Left-hander Patrick Corbin shoots for his 13th win of the season on Sunday when the Arizona Diamondbacks play the rubber match of their three-game series with the San Diego Padres at Chase Field.
Corbin won his third straight start on Tuesday against the Chicago Cubs, as he held them to a run and four hits over six innings to run his record to 12-1, while lowering his ERA to 2.31.
"Patrick wasn't very sharp early, but he's just really good at battling through things," Arizona manager Kirk Gibson said. "It's only fitting he got the win."
Over his last three starts Corbin has pitched to a 1.31 ERA and has held the opposition to a .184 batting average. He's also tallied 26 strikeouts in 20 2/3 innings during that span and has allowed two runs or less in 16 of his 20 starts this season.
Corbin has beaten the Padres twice this season and is 2-2 with a 4.05 ERA in five games (4 starts) against them.
Arizona has won 18 of Corbin's 20 starts, and he's 8-0 with a 1.54 ERA in his 11 outings at Chase Field.
San Diego, meanwhile, will counter with righty Tyson Ross, who is 1-4 with a 3.35 ERA. Ross earned his first win of the season on Tuesday in Milwaukee, as he held the Brewers to a run and a pair of hits in six innings in his first start since mid-April.
This will be his first-ever start versus the Padres.
After losing Friday's opener, San Diego bounced back on Saturday, as Yonder Alonso had three hits while driving in four runs to help the Padres cruise to a 12-3 win.
Chris Denorfia had a two-run blast and scored three times while Carlos Quentin drove in two runs. Chase Headley and Andrew Cashner each connected on solo shots for the Padres, who have won four of their last six games.
Cashner (7-5) allowed three runs on four hits and five walks while fanning five in six innings. All three runs came off home runs, which snapped Cashner's steak at 49 2/3 innings without allowing a home run. It was the longest current streak in the majors among starters.
Tyler Skaggs (2-3) was tagged for seven runs on just three hits and five walks over 3 2/3 innings, his shortest outing of the year.
"For whatever reason he had no command of his fastball," Gibson said about Skaggs. "It seems like his velocity goes down as the game goes on."
Paul Goldschmidt slammed a two-run homer, his 23rd of the year, and Miguel Montero had a solo home run for the D'backs, who had a two-game winning streak stopped.
Goldschmidt, who had been mired in an 0-for-11 rut before the home run, could rest on Sunday.
"I think Goldy is dragging a bit right now," Gibson said. "He's been carrying a lot of people around for a long time."
The Padres are 7-4 in this series this season.
