Keller (0-1) allowed four earned runs on six hits and three walks across 3.1 innings while striking out three to take the loss against the White Sox on Thursday.
Keller's struggles continued from Opening Day and he's allowed 10 runs in 4.2 innings over two starts. In addition, his command isn't there right now, as he's walked five batters during that stretch. The 25-year-old got shelled Thursday, surrendering home runs to Yermin Mercedes and Yoan Moncada in the first inning. Keller will try to get back on track in his next start against the Angels on Wednesday.
