Bummer (0-1) recorded the loss Thursday, allowing three runs on a hit and two walks with two strikeouts over 1.2 innings in a 5-2 extra-inning loss to the Royals.
The southpaw is part of the high-leverage mix for the White Sox, and with Liam Hendriks (back) unavailable, Bummer got the call in a tie game in the top of the 10th. He couldn't get the job done, however, and while he has a save and four holds on the season, he's also been charged with a blown save and a loss in his last two appearances. Should Hendriks miss significant time, Bummer could find himself in the mix for saves, but Kendall Graveman would likely be the next man up for Chicago.
