The White Sox scratched pitcher Jake Peavy from his scheduled Thursday night start at Texas due to back spasms, the team announced via Twitter.
Hector Santiago will get the start in place of Peavy. The left-hander's 2013 numbers include a 2.51 ERA and 1.12 WHIP with 11 K and 3 BB in 14 innings.
Peavy, who has has been impressive early in the 2013 season -- 3-1, 3.38 ERA, 1.13 WHIP and 39/6 K/BB ratio over 32 innings -- is considered day-to-day.
Peavy has struggled against the Rangers, especially at Rangers Ballpark in Arlington. In four career starts, three of which have been in Arlington, he’s 0-2 with a 7.59 ERA and has allowed four homers in 21 1/3 innings.
