Stites was recalled from Triple-A Reno on Tuesday, Steve Gilbert of MLB.com reports.
EDGE Analysis
Stites made four appearances for the D-Backs earlier in the season, but he's spent most of his time at Triple-A, where he holds a 4.33 ERA across 27.0 innings. The reliever, who recently returned from a short DL stint, will add depth to the Arizona bullpen down the stretch, but it's unclear whether he'll be trusted in high-leverage situations.
