NEW YORK -- When the Yankees take their hacks against Mike Pelfrey on Saturday, they will face a different Pelfrey than the one they saw a year ago.

"I would almost say I've changed from being a sinkerball guy to a four-seam guy," Pelfrey said. "There are times when I'll only use the sinker when I get in trouble. I've changed."

Unlike in previous seasons, when Pelfrey has attacked hitters with more than 70 percent sinkers, he is now throwing the pitch less than half the time. Pelfrey credits that to his newest pitch, the split-fingered fastball. But the right-hander is also throwing nearly three times as many changeups and curves as he did last season.

Concerned Mets place Maine on DL

NEW YORK -- After a brief and messy exchange of words, the Mets placed starting pitcher John Maine on the 15-day disabled list on Friday with what the club termed "right shoulder weakness."

The move came less than a day after manager Jerry Manuel removed Maine from his start against the Nationals in Washington due to concern over the right-hander's lack of velocity.

"I just need some answers," Manuel said on Friday, before Maine underwent an examination at Citi Field.

The Mets recalled right-hander Elmer Dessens from Triple-A Buffalo and expected him to arrive at Citi Field during Friday's night's Subway Series opener against the Yankees.

Still smoldering after being removed from Thursday night's 10-7 win after just five pitches, Maine said at roughly 4 p.m. ET on Friday that he had not yet been informed of the plan, and that he had not spoken with Manuel since their confrontation on the mound in Washington.

Manuel intimated that the results of Maine's examination would determine whether he takes his next turn in the rotation. After the examination revealed shoulder weakness, Maine landed on the disabled list, casting both his future and that of the rotation in doubt.

After Thursday's game, Manuel said that he removed Maine due to the righty's lack of velocity. Maine said he was simply warming on the mound and that he felt fine, though the radar gun provided evidence to the contrary -- after throwing his first two pitches 82 and 83 mph, Maine threw each of his final three pitches at 85 mph.

For most of this season, Maine had been sitting in the high 80s with his fastball, touching 90 mph on occasion.

After the game, Maine stressed that he was unhappy with the way the situation was handled. In addition, pitching coach Dan Warthen called Maine a "habitual liar" regarding his own health. But Manuel said on Friday that Maine knew he was going to be under close surveillance and that the situation should not have come as a surprise.

"I think there's something there physically," Manuel said. "But I could be wrong."

Maine has a history of physical ailments, and he has never been the same since undergoing surgery to shave a bone spur from his shoulder after the 2008 season. But the right-hander has insisted all year that he is now healthy -- even if the Mets disagree.

"He wants to compete, and I'm trying to protect him from what I thought could be a dangerous situation for him and for the team," Manuel said before the examination. "That was basically what the confrontation was about -- him competing and me trying to protect him."

"I'm not on bad terms with anybody," Maine said. "I don't want to be on bad terms with anybody. I understand their position and what they've got to do, and I hope they understand my position. I want to pitch. If I have to go out there and throw left-handed, that's what I want to do, because I want to go out and pitch."

To replace Maine, the Mets have few options. Already forced to plug Hisanori Takahashi and R.A. Dickey into a crumbling rotation, the club could call on Minor Leaguer Pat Misch to step into Maine's spot. But Misch is not an ideal solution.

Dessens had been pitching exclusively out of the bullpen for Buffalo, going 5-0 with a 2.12 ERA.

Playing it safe, Mets give Castillo rest

NEW YORK -- Only minutes after releasing their starting lineup for Friday's game against the Yankees, the Mets issued a new version -- this one without second baseman Luis Castillo.

Castillo, who has been battling a bone bruise in his left foot since Spring Training, was unavailable for comment on Friday. He has been wearing an orthopedic pad in his left shoe but has been playing under some duress.

"We're going to try to give him tonight off and see how he responds to the treatment and what have you," manager Jerry Manuel said. "It's in a very tricky area. Any time you walk or any time you do anything, it can cause some problems."

Manuel said that if possible, he will rest Castillo again on Saturday. Alex Cora replaced Castillo in Friday's lineup, batting second.

For Castillo, disappointment during the Subway Series is nothing new. Last year at Yankee Stadium, the second baseman dropped a popup in the bottom of the ninth inning on June 12, allowing the tying and winning runs to score and sending the Mets to a walk-off defeat.

Former Mets favorites reunite in Queens

NEW YORK -- Mike Hampton spent only one year playing for the Mets, but the experience left a mark on the starting pitcher, whose career spanned 15 seasons.

"It was the highlight of my career, winning the NLCS and then getting the chance to pitch in the World Series," Hampton said on Friday.

That year, of course, was 2000, when the Mets made it to the Fall Classic before losing to the Yankees in five games.

Before the 2010 version of the Mets took on the Yankees on Friday night, the club welcomed back six players from that World Series team -- Hampton, John Franco, Benny Agbayani, Edgardo Alfonzo, Rick Reed and Turk Wendell.

The players hung out on the field during batting practice and presented the second "Teammates in the Community Award" during a pregame ceremony.

And for a few, it was a chance to get a first look at 2-year-old Citi Field.

"It's nice," Agbayani said. "I might reconsider [retirement] and try to get a one-month contract."
