The Chicago White Sox have scratched tonight's schedule starter, righthander Jake Peavy, because of back spasms Peavy is suffering. Instead, Chicago will start lefthander Hector Santiago.
Santiago, 25, has a 2.51 ERA in 14 innings over 7 appearances this year, all in relief. Four of Santiago's 42 appearances with Chicago last season were starts.
The lefthander going for Chicago likely means that Jeff Baker will get another start today, either in place of 1B Mitch Moreland, LF David Murphy, or DH Lance Berkman.
