LOS ANGELES -- Matt Kemp and Andre Ethier's numbers are nearly identical over the last week. However, they haven't been the numbers the Dodgers have come to expect from the sluggers as the pair are in the midst of their own troubling slumps.

Both Kemp and Ethier entered Wednesday's game having gone 1-for-22, dating back to Aug. 15 for Kemp and Aug. 16 for Ethier.

"Those are the guys you count on," manager Don Mattingly said. "We talk about it early in the year before this year started. Matt is going to have to have a big year. Andre is going to have to have a big year. We are going to need production from those guys to be a part of it."

Kemp went 1-for-3 with solid at-bats Tuesday night that encouraged Mattingly, and he's been steady the entire season when healthy for the most part.

As for Ethier, it's been a struggle at times since hitting .366 in May. He batted .218 in June and now he's batting .197 in August after hitting safely in 15 out of 18 games in July.

Mattingly said he is concerned, but he also pointed out how Ethier picked things up on the team's most recent 10-game road trip. Although the right fielder had a hit in seven of those games, as well as a few timely hits, he still finished the trip 8-for-40 and he's gone 0-for-8 against the Giants since returning home.

"He's streaky like everybody else," Mattingly said. "... Andre is no different than Matt. We need him to go. That's where it is."

The manager pointed out how hard he notices Ethier is working to right the ship and added he's been doing everything the team has asked. However, he said both he and Ethier expect more.

Hawksworth has surgery; Hairston next

LOS ANGELES -- Following the Dodgers' 8-4 loss against the Giants on Wednesday, it was revealed that Jerry Hairston will have season-ending arthroscopic hip surgery in the next couple of weeks and that Blake Hawksworth had season-ending arthroscopic shoulder surgery earlier in the day.

Hairston, who hit the disabled list Aug. 12 with left hip inflammation, is expected to need four to six months to recover. The veteran utility man was hitting .273 through 78 games this season, his first with the Dodgers.

Hawksworth has been on the DL all season after right elbow surgery, and he had his rehab shut down at the beginning of July after feeling pain in the area of his clavicle. The reliever is expected to miss another year.

Hairston is under contract next year at $3.75 million, while Hawksworth is a non-tendered player.

Dodgers put in extra work on fielding

LOS ANGELES -- The Dodgers' clubhouse, typically filled with players at their lockers, was uncharacteristically empty when it opened up to the media at 3:40 p.m. prior to Wednesday's game. That's because the team was already on the field for a meeting and pitchers' fielding practice drills before batting practice.

"It was for our guys who haven't been here to show them some of the stuff that we do," manager Don Mattingly said. "The whole thing is based on three guys out there."

He said every team does its infield drills differently, and with a number of new players, that was the reason why the team was out there early.

Worth noting

• James Loney will host the Natural Balance Pet Foods Dodgers Dream Foundation Bowling Extravaganza on Thursday evening while the Dodgers are off. Kemp, Mattingly, Trey Hillman, Kenley Jansen, Luis Cruz, Hanley Ramirez, Shawn Tolleson, Ronald Belisario and A.J. Ellis are all scheduled to join Loney at Lucky Strike Lanes L.A. Live for the event.

• The Dodgers shuffled their rotation for the weekend vs. the Marlins, flipping Clayton Kershaw and Aaron Harang to pitch on Saturday and Sunday, respectively, following Chad Billingsley, who will pitch Friday night's series opener as originally scheduled.
