ANAHEIM -- Chris Davis (right trapezius muscle strain) was out of Friday's starting lineup for the second consecutive game, although the 26-year-old said he was feeling better and expected to return Saturday.

"My range of motion is back," said Davis, who was in good spirits on Friday afternoon. "It's still painful, but as long as I can turn my head, it's the biggest thing. That's obviously the way I look to hit. So I'm going to take [batting practice] today and I should be able to play tomorrow."

Davis said he woke up Thursday with a sore neck, stemming from a diving catch on Wednesday, and he couldn't throw without discomfort so he alerted the team's medical staff. The trapezius is a large muscle that supports the shoulders and arms and the rotation of the scapula necessary to raise the arms above shoulder level. Davis said it's not an injury he's had before and it isn't related to the right shoulder strain that put him on the disabled list for three weeks last season.

Asked if the team had dodged a bullet with Davis, manager Buck Showalter said he wasn't ready to go there just yet, reminding reporters of outfielder Nolan Reimold, who is out for the season after undergoing neck surgery.

"A lot of those things you feel like going into it it's going to be day-to-day thing," Showalter said. "When you are dealing with necks and backs and stuff like that, I'll believe it when I see it."

The 26-year-old Davis is hitting .274 with 14 homers and 40 RBIs in 70 games this season, and is 4-for-12 with a double, a homer, two runs scored and five RBIs in three games this road trip.

Roberts may need surgery on injured hip

ANAHEIM -- An MRI exam of Orioles second baseman Brian Roberts' right hip on Thursday showed a labrum tear, and manager Buck Showalter said Friday that the veteran will seek a second opinion on the injury in Atlanta.

One of the options would be surgery for Roberts, who was placed on the disabled list on Tuesday with a sore groin and alerted the Orioles to some hip issues after that.

"I traded texts with him back and forth. [He's] obviously a little depressed about the physical issue," Showalter said. "We were hoping to get better news.

"I feel sorry for Brian, he worked so hard to get back to this point, to have something else crop up, it's frustrating for him."

Roberts, who has played in just 115 games since the beginning of the 2010 season, missed more than a year while recovering from a concussion and made his long-awaited season debut on June 12. But he struggled following that three-hit game, and had a .182 average with two runs scored and five RBIs in 17 games before landing back on the DL.

Tolleson to replace disappointed Arrieta

ANAHEIM -- The Orioles' roster was one short on Friday night, as the team optioned Thursday's starter, Jake Arrieta, to Triple-A Norfolk and is expected to activate infielder/outfielder Steve Tolleson prior to Saturday's game.

Tolleson, who was optioned to Norfolk on June 27, is not eligible to called up until Saturday, since it's not an injury situation with Arrieta and Tolleson needs to have the minimum 10-day stay in the Minors. As for the decision to option Arrieta, who went 3 2/3 innings for the second consecutive start, manager Buck Showalter said he had a tough and emotional conversation with the 26-year-old after Thursday's game.

"He was going to stay out here, and I have a conversation that really disrupts his whole life," Showalter said. "And it's frustrating for me, I don't want to do it. But I also have to do what's best for Jake and the Orioles.

"I think he's scheduled to be the last starter after the break [for Norfolk] just to give him the benefit of a couple work days. [Director of pitching development] Rick Peterson is going there after the break, [Arrieta] will work with [pitching coach Mike Griffin]. We talked a lot about what's going on and what some of his challenges have been and more important how to help. It's a tough place to experiment here. You are competitive, you are trying to win here every night.

"I just don't want him to look at it like the whole world is caving in on him."

Arrieta was the third starter from the Orioles' Opening Day rotation to be sent to the Minor Leagues -- joining Tommy Hunter and Brian Matusz, who tossed a complete-game shutout in his first Triple-A start Friday -- leaving Baltimore's second-half rotation unclear. Jason Hammel and Wei-Yin Chen will pitch the first two games, with Chris Tillman going the third game after the All-Star break.
