BALTIMORE -- Josh Reddick was held out of Saturday's lineup as a result of his crash into the right-field wall on the final out of Friday's game.

The A's right fielder said there were no issues with his head or neck, only a little bit of stiffness, and he expects to be available to pinch-hit if needed.

"I thought I was capable of playing," Reddick said. "But they just said, 'No,' as a precaution, just to give it a day and give it a little bit of rest. But [I'll] still be available off the bench."

With two outs in the ninth inning on Friday, a line drive off the bat of Nick Markakis sent Reddick sprinting toward the wall.

After leaping to secure the catch, Reddick slammed into the lightly-padded concrete wall, sending a "shock" up his back and knocking the wind out of him.

"It was pretty scary," Reddick said. "Looking back, it didn't look as bad as it felt. Just never been scared like that before."

After spending a few minutes face-up on the warning track with his eyes closed -- he said he was playing it safe, given that the game was over and there was no rush to get back up -- Reddick regained normal breathing and was carted to the clubhouse.

Reddick iced the bruised area behind his right shoulder, and said Saturday there was no bruising.

"It scared us all for a bit, but he came out of it better than I thought today," A's manager Bob Melvin said. "But we're going to be careful with him, at least at the start today. He might be able to pinch-hit."

Reddick participated in batting practice and fielding drills as normal on Saturday, even making time to try on his new full-body Spiderman costume in the clubhouse.

While Melvin and trainer Nick Paparesta said Reddick would be evaluated again before a decision is made about Sunday's lineup, all three seemed optimistic that he'd be ready to go.

"If everything goes well today, we'd look to get him back out there again tomorrow," Paparesta said.

"Back out there tomorrow, starting in the outfield," Reddick said. "I'll do it again if I have to catch the ball."

McCarthy moves forward; Braden suffers setback

BALTIMORE -- While Brandon McCarthy will be taking a step forward with his rehab on Monday, Dallas Braden is dealing with a minor setback, A's trainer Nick Paparesta said on Saturday.

After throwing a bullpen without issue on Saturday, McCarthy boarded a flight to Reno, where he will make a rehab start for Triple-A Sacramento on Monday.

McCarthy, who has been on the disabled list since June 20 with recurring right shoulder soreness, is expected to throw about 65 pitches.

Braden, scheduled to face live hitters on Friday during a live batting practice in Arizona for the first time since undergoing shoulder surgery last May, only got four or five pitches into his warmup routine before straining his left groin muscle.

Paparesta said Braden's shoulder felt "great," but the team opted to "completely shut him down" until the groin irritation subsides.

Braden received treatment and therapy on Saturday and will be reevaluated on Monday, when the A's return to Oakland.

"Obviously, Dallas is kind of down in the dumps about it, because he was getting close and going to see some hitters," Paparesta said. "[He] feels like he's got the injury bug a little bit right now, but we'll get him back out there as soon as he's ready to get going. Keep the shoulder strong."

Weeks hits second in Reddick's absence

BALTIMORE -- Jemile Weeks retook his usual spot near the top of the order on Saturday, but A's manager Bob Melvin made it sound like he shouldn't get too used to it.

Melvin said Weeks' move back to the top had more to do with Josh Reddick getting the day off than any permanent change in lineup construction.

Weeks had made 87 starts hitting first or second before sliding down to ninth this week, where Melvin said he likes to have him.

"I think he's doing well down there," Melvin said. "So it might just be today's lineup. It might not."

Melvin said there was a good chance Jonny Gomes will claim the No. 2 spot in the order against left-handed starter Wei-Yin Chen on Sunday.

Gomes started in the two-hole in each of the A's five matchups with lefties this week before getting the day off against right-hander Tommy Hunter on Saturday.

"That's worked pretty well for us," Melvin said. "We're not afraid to mix it up. You try to have some stability within the lineup. I think we've had some stability recently with lineups against lefties."

Gomes is hitting .440 since the All-Star break, a shift he credited to playing multiple days in a row rather than anything having to do with his spot in the order.

Neither Gomes nor Weeks said their spot in the order affects their approach, but the two options clearly have different impacts on the offense.

While Gomes owns the better on-base percentage, Weeks is a threat with his speed, as evidenced by his 13 steals.

Crisp day to day with left hamstring tightness

BALTIMORE -- Coco Crisp left Saturday's game prior to the bottom of the eighth inning due to tightness in his left hamstring, A's manager Bob Melvin said.

"We'll see how he is tomorrow," Melvin said. "[He is] day to day."

Crisp was 0-for-4 with a strikeout before he was removed.

Jonny Gomes replaced Crisp in the lineup and played left, while Yoenis Cespedes took Crisp's place in center.

In the eighth inning of Friday's game, Crisp was seen flexing his left hamstring after charging in to make a catch on a shallow fly off the bat of O's second baseman Omar Quintanilla.

Crisp remained in the game Friday, finishing 2-for-5.

Worth noting

• Cliff Pennington started swinging on Friday, a first since going on the disabled list with left elbow tendinitis on July 20. Trainer Nick Paparesta said Pennington will take Sunday off and then resume on Monday, "hopefully" participating in batting practice at some point during the A's 10-game homestead.

• Brett Anderson, recovering from the Tommy John surgery he underwent last July, is scheduled to make his second rehab start with Triple-A Sacramento on Tuesday, Paparesta said. He will be limited to five innings or 75 pitches, whichever comes first.
