Diamondbacks' Matt Koch: Sent to Triple-A

Koch was optioned to Triple-A Reno on Monday.

Koch was hampered by a hamstring injury for much of spring training, allowing him to register only four innings in three appearances during camp. Although he pitched well in his appearances this spring, the extended absence left him destined for Triple-A to start the season, where he'll be one of the Diamondbacks' top options when a spot starter is needed.
