The Rangers designated Patton for assignment Thursday.

EDGE Analysis

Patton lost his spot on the 40-man roster to outfielder Steven Duggar (oblique), whom the Rangers acquired from the Giants on Thursday and then activated from the 60-day injured list. Since being activated from the injured list May 11 and getting optioned to Triple-A Round Rock, Patton produced a 3.86 ERA and 1.61 WHIP over 9.1 innings out of the bullpen for the Rangers' top affiliate.
