Colorado at Arizona

Colorado is fifth in baseball in runs scored with a winning road record. This is a big series for both teams and the Rockies have been up to the challenge, taking the first two games 5-4 and 4-2 as a dog each time. Colorado has won six in a row, as well as eight in a row on the road. Rockies 22-year-old righty German Marquez (10-6) has been very good and the team is 7-0 away against a team with a winning record. Arizona is on a 1-4 skid at home. Diamondbacks lefty Patrick Corbin (4.16 ERA) has allowed batters to hit .285 off him for the season. He comes off a terrible game, giving up 11 hits, and eight runs in 4+ innings of a 10-6 loss to San Diego. Corbin owns a 5.02 ERA against the Rockies in 16 career appearances (15 starts) and is 0-2 this season against them. Arizona is also 6-13 when Corbin faces the National League West. Take Colorado.
