Topa (elbow) was reinstated from the 60-day injured list Wednesday.
Topa began the season on the 60-day injured list due to a flexor tendon strain, and he spent nearly a month in the minors on a rehab assignment. Across 10 relief appearances, the right-hander posted a 2.00 ERA and 1.00 WHIP in nine innings. He'll now be available to make his season debut out of Milwaukee's bullpen.
