The Astros optioned Kuhnel to Triple-A Sugar Land on Sunday, Matt Kawahara of the Houston Chronicle reports.

EDGE Analysis

Houston will swap Kuhnel out of its bullpen for Parker Mushinski, who was called up from Sugar Land in a corresponding move. After being acquired from the Reds on June 17 before receiving a call-up July 8, Kuhnel gave up four earned runs over two innings in his first two appearances with the Astros.
