Diamondbacks' Joe Mantiply: Sent down to Reno

The Diamondbacks optioned Mantiply to Triple-A Reno on Saturday.

Mantiply has struggled mightily in the big leagues this season, giving up 13 earned runs in just 7.1 innings. He'll attempt to get back on track in Triple-A, though the D-backs may want to see him sustain success for an extended period of time before inserting him back into their bullpen.
