right elbow strain on March 22.
