The Rangers selected Dunning's contract from Triple-A Round Rock on Monday.

EDGE Analysis

Dunning will be available out of the bullpen for Monday's series opener in Baltimore, but if he goes unused, he'll be an option to make a spot start or serve as a bulk reliever in Tuesday's contest. Since being outrighted off the Rangers' 40-man roster in May, Dunning has been working out of the rotation at Round Rock, pitching to a 3.76 ERA, 1.06 WHIP and 28:9 K:BB in 26.1 innings. Even if he ends up getting a start Tuesday, Dunning likely won't be in store for multiple turns through the rotation since Nathan Eovaldi (triceps) looks poised to return from the 15-day injured list later this week.
