While they've labored for much of the past month, the Arizona Diamondbacks have a winning record against San Diego during that span and have recorded their only two win streaks at the Padres' expense.
After ending their longest skid in four years, the Diamondbacks will try to produce another set of back-to-back victories versus their NL West rivals Sunday.
Arizona (60-88) had dropped 19 of 25 and seven in a row before a 10-4 victory Saturday. Mark Trumbo had three hits and drove in three runs as the Diamondbacks improved to 5-4 against San Diego (68-79) since Aug. 21 and 11-7 overall.
They scored a combined six runs in the first two innings Saturday after totaling 13 during their lengthy skid.
"We came out pretty aggressive. We put a lot of guys in motion," manager Kirk Gibson said. "It worked out for us very well."
Arizona will next try to secure its third win streak since Aug. 9, and Trevor Cahill (3-11, 5.23 ERA) will seek to end a personal three-game skid. The right-hander has a 9.69 ERA in his past three starts, including a 3-1 loss in San Diego on Sept. 1, but showed some improvement over his previous two outings in a 7-2 defeat to the Los Angeles Dodgers last Sunday.
Cahill pitched five scoreless innings before getting charged with three runs while failing to get out of the sixth. He yielded just two hits in his 5 2-3 innings, but issued four walks and has given out a combined 17 in 19 1-3 innings in his last four games.
"(I need to) just be more aggressive, throw strikes," Cahill told MLB's official website. "That's kind of been what I've been working on for a long time. ... If I get ahead, don't try to put him away with the nastiest pitch, just make a good pitch and not necessarily go for the strikeout."
Cahill lasted only four-plus innings in his lone start against San Diego this season while yielding three runs, five hits and a season-high six walks in his 93 pitches.
Odrisamer Despaigne (3-6, 3.55) failed to make it out of the fifth inning in his most recent outing Monday at the Dodgers and was charged with a career-high seven runs in a 9-4 defeat, his third in a row.
The rookie right-hander has a 5.27 ERA in his last five starts after registering a 2.72 ERA in his first nine major league games.
He's gone 1-1 with a 2.41 ERA in three matchups with Arizona and yielded one run over seven innings against the Diamondbacks on Sept. 2 but did not get a decision in a 2-1 win. He allowed four runs in five innings in his only start in Arizona, a 5-1 loss Aug. 22.
Despaigne is 0-5 with a 6.67 ERA in six road starts since a 6-0 win in San Francisco in his MLB debut June 23.
