May 24.10: Mejia to stay in pen.

Until they change their minds again, the Mets have made a decision – hopefully definitive for at least the remainder of the season – on Jenrry Mejia.

The prospect with the million-dollar arm will remain in the bullpen.

Manager Jerry Manuel confirmed last night what many surmised after Manny Acosta was optioned to Triple-A Buffalo instead of Mejia to make room for Ryota Igarashi’s return from the disabled list.

“You have a young man who has a tremendous arm, tremendous upside,’’ Manuel said. “If you take what he gives you in small bits, it’s very serviceable, even at the big league level.’’

Several things went into the decision, notably when Mejia started altering his delivery Thursday in Washington. Altered deliveries lead to arm problems and the Mets want to nip possibility early.

During the series with the Nationals, Manuel had suggested Mejia was likely to be the one to go to the minor leagues to make room for Igarashi.

Starting might still be in Mejia’s future, but not for now, and you would be correct if you thought this move had something to do with Manuel’s immediate job future.

“If we wanted to have him start, he could start in the winter somewhere,’’ Manuel said. “But here, if he’s serviceable and if he’s usable, then I’d like to have him. It’s probably selfish on my part, but that’s how I feel.’’

With Igarashi back, the plan is for him and Feliciano to work the eighth and Mejia to work the seventh. Watching Mejia blow away Mark Teixeira Saturday night convinced Manuel.

“Basically, that was the plan all along,’’ Manuel said. “We felt that Igarashi could handle the eighth, and we needed someone to handle the seventh. I wanted to see Mejia pitch in this environment and see how he responded to it, and he did real well.’’

I only hope the Mets stick with this decision and not waver. To bounce him from role to role at 20 could be harmful to his development.

May 23.10: Chat Room, Game #45 vs. Yankees: Santana vs. Sabathia.

Overall, Johan Santana has enjoyed pitching against the Yankees, but what’s gnawing at him is his last one.

Santana, 4-2 with a 4.59 ERA in eight regular-season starts against the Yankees – including 1-2 with an 8.64 ERA with the Mets- gave up nine runs in three innings in a 15-0 loss last June 14 at the Stadium.

“It motivates me,’’ Santana said. “I don’t go crazy about it, but it’s there. I want to pitch against them again.’’

That game represented a career-high in runs allowed until the Phillies hit him for ten runs, May 2, at Philadelphia. Since then, he’s made three starts with no decisions, but a 2.49 ERA. He gave up two runs in seven innings in his last start, May 18, at Atlanta.

Interleague play has not been kind to Santana since joining the Mets as a free agent from Minnesota, going 2-5 with a 5.11 ERA in seven starts.

Santana will be going against C.C. Sabathia, who, beat him in three of four starts while the latter was with Cleveland.

Here’s tonight’s line-up:

Jose Reyes, SS
Luis Castillo, 2B
Jason Bay, LF
Ike Davis, 1B
David Wright, 3B
Angel Pagan, CF
Rod Barajas, C
Jeff Francoeur, RF
Johan Santana, LP

NOTEBOOK: Daniel Murphy went 5-for-5 with three RBI today for Class A Port St. Lucie. He is expected to join Class AAA Buffalo Tuesday. … Former Mets pitcher Jose Lima, 37, died of a heart attack in Los Angeles. He was 0-4 with the Mets in 2006, his final season in the major leagues. … Reliever Ryota Igarashi was activated from the DL and reliever Manny Acosta was optioned to Buffalo.

May 23.10: Maine admits to arm problems; Manuel vindicated.

Is it lying or semantics?

Pitching coach Dan Warthen called John Maine a “habitual liar,’’ two words that could destroy most any working relationship. It remains to be seen whether it will ruin this one, even though Warthen and manager Jerry Manuel have been vindicated for pulling Maine after five pitches last week in Washington.

Warthen’s intent was innocent enough although his choice of words was poor. Warthen meant it in that Maine never admits to his arm feeling poorly.

