Thatcher pitched a scoreless frame and struck out two during the Astros' 7-1 loss to the Rangers on Tuesday. Through 10 relief appearances for the Astros this season, Thatcher has a 2.84 ERA, 1.11 WHIP and 8:1 K:BB over 6.1 innings. Despite solid numbers thus far, he hasn't pitched many high-leverage situations this season, as the Astros have leaned on fellow southpaw Tony Sipp for those occurrences.
