Williams gave up two runs on five hits and two walks over four innings during Saturday's 3-2 win over the Pirates. He had six strikeouts and didn't factor in the decision.
The right-hander surrendered a two-run homer to Ka'ai Tom during the fourth inning, but he otherwise kept Pittsburgh off the board. The Cubs didn't score the game-deciding run until the seventh inning, so he wouldn't have earned the victory even if he lasted the five frames necessary to earn a win. Williams has a 5.81 ERA, 1.74 WHIP and 35:16 K:BB across 31 innings this season.
