The White Sox traded Graveman to the Astros on Friday in exchange for Korey Lee, Jeff Passan of ESPN.com reports.
He becomes the fifth different pitcher dealt by the White Sox ahead of the Aug. 1 trade deadline. Graveman finished the 2021 season in Houston, so manager Dusty Baker and the coaching staff are already familiar with what the 32-year-old reliever can contribute. He figures to operate in a setup role ahead of Astros closer Ryan Pressly. Graveman had a 3.48 ERA, 1.21 WHIP and 42:20 K:BB through 44 innings this season with Chicago.
