Despite recent surge, Brown to stay in Minors

MINNEAPOLIS -- The Phillies are falling fast in the National League East standings.

Maybe a fresh face would help.

Fans have been clamoring for Triple-A Lehigh Valley outfielder Domonic Brown to make another appearance in a Phillies uniform, but don't bet on that happening anytime soon. Sure, Brown is hitting .316 with two doubles, three home runs, five RBIs and a .986 OPS this month, but he is hitting .269 with 10 doubles, two triples, four homers, 22 RBIs and a .738 OPS overall this season.

"The plan from the start was getting him to play and play regularly," Phillies assistant general manager Scott Proefrock said before Wednesday's game against the Twins at Target Field.

  • 142 wins
  • 110 wins

"Quite frankly, he wasn't healthy, basically the first two months of the season. He had a bruised knee and a hamstring injury. The last couple of weeks it seems like he's started to play regularly and be healthy. Playing over a two-week period doesn't exactly establish ... it's not the amount of time we want him to play. He still needs to play.

"He still needs to work on his defense. He went two months without hitting a home run. Now he's hit four. His whole game just needs a chance. He needs to play and continue to progress. Just because he's had a good two weeks ... we want him to have some sustained success, and that hasn't been achieved yet."

Brown batted .245 with five homers and 19 RBIs in 56 games with the Phillies in 2011.

Galvis to be in back brace for three weeks

MINNEAPOLIS -- Doctors in New York concurred with the Phillies' diagnosis that Freddy Galvis has a pars fracture in his lower back.

Galvis will be in a brace for the next three weeks.

"Then we're going to reexamine him and see where we're at," Phillies head athletic trainer Scott Sheridan said before Wednesday's game against the Twins at Target Field. "Based on his symptoms and that kind of stuff, we might be able to begin some stuff with him exercise-wise, but we really won't know a lot more until we get to that time period. The biggest thing right now is just trying to get him comfortable, make him feel better and try to get this thing to heal."

Sheridan said it was too early to say how much time Galvis will miss, but it should be a significant amount of time.

"It's hard to just go, 'Oh, the season is over,'" Sheridan said. "I think a lot just depends on how he responds after the first three weeks."

Galvis, whose L45 vertebrae is fractured, has had some back issues in the past, most recently in winter ball. But he just recently developed the full fracture.

"It's not an uncommon injury in baseball," Sheridan said. "You want to treat it appropriately. If you let these go they can progress into other problems."

Asked if this could bother Galvis in the future, Sheridan said, "I don't think so. I think it probably changes the way he approaches things going forward."

Polanco returns to lineup Wednesday

MINNEAPOLIS -- The Phillies got a little healthier Wednesday when Placido Polanco returned to the lineup.

Polanco had not played since June 5 because of torn cartilage in his left wrist.

His return should boost the Philadelphia offense, but it's not the offense that needs a lot of help. The Phillies are averaging 4.79 runs per game since April 22, which ranks sixth in baseball. Their .330 on-base percentage and .427 slugging percentage each rank seventh in that span.

Polanco's biggest boost should come defensively. Phillies third basemen have committed four errors in the last six games without Polanco.

Worth noting

• Second baseman Chase Utley (left knee injury) served as the designated hitter for Class A Clearwater on Wednesday, going 2-for-5 with a double, an RBI and two runs scored.

• Ryan Howard (left Achilles surgery) participated in an extended spring camp game Wednesday in Clearwater, Fla.

• Outfielder Laynce Nix (strained left calf) also hit in the extended game. "I don't think he's got near as much ground to cover as hard," Proefrock said. "Without any setbacks I think we could see him heading out on a rehab within a week or so."

• Right-hander Justin De Fratus (sprained right elbow) is throwing from 120 feet. "There's a light at the end of the tunnel for him," Proefrock said.

• Right-handers Mike Stutes (right shoulder inflammation) and David Herndon (right elbow inflammation) are scheduled to meet with team physician Michael Ciccotti next week. They have progressed slowly from their injuries.
