Kyle Freeland doesn't come to mind when rating the best pitchers in the National League. Freeland, though, has been excellent this month emerging as Colorado's top starter. He has a 0.93 September ERA in 18 1/3 innings giving up just two runs in three starts. 

The Giants have a below average offense. The Under has cashed in 10 of its last 12 games on grass. 

Carlos Rodon was San Francisco's original starter. But he was scratched. So this is going to be a bullpen game beginning with John Brebbia, who is 1-0 with a 1.35 ERA in 17 career appearances against Colorado. He hasn't allowed an earned run to the Rockies in 5 1/3 innings this season. 

I don't mind a bullpen game from the Giants because each of their pitchers should be fresh and able to go all out for strikeouts, which is important for an Under at Coors Field.
