"I'm frustrated," said Humber in an SI.com article. "I'm doing my best, it's just the last two or three times out there, it's been rough. I'm definitely hoping for better results. I'm doing the best I can to make that happen, but right now it's kind of a grind."
Humber, who threw a perfect game on April 21, has allowed 20 runs in 13.1 innings. He has failed to record a win since then, going 0-2 over that span. Zach McAllister, who was brought up from the minors prior to the game, pitched a solid six innings and notched his first career win.
The Indians were led by Michael Brantley and Casey Kotchman, who both drove in three runs. The White Sox had a strong game from Alexei Ramirez, who drove in three RBI.
Nick Hagadone recorded his first career save for the Indians.
The White Sox will face the Tribe later this evening in the second game of the twin bill.
