Rockies-Diamondbacks Preview

The Associated Press

After falling short in repeated attempts to make franchise history, Arizona Diamondbacks left-hander Patrick Corbin will next try to help his club match its longest win streak of the season.

The first-time All-Star will seek to bounce back from his lone loss in 2013 by leading the surging Diamondbacks to a fifth straight victory in Sunday's finale with the visiting Colorado Rockies.

Corbin (9-1, 2.49 ERA) had six chances to become the first Arizona pitcher to start 10-0, but that pursuit ended with a 9-1 loss at the New York Mets on Tuesday. He was also attempting to become the first lefty starter to begin 10-0 since Ron Guidry won his first 13 decisions for the New York Yankees in 1978.

Corbin has been backed by a combined 10 runs of support in his past six starts after receiving 48 in his first 11 outings, but he didn't help himself against the Mets by giving up a season-high five runs over six-plus frames. He was charged with four of those runs while failing to record an out in the seventh inning.

"I felt fine. I just left a couple of pitches up," Corbin said.

Corbin might have better success in this start as he's 2-0 with a 1.59 ERA in his last three matchups against Colorado, including two this season. He also would appear to have a good chance to get some better run support considering the way the Diamondbacks have been hitting coupled with the way scheduled starter Roy Oswalt (0-3, 7.88) is pitching.

Arizona (46-41) is batting .306 and has outscored opponents 26-8 in its past four games.

Paul Goldschmidt, also named to his first All-Star team, hit one of Arizona's three home runs in an 11-1 rout of Colorado on Saturday. Cody Ross matched a franchise record with five of his team's 12 hits, as the Diamondbacks opened up a 4 1/2-game lead atop the NL West for the first time this season.

Arizona will next attempt to match its five-game win streak from May 6-10 and sweep the Rockies (42-46) for the first time since Aug. 29-30, 2011.

Oswalt has lost in all three starts since returning to the majors June 20. The three-time All-Star gave up five runs and nine hits over five innings in Tuesday's 8-0 loss to the Los Angeles Dodgers.

"I think I'm trying to be too fine. Trying to throw that nine-inning shutout with 70 pitches instead of being aggressive like I've always been," he said.

Oswalt is 9-3 with a 2.35 ERA in 13 career starts against Arizona with the most recent matchup April 26, 2011.

The right-hander has never faced Goldschmidt, who is 5 for 13 in his last three games and batting .379 with five homers and 10 RBIs in his last eight in Phoenix.

Carlos Gonzalez, one of two Rockies players voted as an All-Star starter, is 1 for 7 with five strikeouts against Corbin. He went 4 for 4 and hit his NL-best 24th homer in his return from a sore back Saturday.
