Diamondbacks' Andrew Saalfrank: Sent down to Triple-A

The Diamondbacks optioned Saalfrank to Triple-A Reno on Friday.

Saalfrank had a key role down the stretch for the Diamondbacks last season, but he had minor-league options remaining and that might have worked against him. The southpaw will likely to spend plenty of time in Arizona's bullpen this season.
