Bryan Abreu’s diminished velocity on Sunday was the result of a mechanical issue, according to Astros manager Joe Espada.

“We spotted a few things and we’ll be able to get him back on track here for his next outing,” Espada told reporters on Monday. He also confirmed that Abreu isn’t dealing with any physical issues, which is an encouraging development. The 28-year-old high-leverage specialist, who is filling in for injured Astros closer Josh Hader (biceps), averaged just 93.2 mph on his fastball during Sunday’s outing against the Angels in a save situation after averaging 97.3 mph last year. He was ultimately pulled in favor of lefty Bryan King after issuing a pair of walks and recording only one out. It doesn’t sound like the Astros are overly concerned. King would be the clear stash for fantasy managers in the event that Abreu doesn’t turn things around.
