Diamondbacks' Stefan Crichton: Summoned to majors

Crichton was recalled from Triple-A Reno on Wednesday.

Crichton spent time with the Diamondbacks earlier in the season, making four appearances out of the bullpen and allowing just one hit while striking out three across 2.2 scoreless innings. He'll take the roster spot of Jon Duplantier (shoulder), who was sent to the injured list in a corresponding move Wednesday.
