Phils send Rosenberg to Triple-A to regroup

LOS ANGELES -- The Phillies opened the season with four right-handers in the bullpen, other than closer Jonathan Papelbon.

Three of them have been sent to Triple-A Lehigh Valley because of ineffectiveness: Brad Lincoln, Justin De Fratus and B.J. Rosenberg. The Phillies optioned Rosenberg on Wednesday to make room for left-hander Cole Hamels, who made his 2014 debut against the Dodgers at Dodger Stadium.

Rosenberg's departure left Mike Adams, Shawn Camp, Jeff Manship and Papelbon as the bullpen's right-handers.

"On the flip side, some other guys have stepped up and have done a nice job," Phillies manager Ryne Sandberg said. "[Left-hander Mario] Hollands, Manship, that's how it goes. Those guys are pitching and we're keeping an eye on everybody, and it's a long season. But we have some other guys that are doing well."

Earlier this week, Phillies general manager Ruben Amaro Jr. said Rosenberg had value because he has good stuff. But the stuff had not played in his first eight appearances. He had a 7.11 ERA and had allowed eight hits, including one double, one triple and three home runs.

"Allow him to get the feet on the ground and get some confidence," Sandberg said, when asked about the decision to option Rosenberg. "He's going to work on some things."

The Phillies want him to work on a cut fastball to complement his four-seam fastball.

"In the past, he's a guy who needed some games under his belt to get some arm strength," Sandberg said. "In September, he was throwing 95 to 97 mph. Now he's at 93. That's been his track record. He's been working on a cutter, but he hasn't been able to feature it in a game. He hasn't had the confidence. Hopefully he'll add some quality there and get some success and some confidence."

Camp and Manship both signed Minor League contracts in the offseason. But Sandberg said Manship, who opened the season with the team, could be used in the middle to late innings, depending on the situation. He views Camp more as a long man.

Adams' presence is felt early on

LOS ANGELES -- Right-hander Mike Adams threw a perfect eighth inning Tuesday against the Dodgers at Dodger Stadium.

It was his second appearance of the season, but it came in a big spot with the game tied.

"He came in last night throwing strikes," Phillies manager Ryne Sandberg said. "That's huge. We're talking about strikes out of the bullpen, challenging the hitter, down in the zone, mix pitches, but come out of the bullpen throwing strikes has been the message from Day 1. I would say the guys that are here now have been doing that. That's good. That's good that some guys did step up."

Asche loses more time to Galvis

LOS ANGELES -- Cody Asche started eight of the season's first 10 games, but just five of the past 11.

That included Wednesday's game against the Dodgers at Dodger Stadium, his third consecutive game on the bench. Phillies manager Ryne Sandberg chose Freddy Galvis to start at third base.

"I'd say some of the biggest improvements we've made the last three games is solid pitching and solid defense," Sandberg said. "Freddy has been a part of that, so he finds himself in the lineup. Freddy has been part of making plays and solid defense. Pitching and defense gives you a chance to win."

Galvis has just one hit in 18 at-bats for a .056 batting average in seven games, while Asche is hitting .196 (9-for-46) with two doubles, one home run and three RBIs in 17 games. Asche was the team's Opening Day third baseman and viewed as a potential everyday player, but it is trending away from that.

Asked if he might need to talk to Asche about his current situation, Sandberg said, "I don't need to because I already have. I just told him to be ready to go in any capacity. The biggest change in the last three games is quality pitching and good defense behind. Freddy has been a part of that combination for the last three games."

And Galvis' offense?

"He's hit some balls good," Sandberg said. "His role on the team as an offensive player is doing the little things and staying on top of the ball. He's an average or average-plus runner. He needs to just use the whole field and not get too big with his swings. He's hit some good balls and hasn't had anything to show for it. He has the ability to put the bat on the ball and be a situational guy. I see that coming with some added at bats."
