Colorado at San Francisco

Colorado is off a division showdown with the red-hot Dodgers and got swept. Now they step down to play the awful Giants. Colorado is fifth in baseball in runs scored and tenth in slugging. The Rockies are 18-7 during Game 1 of a series, plus 20-6 versus a team with a winning percentage below .400. Rockies righty German Marquez (5-3, 3.92 ERA) has allowed only one earned run in each of his last three starts. He faces a terrible San Francisco offense that is #27 in runs scored, #28 in on-base percentage, and last in slugging. The Giants are off an 8-2 home loss to the New York Mets on Sunday, part of a 5-21 run. Giants righty Jeff Samardzija (2-9, 4.74 ERA) is 0-3 with a 9.33 ERA versus Colorado this season. San Francisco is 17-35 against a right-handed starter, and the Rockies are 10-1 in the last 11 meetings. Play Colorado.
