White Sox placed RHP Jake Peavy on the 15-day disabled list with a non-displaced fracture in his rib cage. Peavy will be shut down for the next 4-6 weeks and could struggle to return to Chicago's starting rotation before the All-Star break. The 32-year-old right-hander has posted a 4.30 ERA, 1.16 WHIP and 66/15 K/BB ratio in 67 innings this season. He will be missed.
