I like the Over. Neither pitcher, esp Contreras, has faced any real monster lineups over the last 3-5 games. It's been hot here all day (as you know) and the wind is blowing slightly straight out. I think the hot field surface may provide some lift to hit balls in this hitter friendly field. I don't think either pitcher goes past the 6th, maybe less, and we'll see a lot of the pens IMO. I don't think the large Contreras, with his liking to throwing a lot of pitches, will help him in this heat or against this lineup. I also think the White Sox lineup is going to score a lot off this Boston staff and it's outfield arms.
GL on your action.
edit....
Reg play
