Diamondbacks' Andrew Chafin: Being used on situational basis

Chafin retired the only batter he faced in Wednesday's 8-2 win over the Rockies.

Chafin has been utilized as a setup man for much of the season, but the July 31 acquisition of David Hernandez along with the late-summer promotion of Jimmie Sherfy has resulted in manager Torey Lovullo tinkering with Chafin's role. The right-hander looks like he'll be used mostly as a situational pitcher going forward, a luxury afforded to the Diamondbacks due to their deeper bullpen with the expanded rosters. Chafin has been asked to record no more than two outs in any of his last six appearances.
