One hot pitcher and one who hopes he's heating up go head-to-head Wednesday night when the Colorado Rockies and San Francisco Giants continue their three-game series. The Giants outlasted the Rockies in a pitchers' duel in the opener Tuesday night, with a bases-loaded walk plating the winning run in the eighth, one inning after starters Derek Holland and Chad Bettis had exited a 1-1 game. San Francisco, seeking a fourth straight win, will send Madison Bumgarner (1-2, 3.20 ERA) to the mound Wednesday.
