Williams gave up four runs (three earned) on three hits Friday, retiring just one batter against the Cardinals.
His small sample size includes 11 earned runs on 18 hits and five walks in 11.2 innings. He's struck out nine batters. Williams compiled a 2.53 ERA in 110.1 innings for Triple-A Indianapolis. A 74:30 K:BB doesn't project great numbers at the major league level, but he could find a spot on Pittsburgh's staff in 2017.
