I like this match up as the White Sox have played much better in day games than during the night. Peavy gets to go back to the National League where he's most comfortable in terms of players he faces. White Sox are 24-8 in their last 32 inter league games and 42-18 in their last 60 as a favorite. While the Nationals who are stuggling right now with just 3.10 runs per 9 vs. RHP in their last 10 games are just 3-13 in their last 16 as a dog +110 to +150.
