Brewers' Angel Perdomo: Placed on injured list

Perdomo was placed on the 10-day injured list Wednesday with a strain in his lower back.

The left-hander pitched during Tuesday's doubleheader and struggled, giving up a run on a hit and three walks while recording two strikeouts in two-thirds of an inning. The severity of the injury is unknown, and Perdomo will be eligible to return Aug. 21.
