On Tuesday, Jeff Samardzija (1-3, 6.23 ERA) hopes to build upon his previous outing against the Rockies, when he worked a season-high 6 2/3 innings in a no-decision at San Francisco on May 17. Lifetime, he's 4-5 with 3.84 ERA in 16 games (12 starts) against Colorado, including 2-2, 4.87 in eight games (five starts) at Coors Field. Rockies left-hander Kyle Freeland (4-5, 3.28) will oppose Samardzija.
