Wacha (2-3) gave up four runs on six hits and two walks over six innings while striking out six to take the loss in Sunday's 10-5 defeat at the hands of the Pirates.
He's now lost three straight starts, but Wacha's 3.12 ERA, 1.27 WHIP and 38:14 K:BB in 43.1 innings remain solid. He'll try to get back in the win column Saturday, on the road against the Dodgers.
