The Brewers continued to tinker with their bullpen as they purchased the contract of relief pitcher Wei-Chung Wang from AAA Colorado Springs.  The team already had an open spot on their 40-man roster, but needed to free up a spot on the 25-man squad and they did so by optioning Opening Day starter Junior Guerra to Colorado Springs.

Wang, who last pitched in the big leagues in 2014, when the Brewers selected him from the Pittsburgh Pirates in the Rule 5 Draft, has worked his way through Milwaukee’s minor league system since then, and had turned into a valuable left-handed contributor out of the Sky Sox bullpen.

In 39 relief appearances this season, the 25-year-old Wang, went 5-1 with a 2.09 earned run average, and provides Milwaukee with another lefty to turn to in their bullpen.

Guerra, who has battled injuries and inconsistency all season long, lasted just three innings in his most recent start for the Brewers on Saturday night.  In 13 starts for Milwaukee this season, Guerra had a record of 1-4 with a 4.96 earned run average and a WHIP of 1.28.

He’ll head to Colorado Springs in hopes that he can figure it out and come back to help down the stretch, but with Chase Anderson and Matt Garza on the shelf, and Guerra’s demotion, the Brewers have a lot of questions in their starting rotation as they head towards the final two months of the season.
