So Pedro Feliciano wants to be the Mets’ eighth-inning guy. Everybody wants to be the Mets’ eighth-inning guy. We all want to anoint the new eighth-inning guy.

OK, let me start right off by reiterating that I think the whole need for a specific, dedicated eighth-inning guy is silly. Again, there’s little evidence that even having a one-inning closer helps teams finish out games more successfully than they did in the time before the trend started up in the late 80s:  “In the 20 seasons since LaRussa’s brainstorm, teams holding late leads have won at about the same rate they did in the 20 seasons before.”

Regardless, looking at Feliciano specifically, there may be some merit to the concern voiced by SNY’s Gary Cohen, among others, that Feliciano is too valuable to the Mets in his current role — as a middle-inning lefty specialist — to consider moving to a setup position.

Fangraphs charts Leverage Index, “a measure of how important a particular situation is in a baseball game depending on the inning, score, outs, and number of players on base, created by Tom Tango.” A pitcher’s average Leverage Index when he enters a game is called his gmLI.

According to that stat, Feliciano entered games in, on average, the fourth highest-leverage situations of any Met reliever. Ahead of him were Casey Fossum, whose gmLI was certainly driven up by a tiny sample, J.J. Putz and Francisco Rodriguez. Feliciano finished third on the team behind Luis Ayala and Billy Wagner in 2008.

Turning to the list of 2009 Major League leaders in gmLI, the highest-ranked non-closer is Seattle’s Mark Lowe, decidedly an eighth-inning guy — 50 of the 71 1/3 frames he tossed last season were that game’s penultimate one. The next, Jeremy Affeldt, had the eighth inning account for 36 2/3 of his 62 1/3 innings.

The next two pitchers on the list, though, were Matt Thornton and Phil Coke, a pair of lefties, neither of whom threw more than half his innings in the eighth (although both pitched plenty in that frame).

So what does that mean? Not a ton. Relief pitchers traffic in small sample sizes, and I guess the moral of the story is that though eighth-inning guys tend to enter the game in pretty high-leverage situations, lefty specialists often do too.

Putz, in his short stint of full health, may have entered games in more important situations than Feliciano on average, but no setup man that lasted the year entered games in tougher spots than Perpetual Pedro. And by situational wins, Feliciano was the top pitcher on the team.

There’s no doubt, then, of Feliciano’s value to the team in his familiar role. He might be slightly more valuable as the elusive eighth-inning guy, for sure, but only if he could handle it.

And therein lies the rub. There’s been some talk of Feliciano’s developing cutter, and Feliciano seems earnest in his desire to use it get righties out. Good. He should want to be the best pitcher he can be, always. He’s a professional athlete.

But Feliciano was working on new strategies to get righties out last offseason, too. And righties responded with a .264/.365/.486 line, pretty similar to the .272/.364/.425 mark they’ve tallied off him across his career.

Feliciano’s long been one of my favorite Mets, so I’m rooting for him to succeed in any role. Maybe that cutter will work for him, and then, yeah, he’ll be ever so slightly more valuable to the Mets as a setup man than he was as a lefty specialist.

I’m just not sure it’ll work out that way, though.

With Opening Day now a week away and with little else to write about, I’m going to attempt to preview the 2010 Mets, position by position, over the next seven days. Or maybe do a few posts like this one and then run out of steam. We’ll see.

I’ll start with starting pitchers, because starting pitchers have “starting” right there in their description, and because pitchers are “1” in the lineup card. I’ll end with relief pitchers, even though they’re also technically No. 1 in the lineup card, because we’ll have a better sense of who they are by then.

The format will be whatever the format is on this post. I’m going to figure it out as I go. That’s jazz, baby.

The starting pitchers in April: Johan Santana, Mike Pelfrey, Oliver Perez, John Maine, Jon Niese.

Overview: Yesterday, during WFAN’s coverage of the Mets’ Grapefruit League game, Wayne Hagin lamented the team’s need for a pitcher like Chris Carpenter, who could do to the N.L. East what Carpenter did to the Central last season.

“HELLO!?” – Herm Edwards.

Now, look: Carpenter went 10-0 against the Central last year, and that’s pretty nuts. But few pitchers in the Major Leagues are as qualified to dominate opposing hitters as the one fronting the Mets’ rotation. Johan Santana, assuming health, is not the problem.

Behind him lay question marks that have dotted just about every Mets season preview before this one: Pelfrey, Perez and Maine.

Color me slightly more bullish than most about the prospects of those three. Pelfrey, as noted earlier this offseason, was more a victim of the defense behind him than the demons inside him in 2009. He has been hit hard this Spring, but he has been throwing more breaking balls — something that should help him stop relying on Luis Castillo’s (complete lack of) range for groundball outs.

