Ethier, Hanley held out of starting lineup

LOS ANGELES -- Center fielder Andre Ethier sat out of Friday night's game against the Cardinals -- a precautionary move, manager Don Mattingly said.

"He's been having some bumps and bruises and kind of little stuff here, little stuff there, and for me, it's been growing a little bit, and I'm just trying to cut that off at the pass," Mattingly said.

"I know he's not going to be 100 percent after one day but just keep him from going over the top."

Ethier's right knee has bothered him since the team's road trip to Kansas City. It was swollen Friday, a day after he fouled an Adam Wainwright pitch off of the leg. Scott Van Slyke started in center in place of Ethier.

Meanwhile, shortstop Hanley Ramirez was out of the lineup for the fourth straight game with an arthritic right shoulder. He's day to day after an MRI on Thursday revealed no structural damage.

Ramirez took ground balls on the Dodger Stadium field Friday, but he didn't make any throws to first base.

"Hanley's up stretching with the boys here," Mattingly said. "And he's going to try hit inside, maybe try to throw inside, and pretty much everything he does other than stretch is going to be inside. I'm hoping to have him available in some respect."

Mattingly said he didn't anticipate Ramirez would need to go on the disabled list.

Rojas, Gordon bonding in super fashion

LOS ANGELES -- Second baseman Dee Gordon has a well-known affinity for Superman. He wears a shirt with the iconic logo under his Dodgers jersey, and he's even worn a red cape in the Dodger Stadium clubhouse.

After Thursday night's game, infielder Miguel Rojas -- whose locker is to the left of Gordon's -- was wearing a Superman shirt of his own. Did he borrow it?

"No, I have it from Triple-A," Rojas said. "I was doing good with it while I was there, so I keep it on."

Rojas and Gordon are not only partners in crime-fighting attire, but in the last few games, they've been double-play partners as well, with Rojas filling in for ailing Hanley Ramirez at shortstop.

Both infielders have showcased their range on a defense that has looked sharper overall. Rojas, who was called up from Triple-A Albuquerque on June 6, said he's enjoyed the opportunity to play with Gordon up the middle. In the process, the two have strengthened their relationship.

"It's been better," Rojas said. "I played against him when I was growing up in the Reds organization, and I was also a shortstop. And playing with him now, I'm having a lot of fun because he gives me that freedom of being a young guy, too.

"I'm doing pretty good with him. I'm really happy to play with him."

Worth noting

• Left fielder Carl Crawford, on the disabled list since May 27 with a left ankle sprain, ran outside Friday for the first time since he suffered a setback in mid-June at the team's training facility in Arizona.
