Astros' Jandel Gustave: Suffering from recurring arm soreness

Gustave was sent back to Houston to see team doctors after dealing with recurring arm soreness at Triple-A Fresno, Brian McTaggart of MLB.com reports.

Gustave had been working his way towards a rehab assignment after dealing with forearm tightness in April. That's always a scary diagnosis for pitchers, given how often it is the precursor to Tommy John surgery. Hopefully Houston's team doctors will come up with a better prognosis. Either way, Gustave's return will be delayed, as he will still need to go on a rehab assignment even if everything checks out fine.
