Bummer (0-4) allowed three runs on two hits, a walk and a wild pitch to pick up the loss against the Blue Jays on Wednesday.
Bummer entered a clean eighth inning after Lance Lynn cruised through seven innings of one-run ball. After getting the first out, Bummer struck out Riley Adams on a pitch in a dirt that got by catcher Yasmani Grandal. That was followed by an infield hit, a single and a botched double play, and the White Sox were down 4-2. The right-hander has given up runs in six of his last nine outings, allowing 10 runs (nine earned) over 7.2 innings.
