Howard set for precautionary MRI on left knee

PHILADELPHIA -- Ryan Howard will have a precautionary MRI on Monday to take a look at his sore left knee.

The power-hitting first baseman was held out of the Phillies' lineup Sunday against the Reds, and he said his knee was bothering him more than usual. Howard did not travel with the team to Miami on Sunday evening, but he was scheduled to join the Phillies on Monday after getting the MRI.

"Yesterday was when it really kind of kicked in more than normal," Howard said about his knee. "It's been acting up a little bit since Spring Training, but I've been able to tough it out. Yesterday, it kicked up a little bit, so we'll see."

Howard said he told manager Charlie Manuel that his knee was giving him some trouble before the game, and Manuel kept the lefty out of the lineup. Howard added he was available to play if needed, and was in the on-deck circle at one point, but did not enter the game. Manuel said he would be surprised if Howard played Monday when the Phillies open a three-game set in Miami.

The 2006 National League Most Valuable Player is hitting .245 with six home runs and 22 RBIs in 41 games.

Ruiz to undergo MRI on strained hamstring

PHILADELPHIA -- Carlos Ruiz did not travel with the Phillies to Miami on Sunday evening and will get an MRI on his strained right hamstring.

The catcher injured his leg while running the bases in the second inning of a 3-2 win over the Reds on Sunday. Ruiz said he was unsure if the strain will land him on the disabled list, but he did not sound optimistic about avoiding it.

"It surprised me, it happened [so quickly]," Ruiz said of the injury. "It was that last thing I thought was going to happen, because before I felt great."

After his MRI, Ruiz said he will join the Phillies in Miami on Tuesday. However, the team sent catcher Humberto Quintero to Florida so he could join the Phillies' roster if Ruiz ends up on the DL.

Ruiz, who missed time at the beginning of the season to serve a 25-game suspension, is batting .235 with two RBIs in 16 games. He hit .325 with 16 homers and was named a National League All-Star last season.

Quintero is currently with Triple-A Lehigh Valley, but he spent time earlier in the season with the Phillies while Ruiz was serving his suspension. The 33-year-old started seven games behind the plate and hit .250.

Erik Kratz replaced Ruiz on Sunday, and hit the first of back-to-back home runs off Aroldis Chapman that won the game for the Phillies in the ninth inning. Kratz will become the Phillies' everyday catcher if Ruiz is placed on the DL.

Cloyd to be called up to start Tuesday

PHILADELPHIA -- The Phillies announced Sunday that they will call up right-hander Tyler Cloyd from Triple-A Lehigh Valley to start Tuesday against the Marlins.

Thanks to two off-days in a span of four days, the club had the luxury of needing just four starters on its roster this week.

With Roy Halladay on the disabled list because of shoulder surgery, Cloyd made a spot start for the Phillies on May 10 against the D-backs. The 26-year-old took a no-decision after allowing two runs in 6 1/3 innings. Cloyd also pitched for the Phillies last season, and in seven Major League starts, he is 2-2 with a 4.58 ERA.

The Phillies also said a corresponding roster move will be made by Tuesday to make room for Cloyd on the Major League roster. General manager Ruben Amaro Jr. said before Sunday's game there is a "likelihood" setup man Mike Adams, who has been badgered by a mild back strain, will land on the disabled list, although nothing has been finalized.

After throwing Sunday and feeling "really good," Adams said that he still was not sure about the possibility of landing on the DL, but added he was traveling with the team to Miami.

He also noted that his shoulder bothered him when he played catch, but said that was due to not throwing in a while.

Adams hurt his back last Sunday in Arizona, has not pitched since May 10 and had an injection in his back earlier this week. If Adams is put on the DL, the move would be retroactive to May 11.

Phillies relievers trying to right the ship

PHILADELPHIA -- The Phillies' bullpen is not just allowing small deficits to get out of hand, but the team's relievers are allowing inherited runners to score at a staggering rate.

In 43 games, Phillies relievers have allowed 46.3 percent (25-of-54) of inherited runners to cross the plate. The only group of Major League relief pitchers since 1974 to have a worse mark throughout an entire season was the Reds' bullpen in 1977, which permitted 48.1 percent (74-of-154) of inherited runners to score.

"I have a big concern about our bullpen," Phillies manager Charlie Manuel said Saturday. "If we can't hold people, how can we win the game? You can say you've got to score runs to win, but at the same time, how many runs do you have to score?"

Manuel said this after the bullpen watched a four-run deficit turn into a 10-run loss against Cincinnati. The combination of relievers B.J. Rosenberg, Jeremy Horst, Phillippe Aumont and Chad Durbin allowed six runs in the final two innings.

Durbin has allowed 12 earned runs in 13 1/3 innings this season, and the right-hander said that he and others in the Phillies' bullpen are in the process of trying to figure it out.

"I think the last five to six outings have been in games that are six- and seven-run games where you're figuring out what to do," Durbin said. "I thought the last couple times out, my stuff's been a lot better. So you kind of turn the corner. It's hard to really evaluate yourself in games that are eight, nine runs."

Revere returns to lineup for finale vs. Reds

PHILADELPHIA -- Ben Revere made his return to the Phillies' lineup Sunday after beginning the previous four games on the bench.

It marked the first start in a week for the speedy center fielder, who was batting second in the order and laced a one-out double in his first at-bat. Revere had made some late-inning appearances on the bases and in the field lately, but he was held out of manager Charlie Manuel's lineup in the past week as the Phillies faced two left-handed starters, and John Mayberry Jr. was producing at the plate.

Mayberry went 6-for-12 in the first three games that he started in center field last week, but struck out in each of his four at-bats Saturday in the Phillies' 10-0 loss to the Reds.

Manuel said Revere -- who entered Sunday hitting .237 this season with a .286 on-base percentage -- has spent a little extra time in the batting cage with assistant hitting coach Wally Joyner. Manuel added that he has not given up on Revere, whom the Phillies acquired from Minnesota in the offseason.

"I look on almost every team I've ever managed, there's definitely at-bats for four outfielders, maybe even five, at times," Manuel said. "You can get plenty of at-bats -- you might not get 600 -- but you can get enough to be satisfied."

Prior to his week-long hiatus from the starting lineup, Revere had 10 hits in his last 28 at-bats, and his on-base percentage currently sits at .438 in May.

Young makes first start at first for Phils

PHILADELPHIA -- Michael Young has his first baseman's mitt in his locker every time he goes to the ballpark, but until Sunday, it had not served him a purpose this season.

Even though Young said he had not practiced at first base in Spring Training, he got his first start as a first baseman for the team in its series finale against the Reds.

"I've used my hand, and banged my fist in [my first baseman's mitt], but that's the most action it's seen," said Young, who has not played first base since last October, when he was with the Rangers.

The 36-year-old has played every infield position besides pitcher and catcher in his career, but he has only played third base in his time with the Phillies.

Young noted that he told manager Charlie Manuel that he could play first base if needed before the season started. And when he learned he would be there Sunday morning, he took it in stride.

"I'm not concerned about it at all," Young said. "The first two months of the season, third base wasn't an issue, I feel the same about first base."

Young has been the most consistent hitter for the Phillies this season, and his .300 average and .395 on-base percentage entering Sunday were the best on the team. He will be in the No. 3 hole in the order Sunday, as the Phillies' regular first baseman, Ryan Howard, received the afternoon off.

Now in his 14th Major League season, Young has played a lot of baseball and said the most important thing about the quick transition to first base will be to anticipate plays. When asked if he would have any jitters moving to the right side of the infield after a long time away, Young had a simple response.

"I don't get nervous playing baseball," he said.
