Harang identifies mechanical flaw

ANAHEIM -- Aaron Harang believes he and pitching coach Rick Honeycutt figured out what led to his career-high eight walks Tuesday night in Oakland.

Harang said game video revealed a mechanical flaw in the way he separates his hands at the beginning of his windup.

"It's all about timing, and we worked on it in the bullpen yesterday," said Harang on Friday before the Dodgers opened a three-game set at Angel Stadium. "If I don't split my hands properly, my arm is late and my pitches are high, above the strike zone."

Harang starts again in Sunday's Freeway Series finale.

Guerra's progress headlines LA's DL report

ANAHEIM -- Injured Dodgers pitchers Javy Guerra and Ted Lilly resumed working out with the club on Friday, joining position players Matt Kemp and Mark Ellis as they continued to recover on the disabled list.

Guerra had the most good news, throwing off the bullpen mound for the first time since June 5 right knee surgery, and throwing hard.

"It went great," said Guerra, who said he's definitely ahead of schedule and was able to continue throwing uninterrupted despite the arthroscopic operation to clean out loose bodies.

Lilly, however, threw for the first time since completely shutting down because of left shoulder irritation that has had him on the DL since May 24. Lilly softly lobbed about 15 throws and appears a long way from returning to game action.

Kemp and Ellis continued sprinting and baserunning drills as they recover from hamstring and lower leg injuries, respectively.

Manager Don Mattingly said there is no timetable for their return, although Kemp is planning to attend the All-Star Game and compete in the Home Run Derby (he's National League Derby captain), even if he isn't active to play in the game. Ellis is now doing all baseball activities after an emergency fasciotomy and could begin a Minor League rehab assignment around the same time as Kemp.

"When guys are progressing, running the bases, starting and stopping, they're getting close to going somewhere to play," said Mattingly.

Mattingly expects fewer mistakes

ANAHEIM -- Dodgers manager Don Mattingly had Dee Gordon out early with instructor Maury Wills on Friday working on bunting, one of several fundamental breakdowns the Dodgers experienced while being swept over three games in Oakland this week.

But Mattingly emphasized that neither Wills' tutoring of the leadoff hitter, nor the extra batting practice taken by a handful of players afterward meant there was panic in the air after losing three straight (on eight total hits) and four of five.

"Extra hitting on the road is nothing new for us, it's just routine," he said. "We're not going to change who we are. We are understanding that we'll go through stretches when we lose games here and there. I tell the guys we'll be patient with that as long as we're fighting and not lose our identity and play smart.

"Some of the frustrations in Oakland were that they had too many easy innings, and we made too many mistakes on defense. We weren't executing. As a club, we can't afford to overcome a lot of mistakes. We've got to play mistake-free. We didn't do that, and we didn't deserve to win those games."

Hawksworth returns to mound

ANAHEIM -- Dodgers pitcher Blake Hawksworth, on the disabled list all season following two elbow operations, made his first game appearance on Friday night in a Minor League injury rehab assignment.

Hawksworth allowed one run on one bunt single in one inning with two strikeouts for the Class A Rancho Cucamonga Quakes.

Hawksworth, who spent all last year with the Dodgers, underwent what should have been relatively minor arthroscopic surgery on his right elbow Jan. 11 to remove a bone spur and scar tissue. But a post-surgical infection developed that required a second cleansing procedure and powerful antibiotics, setting back his recovery.

The 28-year-old had a decent first season with the Dodgers after being acquired from the St. Louis Cardinals for Ryan Theriot. He went 3-5 with a 4.08 ERA in 49 appearances, with one stint on the DL with a strained groin muscle.

Hawksworth served as a middle and long reliever for the Dodgers. Because he is out of options, the club could lose him if it attempts to outright Hawksworth to the Minor Leagues.
