The White Sox designated righty Jeff Gray for assignment to open a spot on the 25-man roster for Jake Peavy, tweets MLB.com's Scott Merkin. The move leaves the Sox with 35 players on their 40-man roster.
Gray, 29, tossed 13 1/3 innings for the Sox this year, including a nice three-inning effort yesterday. The team had signed Gray to a minor league deal in December after he'd been outrighted by the Cubs. Gray had been part of the December '09 deal that sent Jake Fox and Aaron Miles to Oakland.
