German Marquez is 7-3 and is 3-2 with a 3.02 ERA on the road and he threw a one hit shutout last time he faced the Giants. Jeff Samardzija is 4-6 with a 4.23 ERA and he went seven scoreless against the Rockies last time he faced them. However, he has a 6.15 ERA over his last five starts and a 5.24 ERA in June. The Rockies are 12-5 when Marquez starts and the Giants are 7-8 when Samardzija starts. I'll back the better offense here with the Rockies on Wednesday afternoon.
