Colorado at Arizona

First-place Colorado is crushing the baseball, second in the league in runs, batting average and on-base percentage, tops in slugging. Starter Jon Garland is throwing well, only seven walks in 25 innings and 26 hits allowed. Arizona is in the middle of the pack offensively and goes with lefty Patrick Corbin. He's been on a roll, but not against Colorado: the Rockies have given Corbin fits, as he's 0-1 with a 6.75 ERA in three starts against them. Rockies CF Dexter Fowler is four for five with a double and a triple against Corbin, and 1B Jordan Pacheco is five for eight with a double against him, so grab the very live dog with a reliable, veteran starter. Play the Rockies.
