C.J. Wilson's struggles are a bit more concerning to the club with the majors' second-best record.
Hyun-Jin Ryu yielded two hits over seven dominant innings, Hanley Ramirez had a two-run single and the Dodgers wrapped up the Freeway Series with their third straight win, 7-0 over the Angels on Thursday night.
The Angels (67-47) managed just two runs on eight hits in the final 24 innings of the series, falling three games behind Oakland atop the AL West standings.
Their biggest concern is Wilson (8-8), who had another rough outing in his second start back from the disabled list. After failing to get out of the second inning last week, he yielded six hits and four walks to the Dodgers in his fifth straight winless start.
"We're a really good team, and we need to put it together," Wilson said. "For me, it's better than my last outing, but that's not saying much, because I think I could have thrown right-handed and pitched better last time."
Adrian Gonzalez added a late two-run single as the NL-leading Dodgers (66-50) thoroughly shut down their Southern California neighbors in Anaheim, allowing one run in two games to win the Freeway Series for the first time since 2006.
David Freese's one-out double in the fifth was the first hit for the Angels, who were shut out for the third time all season. They have lost three straight for the first time in more than two months.
"There are going to be stretches where you're not pitching well and not playing well," catcher Chris Iannetta said. "We're not playing bad right now. We're just not playing to our potential. ... Hopefully we can tread water, hang in the race and not fall too far behind from Oakland."
Although Angel Stadium was packed with its biggest crowd in 16 years, the blue-clad fans had all the fun in the Freeway Series finale.
Ryu (13-5) was brilliant in his fourth victory in five starts, striking out four and allowing just two runners to reach third base. The Korean left-hander threw a shutout last year in his only previous start against the Angels.
"It just felt really good to do it again," Ryu said through a translator. "Last year, I had that really symbolic game for me. I just tried to duplicate the outcome. It's a great thing to be on a winning streak and to take the series here."
The Dodgers moved to a season-best 16 games over .500 and improved the majors' best road record to 36-23.
Mike Trout went 0 for 3 with a walk on his 23rd birthday. The ballpark was festooned with dozens of congratulatory signs from Angels fans.
The Angels briefly showed life when Albert Pujols' sixth-inning double ended an 0-for-20 combined skid by Trout, Pujols and Josh Hamilton. But Yasiel Puig sprinted and leaped to catch Hamilton's inning-ending drive at the warning track.
Dodgers: Josh Beckett is having an MRI exam after feeling pain in his hip while playing catch Wednesday. He will miss his scheduled start Friday.
Angels: Wilson is healthy enough to pitch, but his return from a sprained ankle hasn't gone smoothly. With Tyler Skaggs sidelined for the near future with a strained forearm, the Angels don't have many options to give Wilson more time.
Dodgers: Roberto Hernandez (6-8, 3.87 ERA) will start in Milwaukee one day after the Dodgers acquired him in a trade with Philadelphia.
Angels: Jered Weaver (12-6, 3.59 ERA), who hasn't lost since June 21, will open a series against the Boston Red Sox.
