While Ian Kennedy couldn't buy a home win early this season, it's been more than three months since he's lost at Petco Park.
After dropping his first five decisions at home, Kennedy has gone 4-0 with a 3.33 ERA over his last eight starts there. The right-hander has struck out 50 over 46 innings during that stretch while holding opponents to a .227 average.
Kennedy (10-11, 3.65 ERA) delivered again Saturday in a 2-1, 10-inning win over the Los Angeles Dodgers, yielding one run and four hits over seven innings. He hasn't lost at home since a 5-3 defeat to Minnesota on May 20.
This marks Kennedy's fifth start in the series since the Diamondbacks traded him to San Diego in July 2013. He won 7-4 at Arizona on Aug. 24, improving to 2-1 with a 5.73 ERA against his former team.
"It was a little different my first time, but this time was no different," Kennedy said. "I've been a Padre for over a year now and it kind of goes away."
The Padres (66-72) lost for the second time in eight games with Wednesday's 6-1 setback, going 0 for 3 with runners in scoring position. It was also only their fourth defeat in the last 20 home games.
David Peralta went 2 for 5 with two RBIs and Josh Collmenter threw seven sharp innings as Arizona snapped a season-worst eight-game road losing streak. Peralta has hit safely in seven straight against the Padres, going 11 for 27 with two triples.
The Diamondbacks (58-81) also got a boost from Daniel Hudson, who threw a scoreless inning of relief in his first big league appearance since June 2012. Hudson is the fourth pitcher to undergo Tommy John surgery in consecutive years and return to the majors.
"It was great. It was a lot of fun. I don't really have much to say. It's just a lot of emotions right now. I'm just glad I was able to get in there. It went as well as it could have," said Hudson, who won 16 games with Arizona in 2011. "Even if I go out tomorrow and it blows again, it was all worth it."
Randall Delgado (2-3, 5.85) is set to make his first start since April as Arizona goes to a six-man rotation. The right-hander has been working an a breaking ball to make his mid-90s fastball and changeup more effective.
"It's a pitch he didn't have last year and really early this year," general manager Kevin Towers told MLB's official website. "It was one of the reasons we dropped him out of the rotation; he was a two-pitch pitcher. He's going to get a couple of starts in September. Hopefully he does a good job."
Delgado gave up nine runs over 7 1-3 innings in two April starts. While he three-hit San Diego in a 10-0 win July 26, 2013, for his only complete game, Delgado has since gone 0-1 with an 8.31 ERA in three appearances - one start - in the series.
