His mound opponent, A's right-hander Brandon McCarthy, is hoping a chronic balky shoulder doesn't mess up what has been a promising season.
Harang is making his first career start against the A's and coming off of a career-high 118-pitch effort. He gave up no earned runs as the Dodgers beat the Angels, 5-2, and looks to continue his hot June that has seen him become one of the club's most consistent starters.
Harang has bounced back from a rough start to the season, going 1-2 with a 5.72 ERA through April.
In May, he went 2-1 with a 2.67 ERA in five starts, and in June, he is 2-0 with a 1.89 ERA against the Rockies, Phillies and Angels. All three outings were quality starts and he heads into Tuesday's game 5-3 with a 3.59 ERA in 13 starts.
Dodgers manager Don Mattingly did not want Harang's effort against the Angels to go overlooked. Mattingly credited Harang's performance as the reason why the team was able to eventually come back late in the game.
"You don't want to be behind late because you're not going to win too many of those," the manager said. "It's nice to get one, but you only get that if you hang close."
McCarthy (5-3, 2.79 ERA) is scheduled to make his 12th start, but has dealt with shoulder soreness three separate times this season.
He was on the DL from May 18 to June 2 with a strained right shoulder, and though he reported no problems in his initial two starts after being reinstated, the injury flared up again after that second outing June 7 against the Rangers.
After a strong effort against the Rangers in which he pitched seven innings, allowed three hits and one earned run in a 7-1 A's victory, McCarthy has missed his last two turns in the rotation.
McCarthy's right shoulder has troubled him for several years. The 28-year-old has missed time on five occasions in the past five years and was out for six weeks last season with the same issue.
Dodgers: Versatile Herrera rolls along
Super utility man Elian Herrera continues to play well wherever he's placed in the lineup.
Herrera started in left field for the second time in Sunday's 2-1, 10-inning victory over the White Sox and was 3-for-4 to raise his batting average to .305.
The 27-year-old has started 26 games including 10 at third base, nine at second base and five in center field.
A's: Moss providing a spark
Rookie Brandon Moss has been a pleasant surprise at first base in the 11 games since he was promoted from Triple-A Sacramento of the Pacific Coast League. He was 0-for-2 with a pair of walks in Sunday's 2-0 loss to the Padres, but he's hit hit six home runs while playing first base, even though his natural position is as an outfielder.
"Here's a guy that's had some opportunities or a couple opportunities before," A's manager Bob Melvin said. "When he got the opportunity here, even though it wasn't a position he's familiar playing with, you could kind of tell that he was pretty serious about taking advantage of this opportunity. To this point, I can't imagine him doing any better than he has."
Dodgers outfielder Bobby Abreu did not start Sunday's game after going 2-for-4 Saturday night, but he singled in a pinch-hit appearance to lead off the ninth and ultimately scored the tying run. He later walked in the the game-winning 10th-inning rally.
In 38 games since signing with Los Angeles, Abreu is hitting .320 (32-for-100).
