The Houston Astros are officially activating their star closer, Josh Hader, off the 60-day injured list.
The 32-year-old was diagnosed with left bicep tendinitis and has yet to make his debut this season. The injury occurred during an offseason workout session prior to spring training.
During the bullpen session, while throwing a changeup, he was experiencing discomfort (inflammation), which had him miss the start of the season.
Hader made his ninth minor league rehab start on May 28 with Triple-A Sugar Land and pitched one inning, allowing two runs (zero earned).
