Pfaadt (9-8) took the loss Friday, giving up four runs on eight hits and two walks over 4.2 innings as the Diamondbacks were downed 8-0 by the Astros. He struck out five.
Half the hits off the right-hander went for extra bases, including a three-run homer by Yordan Alvarez in the fifth inning. Pfaadt hasn't been able to complete six innings in any of his last four starts, stumbling to a 7.52 ERA, 1.97 WHIP over that stretch despite a 25:7 K:BB in 20.1 innings. He'll try to get back on track in his next outing, which lines up to come at home next weekend against the Brewers.
