We roll with the Under here between these two teams that are headed to a very likely post-season. You have a Colorado team that just took 4 games from LA and their pitching staff give 11 runs that entire series and though it is the Dodgers and they are struggling, the fact that this pitching staff has held on strong this entire year when many thought they would not is testament to their will.
You have a pitcher in Walker who is hitting his stride when it counts the most for Arizona giving up 2 runs in about 23 innings and has dropped his era all the way down to 3.33. He has been particularly sharp against Colorado giving up 5 runs in 23 innings of work and we like the fact he is pitching at home where he has consistently pitched well and note the Under is 11-4 for the Rockies against a right handed pitcher and the Under is 4-1 for the Diamondbacks when they face a team with a winning record.

I like the UNDER tonight between these 2 teams on Tuesday night.
