Young 'progressing,' doing well in right field

PHILADELPHIA -- Outfielder Delmon Young, rehabbing from microfracture surgery on his right ankle, continues to play extended spring training games in Clearwater, Fla.

"He's progressing," Phillies general manager Ruben Amaro Jr. insisted. He said Young was scheduled to play seven innings in the outfield Thursday, Friday and Saturday.

"Then we'll decide when he's going to go out on a real rehab assignment," Amaro said. "He's not ready to be here yet. When he's ready to be here, he'll be here."

Asked how Young has looked in right field, a position he has not played in seven years, Amaro said, "He's moving around pretty good. So far he's done well. He hasn't misplayed any balls or anything like that. I don't know if he's going to be a Gold Glover out there, but he needs to be at least adequate. So far he hasn't done anything to dissuade us."

Lannan placed on DL with strained tendon in knee

PHILADELPHIA -- Phillies left-hander John Lannan thought he simply tweaked his left knee in the first inning Wednesday against the Reds in Cincinnati.

He did much worse than that.

The Phillies placed Lannan on the 15-day disabled list Thursday because of a strained quadriceps tendon in his left knee. Phillies general manager Ruben Amaro Jr. and manager Charlie Manuel said Lannan could miss six to eight weeks.

"It's a fairly serious injury," Amaro said. "I know John was upset about it, but there's not much you can do other than rehab it and come back as soon as possible."

The Phillies will call up left-hander Joe Savery before Friday's game to temporarily take Lannan's spot on the 25-man roster. But a replacement for Lannan's spot in the rotation will need to be announced before Monday's game against the Pirates, which would have been Lannan's turn to pitch.

The Phillies have options in Triple-A Lehigh Valley, but their best option there might be left-hander Adam Morgan and he pitched Thursday in Pawtucket. Amaro said right-handers Tyler Cloyd, Jonathan Pettibone and Ethan Martin also will be considered. Amaro said Double-A Reading prospect Jesse Biddle is not an option. He also said the Phillies could look outside the organization to find a replacement, although he said the choice likely will come from Triple-A.

"We have a few options there," Amaro said. "We're kicking them around right now."

Because Morgan (1-0, 1.42 ERA in three starts) threw 100 pitches in five innings Thursday, Amaro said it is unlikely he gets the nod to pitch Monday. But that does not mean Morgan could not help at some point. Amaro said they will choose a pitcher for Monday then continue to evaluate the spot.

"That could be kind of a day-to-day thing," he said. "See how that person performs and if that person performs well, then we'll stay with them. A lot of it depends on how that guy throws and we'll kind of take it one day at a time on that."

Cloyd (0-2, 7.07 ERA in three starts), Pettibone (0-1, 9.64 ERA in two starts) and Martin (1-0, 4.82 ERA in two starts) have not pitched as well as Morgan, but they are on the 40-man roster.

"It's frustrating because I actually feel really, really good," Lannan said, referring to the way he was pitching before the injury. "It's just this little thing. It just sucks it had to happen. Right now I'm just playing it by ear, just getting healthy no matter how long it takes."

Revere dropped from Phillies' leadoff spot

PHILADELPHIA -- Phillies manager Charlie Manuel gave center fielder Ben Revere a shot in the leadoff spot, but with the Phillies struggling terribly offensively he made a change before Thursday's game against the Cardinals at Citizens Bank Park.

He returned Jimmy Rollins to the top spot and hit Revere, who is batting .194 with a .194 slugging percentage, seventh.

"I talked to Charlie when I came to the field, and he's like, 'It's something that we're going to try, a little switchup and we'll see how it works,'" Revere said. "He told me, 'I'm not giving up on you, I know you're a good hitter and everything,' it's just that I hit down there before, it's no biggie. I'm struggling a little bit but trying to figure out that swing and figure out these pitchers and I'll be rolling real soon."

Brown 'a lot better' but sits in favor of Galvis

PHILADELPHIA -- Domonic Brown said he is ready to play.

He left Wednesday's game in Cincinnati because of soreness in his lower back. But Brown said he felt better after taking medication Wednesday and felt fine taking swings in the batting cage before Thursday's game against the Cardinals at Citizens Bank Park.

"I feel a lot better," Brown said.

But Phillies manager Charlie Manuel had Freddy Galvis playing left field Thursday. It was the first time Galvis had played outfield in his big league career, although he played there occasionally during Spring Training.

Brown had an X-ray, which came back negative. The Phillies determined Brown did not need an MRI after his discomfort cleared up overnight.

Asked if Brown was available to pinch-hit Thursday, Manuel said, "Trainer said he's kind of OK, but at the same time, I don't want to put him out there and then have to take him out again. It's too early. Last night he came to me and told me that he couldn't go. [I thought] maybe I should be a little bit cautious on him."

Walks drought a symptom of Phillies' woes

PHILADELPHIA -- The Phillies did not walk once in three games in Cincinnati. It's the first time since 1995 they went three consecutive games without a walk and just the second time it has happened in 50 years.

Said general manager Ruben Amaro Jr.: "I think it's ridiculous that we've had no walks in three days. I cannot believe it. More importantly, it's about not just walks, but producing, and we haven't done that. We haven't gotten hits, period. We haven't gotten hits with runners in scoring position, we haven't gotten hits to lead off innings. We need more people on base and more offensive production. You've got to give some credit to the pitchers, but not all of it. We just need to be better. It's as simple as that. Right now we're not."
