When the pitching matchup is somewhat even, which I think Madison Bumgarner vs. Antonio Senzatela is close, then the Rockies are always great value as home underdogs in that altitude. Senzatela has historically been much better in the thin air of Denver and Colorado is above .500 vs. lefties and Bumgarner has an ERA near 5.00 in his career at Coors Field. Back the Rockies here at home to get the underdog win for us.