Even now, when Maine finally admitted something is not right with his shoulder he couched his words.

“There’s a little bit of pain, but what pitcher doesn’t have pain?’’ Maine said. “It’s the nature of pitching. It wasn’t going to stop me from going out there every five days.’’

But, it isn’t pain as much as it is weakness or fatigue in the shoulder.

“There was a little bit of weakness, not that much,’’ Maine said. “I guess they want to get to the bottom of it. What’s the problem, you know? What’s going on back there?

“Something has got to be found, but if everything comes back good, then I’ll deal with it and pitch, if I have to.’’

In the interim, the Mets must improvise.

The current thinking is to use Raul Valdes, who replaced Maine after his five pitch-outing, against the Phillies Tuesday night, followed Hisanori Takahashi and Mike Pelfrey. The thinking of Valdes over R.A. Dickey is because of the left-handed power in the Phillies’ line-up.

The next time Maine’s turn in the rotation would be is a week from today. But, the Mets will jump off that bridge when they get to it.

May 22.10: Chat Room, Game #44 vs. Yankees: Pelfrey attempts to stop slide.

The beleaguered Mets – losers of eight of their last ten games – hope to get better tonight with Mike Pelfrey (5-1, 3.02) going against the Yankees.

Pelfrey is making his third start against the Yankees, against whom he is 1-1 with a 5.40 ERA in 10 innings. In his last start, Pelfrey gave up two runs over a season-high 7 2/3 innings Monday at Atlanta, which snapped a five-game losing streak.

With questions throughout their rotation, Pelfrey has been the Mets’ most dependable starter, and his 3-0 with a 2.61 ERA in five home starts. Pelfrey attributes much of his success for falling out of love with the sinker. He said he was becoming predictable with the sinker.

“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.’’

What hasn’t changed is the Mets’ myriad of pitching questions, beginning with John Maine, who will be examined by doctors Monday for discomfort and fatigue in his shoulder.

Maine pitched to one batter Thursday night at Washington before being removed. Angry for being taken out, Maine has finally admitted to discomfort, but stubborn as he is, said he didn’t think it was necessary to go on the DL.

Raul Valdes replaced Maine and pitched five strong innings. He was so effective, that Jerry Manuel has tentatively penciled him in over knuckleballer R.A. Dickey to start Tuesday against Philadelphia.

The Mets’ offense, save a 10-run explosion Thursday night, has been listless for much of May. It has been a brutal month for David Wright, who was 0-for-4 with two strikeouts. Wright has struck out 23 times since May 8.

Here’s tonight’s line-up behind Pelfrey:

Jose Reyes, SS
Luis Castillo, 2B
Jason Bay, LF
Ike Davis, 1B
David Wright, 3B
Angel Pagan, CF
Rod Barajas, C
Jeff Francoeur, RF
Mike Pelfrey, RP

May 22.10: Don’t count on Mets getting Oswalt.

Just because Roy Oswalt wants out of Houston, don’t go thinking his next stop is Queens. Oswalt has $31 million remaining on this contract through 2011, plus an option, so he won’t come cheaply.

I know what you’re thinking, if they can give more money than that to Oliver Perez, why can’t they give it to a good pitcher such as Oswalt?

They could, but do you really see them spending that kind of money? I don’t, and I don’t see Oswalt waiving his no-trade clause to play for a team that’s in disarray.

Let’s face it, outside of a pitcher’s ball park, what do the Mets have to offer. A listless offense? Perhaps a managerial change? Perhaps a change in the front office? A shaky bullpen?

The Mets aren’t a very attractive proposition right now.

Even so, the Mets still have three holes to fill in their rotation.

After last night, Hisanori Takahashi will get another shot. So will R.A. Dickey. The next time John Maine’s spot in the rotation will come up will be a week from tomorrow. The best guess is it will be Pat Misch.

Bottom line, for immediate help, it will have to come from within.