I’m mildly concerned that a more varied arsenal could make Big Pelf more vulnerable to injury, but assuming Jose Reyes regains most of the range he had before his hamstring injury, Pelfrey should bounce back from his rough 2009 as more of those groundballs bounce into the gloves of able defenders.

Perez enters the season to about the lowest expectations of anyone ever making seven figures not named Gary Matthews Jr. (or Andruw Jones, or maybe Barry Zito. OK, there are a few, but you get the point). It’s becoming increasingly clear that he’s not Sandy Koufax, no matter what Scott Boras says, but thanks to either a return to health or his conditioning program or new-found focus upon his first wedding anniversary, his velocity appears to be back to its 2008 levels.

If the results follow, the Mets will have a wild and frustrating but ultimately league-average middle-of-the-rotation starter in Perez. It’s annoying, but the Good Ollies and the Bad Ollies balance out and make for Just OK Ollie.

As for Maine? Well, I’m a little concerned about Maine. Not about his couple of shaky Spring Training outings or his talent — he’s got that, I think — so much as his ability to stay healthy. Maine has pitched progressively fewer innings in each season since throwing 191 in 2007, and the vagaries of his “shoulder weakness” last year are at least a bit concerning. I’ve speculated before that Maine might have flourished under Rick Peterson, noted for his expertise in biomechanics, but what do I know?

I know this: Maine’s strikeout rates have plummeted nearly as quickly as his innings totals, which is concerning. That could be a whim of the reasonably small sample of innings he pitched last season, but it could mean whatever Maine was using to fool hitters so effectively in 2007 isn’t doing the trick anymore. The velocity on his fastball has remained static and he has thrown a very similar mix of pitches, only less effectively. It could be the injuries, but it’s troublesome regardless. I’m rooting for the guy, but there are red flags all over the place.

The fifth guy, Jon Niese, I like. This I’ve covered.

The starting pitchers in September: Santana, Pelfrey, Perez, Niese and Nelson Figueroa.

Why’d I put Figueroa there? Just a guess. Trying to pick what will happen in September in March is a fool’s errand, and there’s a reasonable chance Figueroa is not even on the team next week, no less six months from now. Consider his name on that list as a stand-in for whatever fifth starter/long-man/fill-in guy they settle on when one of their starters gets injured or proves ineffective, assuming Jenrry Mejia has either hit his innings limit or been made a reliever.

I’m guessing Maine will be the starter that doesn’t last the year based on the red flags listed above. Pelfrey has been a horse for the last two seasons, Perez will have to suck really hard for the Mets to give up on his contract, and Niese’s only major injury has been the freak one he suffered last year.

There’s also a solid chance the Mets go out and trade for a starter if they’re in contention near the trade deadline and one or more members of their rotation is hurt or performing poorly. But we’ll cross that bridge when we get there.

How they stack up: I always think it’s a bit silly when, before every postseason series, newspapers run down the teams position-by-position to determine which team has the advantage where, because it doesn’t work like that. Derek Jeter isn’t facing Jimmy Rollins in the World Series, he’s facing the Phillies.

But I’m doing that here because it’s easy and I’m already 900 words deep into this post and I need to find a quick way to wrap it up. Jazz, like I said.

The way I see it, the Mets’ starting rotation is probably the third best in the division, behind the Braves and Phillies and ahead of the Marlins and Nationals. (Ooh, bold stance Ted!) I came to this conclusion via an incredibly complex scientific process which is far too complicated to detail here.

Next up: Catchers, which won’t take nearly so many words.

Bob Ojeda also doesn’t seem to think Jenrry Mejia should be in the Major League bullpen:

Q: Do you think Jenrry Mejia is major league ready?

A: I am a big believer in you can’t get by with one pitch. When I was [in Florida] earlier in spring training, his other pitches were coming along, but the fastball is the only pitch he can depend on. And if there is a day when that fastball doesn’t show up, then he would have no plan B.

So there’s that.

Shamik reminds me of probably the coolest thing about Jon Niese: He was born the day the Mets won the World Series in 1986.

And check this out: Josh Thole was born the day of the 1986 Mets’ ticker-tape parade. (Also, that is a hilarious Wikipedia find.)

After they dropped the first two games of that Series to the Red Sox at Shea, the Mets had an off-day on Oct. 20. In South Carolina, Reese Havens was born, and then the Mets took four out of the next five to take the championship. Coincidence? Yes. But still.

If that’s not enough to blow your mind, chew on this: Brad Holt was born when the Mets and Astros were tied at two games apiece in the NLCS that year, right before the Mets took a pair of marathons, the latter prompting the epic and notorious flight from Houston.

Also, draw your own conclusions here, but Captain Kirk Nieuwenhuis was born on Aug. 7, 1987, just a little over nine months after the conclusion of the ’86 series.
