All season long, the Dodgers' record has been among the tops in the Majors, as they've been consistently in the running for the distinction of best team in baseball.

But based on recent results, the Dodgers are still fighting for the distinction of best team in their own region.

The Freeway Series resumes Friday night in Anaheim, with the Dodgers and Angels squaring off for the second time this season. The Angels hold a 52-37 edge over the Dodgers since Interleague Play began in 1997, and have won five straight series since 2009.

Dan Haren gets the ball for the Angels, coming off a stretch of three games during which he has allowed 11 earned runs in 16 2/3 innings. Haren was a little better his last time out, but was done in by a four-run sixth against Arizona.

Like most ballplayers, Haren is a very routine-oriented person, preferring to pitch on his usual four days' rest whenever possible. But with an off-day and the return of righty ace Jered Weaver to the rotation, Haren will be throwing on six days' rest for the first time this season.

Haren hasn't pitched on six days' rest since last Aug. 26, when he lasted only 4 1/3 innings and allowed seven runs.

Opposing Haren is 27-year-old Chad Billingsley, who has struggled against the Angels. The righty is 1-4 with a 4.10 ERA against the crosstown rival in eight games (six starts). His last outing was promising as Billingsley gave up only three runs in an eight-inning complete game in 2011, but he hasn't defeated the Angels since 2008.

After winning two straight starts, Billingsley allowed five runs -- four earned -- in six innings in a loss to the White Sox on Saturday.

Prior to that loss, the righty went seven innings against both Philadelphia and Seattle, only giving up one run in each game. Billingsley has had an up-and-down season after winning his first two starts of 2012.

"The biggest thing when you talk about Chad is the consistency," Dodgers manager Don Mattingly said.

Dodgers: Belisario making impact in 'pen

After missing the first 25 games of the season while serving a suspension for a positive cocaine test, Dodgers reliever Ronald Belisario has become one of the bullpen's most reliable arms.

Belisario has gone 3-0 this season with a 1.25 ERA in 21 games.

"He's been really good and been a good citizen, no issues of any kind," Mattingly said. "He's been great. We've had injuries to Javy Guerra and Matt Guerrier for extended times, and Belly has given us a late-inning guy."

Angels: Trout staying hot

Since the start of May, no one has been hotter than Angels center fielder Mike Trout. His .355 average during that time leads the American League, as do his 40 runs scored and his 85 times reaching base.

Trout's performance in the Angels' three-game series against San Francisco had Giants manager Bruce Bochy very impressed.

"I'll tell you what, that Trout -- they've got a special player over there," Bochy said. "What's amazing is his balance and discipline."

• The Angels placed right-hander Jerome Williams on the disabled list Wednesday, clearing room for ace Jered Weaver to return and start that night's game. Williams, who was born with asthma, passed out when he walked into the clubhouse after his last start Monday.

Worth noting

• In 16 outings against the Dodgers, Haren is 5-5 with a 3.27 ERA. Dodgers right fielder Andre Ethier has had plenty of success against Haren in his 46 plate appearances against him. Ethier is hitting .386 with two homers, five doubles and seven RBIs.

• The Angels have won six consecutive Interleague series at home.
