Sandberg considering shuffle in Phils' outfield

TORONTO -- The Phillies have some outfield problems with no immediate solutions.

Ben Revere misplayed a catchable ball in center field to start the bottom of the seventh inning Wednesday at Rogers Centre, which sparked a nine-run rally in a 10-0 loss to the Blue Jays. Tuesday night, Jays third baseman Juan Francisco hit a fly ball to center with a runner on third in the 10th inning at Citizens Bank Park, but Revere, who does not have a good arm, couldn't throw out the winning run at the plate.

Phillies manager Ryne Sandberg started Tony Gwynn Jr. in center field Thursday, saying he liked Gwynn's bat in the lineup against Toronto knuckleballer R.A. Dickey.

But Revere's production offensively and defensively has been a concern, which creates the possibility that Marlon Byrd could see time in center field in the future. Revere's .600 OPS before Thursday's game ranked 163rd out of 186 qualifying players in baseball. The Phils' center fielders had a combined .646 OPS, which ranked 22nd out of the 30 teams.

The production has been worse in left field. Domonic Brown's .564 OPS ranked 174th, and Phillies left fielders had a combined .561 OPS, which ranked last.

"He's an option for center field, yeah," Sandberg said about Byrd. "He has experience there. From what I've seen, his first-step quickness and his reads are outstanding. And he has an above-average arm."

Byrd played two games in center field last season with the Mets and 46 games in center with the Cubs and Red Sox in 2012. He played all 118 games there with the Cubs in 2011.

"I've talked to him about it," Sandberg said. "And he likes playing center field. In my experience, a lot of guys that have played the corners and center field like center field the best, as far as seeing the ball and getting even better jumps. You can see the angles in front of you. The job that he does in right field with that -- with jumps, positioning and going back, going to the gap and coming in -- he's been outstanding."

Of course, playing Byrd in center only seems to make sense if Darin Ruf rejoins the team at some point and is producing at one of the corner spots. Otherwise, the Phils are moving a productive right fielder to center field, shifting concerns elsewhere.

Ruf, who has been on the disabled list since Spring Training with a strained left oblique, began a rehab assignment Thursday with Class A Clearwater, where he went 0-for-3 with a walk and played nine innings at first base.

"He's just a candidate," Sandberg said again about Byrd in center field. "I'm not going much further than that, long-term or anything like that. He's a candidate in center field."

Phils option Galvis to get him more at-bats

TORONTO -- The Phillies optioned infielder Freddy Galvis to Triple-A Lehigh Valley following Thursday's 12-6 loss to the Blue Jays.

They selected the contract of Triple-A infielder Reid Brignac on Friday to take his place on the roster. He is hitting .284 with five home runs and 21 RBIs in 30 games. Brignac hit two homers Thursday.

Galvis' demotion did not come as a surprise. He went 0-for-3 with one walk and one strikeout Thursday. Galvis is hitting .048 (2-for-42) with one RBI, three walks and 12 strikeouts in 16 games.

"He needs to go play, get at-bats and gather himself a little bit," Phils manager Ryne Sandberg said. "He might have been rushed up here a little bit, with not having Spring Training."

Galvis missed some time in March when he suffered a MRSA infection in his left knee.

"I missed a lot of games," Galvis said. "I missed a lot of at-bats. That's why I'm going down, you know? To get my at-bats, try to get my approach and try to swing the bat better. I don't feel sad. I don't feel bad or nothing. I'm just going to go there and work on my hitting. That's it."

Rollins' return to field still up in the air

TORONTO -- Jimmy Rollins started his second consecutive game as the Phillies' designated hitter on Thursday.

Rollins has not started at shortstop since Sunday, when he tweaked his right groin. Could he play at shortstop this weekend against the Mets at Citi Field?

"We'll see," Ryne Sandberg said. "It's day to day with how he's doing. He felt good about [a pregame workout Wednesday]. Good progress with that. I think that keeps it a day-to-day thing, though, so that's positive."
