PHOENIX (AP) - The refrain is getting painfully familiar for the sputtering Arizona Diamondbacks: a bad outing for a starting pitcher.

Trevor Cahill couldn’t make it through the fifth inning for the third time in his four starts and the Los Angeles Dodgers beat the Diamondbacks 8-6 on Sunday to complete a three-game sweep.

His performance followed equally poor showings by starters Brandon McCarthy and Wade Miley in the first two games.

Cahill (0-4) was overpowering at times but walked three and gave up a three-run home run to Adrian Gonzalez in a four-run third inning.

Arizona is 4-11 and the main reason is obvious.

“The pitching, the starting pitching. Is there a question about that?” Gibson said. “We got five innings out of the guy today, four, that’s tough. The one thing you want to go well is you want to get innings out of your starting pitchers.”

Gonzalez homered for the fourth consecutive game and finished with 10 RBIs in the series. He has 27 career home runs and 87 RBIs against the Diamondbacks, most among active players.

“Man, he’s smoking the ball,” teammate Matt Kemp said. “He’s probably the best hitter in the league right now.”

Kemp and Juan Uribe also homered for the Dodgers, who scored 22 runs in the series.

“This is a good place to hit,” Gonzalez said. “You go out here and take BP (batting practice) and the ball carries out of the ballpark. You take some of those swings and it kind of makes you feel better as a hitter.”

Dan Haren (2-0) allowed three runs in 5 2-3 innings to get the victory.

Mark Trumbo hit a three-run home run and Eric Chavez had a solo shot for the Diamondbacks, who are off to a 4-11 start.

Dee Gordon stole a career-best four bases, the most by a Dodger in a game since Rafael Furcal did it against Arizona in 2007.

Cahill went four innings plus two batters, allowing seven runs - six earned - on seven hits. Cahill struck out eight but walked five.

Asked why Cahill can be good for a stretch then fall apart, Gibson said, “I think you’d have to ask Trevor that. I don’t have an answer for you.”
