Adding a five-time All-Star to the roster seems like a no-brainer as a recipe for success, certain to help a team get to another level. But for Mets manager Jerry Manuel, the expected addition of Carlos Beltran next week in San Francisco after the All-Star break comes with this potential backlash: How can he keep his entire outfield corps happy and productive?

“It will be a tough thing,” Manuel said about seamlessly integrating Beltran and divvying up playing time. “I think a lot will depend on them. It gets now to the point of you have to perform to kind of be out there. I think that’s where we are.

“We’ll sit down and talk with them and let them know what’s to come. We’ll try to map it out for them so they don’t come to the ballpark not knowing whether they’re going to play or not. I’m going to try to give them an advance schedule as to what I anticipate the lineup to be.”

For a while it looked like Angel Pagan’s oblique injury might linger and render this entire conversation moot, but the 2010 Mets’ best outfielder has five hits including two doubles and a homer in his last two games, so it appears Pagan is healthy.

Mets fans have come to expect the worst from the team and its manager when decisions like this one come up. After all, it’s the same club that started Gary Matthews Jr. and Mike Jacobs on Opening Day.

But I’m going to take “you have to perform to kind of be out there” as a glimmer of hope.

This may be inconceivable to many Mets fans and beat reporters, but Jeff Francoeur should lose the most playing time when Carlos Beltran returns. It’s a no-doubter. Shouldn’t even be up for debate.

“You have to perform to kind of be out there,” like Jerry says, and Francoeur has not performed. Not at nearly the same level as Angel Pagan or even the long-befunked Jason Bay.

Francoeur himself said that Manuel’s decision should be difficult because none of the Mets’ current outfielders is “flat-out sucking.” That’s a relative term, I suppose. Francoeur is not flat-out sucking compared to how your average man on the street might suck if tossed into the rigors of Major League play. I could not post a .711 OPS at any level of professional baseball.

But every other starting Major League right fielder can better that rate, and that’s the issue. Among the men who man his position, Francoeur is dead last in OPS. He’s second to last in OBP, last in wOBA and third to last in WAR.

And why shouldn’t Francoeur, a Major League veteran, be given more leeway? Because these numbers are precisely in line with the ones he has posted across his career. This is Jeff Francoeur.

Flashes of awesomeness like the one he had to start the season or his three-week stretch starting in late May are nothing new; they were enough to enchant the Braves into giving him everyday playing time for four seasons. But Francoeur still hasn’t mastered the strike zone, so he is forever prone to the lengthy droughts that have hampered his 2010.

Angel Pagan has been great this season. Straight-up great. Jason Bay hasn’t been himself, but he has still performed a whole lot better than Francoeur. So — and the joke could very well be on me — I’m going to go ahead and assume that when Jerry Manuel speaks about “performance,” he also understands what that means. Pagan and Bay have far outperformed Francoeur. And Carlos Beltran is really, really good.

There should still be playing time for Frenchy, no doubt. With Fernando Tatis on the disabled list, the Mets will need a primary right-handed pinch-hitter. Plus Francoeur has always torched lefties, so he should spell Pagan against tougher ones. And Beltran will need plenty of rest days for his achy knee.

It just shouldn’t come down to an even split for Pagan and Francoeur or equal shares for everyone or anything like that. The Mets’ outfielders have not performed equally.

All the walk-off losses on the road is indicative of an eighth-inning guy. That’s where an eighth-inning guy pitches. It’s basically that simple. If that eighth-inning guy is the guy, he pitches the tie game on the road. At home, the closer pitches the tie game because you get a chance to bat. That’s just the way that works. I mean, that’s baseball.

– Jerry Manuel.

OK. Exhale.

That’s baseball?

The Mets’ absurd and quixotic quest for this elusive “eighth-inning guy” has crippled them all year. It forced Jenrry Mejia into the big leagues before he was ready, Fernando Nieve into an ungodly amount of work, and now Pedro Feliciano and Elmer Dessens into situations they should never face.

That’s not baseball. Not good baseball, at least.

Look: Some teams have an eighth-inning guy. If you have two awesome relievers, great, make one the closer and one the eighth-inning guy. Shorten the games. And yeah, you might be better served using one of them in higher-leverage spots in the sixth or seventh when the starter tires and there are men on base, but whatever. The eighth inning and ninth inning of close games are pretty big spots. By all means, use your two best relievers there.

But if you don’t have some distinct second-best reliever, or hell, even a second decidedly good reliever, holy crap, don’t force it. There’s no need at all to anoint someone “eighth-inning guy” if he’s not cut out for it.

Pedro Feliciano is a valuable bullpen arm who can pitch nearly every day and retire tough lefties with unbelievable reliability. I am a fan of Pedro Feliciano. He is very good at his job.

But he is not capable of reliably getting right-handers out, nor has he ever been. He should absolutely not be facing right-handed hitters with the game on the line.

And look, before you ask: I’m not even certain what I would’ve done there. Presumably Bobby Parnell was unavailable after pitching in three of the last four games, clearly next in line for the Nieve treatment. And Jerry’s not getting much help from the front-office, with his team already man-down and carrying three catchers and a crappy bullpen.

But if K-Rod needs work badly enough to come in with the Mets down one run in the eighth inning Tuesday, why is he not allowed to pitch with a tie game on the line on Thursday? Hell, he was warming up. Is it — heaven forbid! — that a save situation might arise without K-Rod available to nail it down? Because, you know, managing to a pointless stat, that’s baseball.

Also a big part of baseball: Throwing your entire bullpen under the bus when you’ve mismanaged it all season. The Mets aren’t suffering walk-off losses on the road because they need an eighth-inning guy, they’re suffering walk-off losses on the road because they think they need an eighth-inning guy.

Sagiv at Fire Jerry Manuel covered last night’s game with his unique brand of vitriol. Check it out (language furiously unsafe for work).

Tejada had a 10-game hitting streak, but his biggest contribution was on the defensive end. The folks at Baseball Info Solutions tell us Tejada had 19 balls hit to him in double play situations at second base this month.

He turned 12 of them into twin killings, a conversion rate of 63 percent. That’s a significant improvement over Castillo’s 47 percent conversion rate (the major league average for a second baseman is 52 percent).

– Mark Simon, ESPN.com.

Simon uses one stat to quantify something that’s pretty clear to every metric and eyeball in the world: Ruben Tejada is a better defender than Luis Castillo. Castillo’s certainly got experience on the 20-year-old, but Tejada appears able to mitigate his lack of familiarity with the position with his impressive range and excellent instincts.

Thus far, Tejada has not embarrassed himself with the bat, either — no small feat for a player his age in the Major Leagues. It’s still a tiny sample, but Tejada’s .269/.329/.328 line is not terribly far off the league-average .264/.333/.386 mark.

Whether Tejada can keep that up remains to be seen, though it’s not as if his Major League offensive performance is a massive improvement over his respectable Minor League history. But he appears to rely on slapping the ball to the opposite field, so it’ll be interesting to see if the league adjusts to him with a little more exposure.

If he can maintain this performance, though, he should remain starting at second base even if and when Castillo returns. Though Castillo is likely to improve upon his meager offensive line this season and be a better hitter than the rookie, Tejada’s defense makes up for the difference in production.

Castillo has not yet started a rehab assignment and is apparently recovering slowly — in that he can ever truly “recover” — from his injury, so this could be immaterial.

But if it does happen — assuming Jose Reyes’ injury is as minor as the Mets are making it out to be — how will the team handle it if Castillo returns and Tejada is still playing this well? It sets up a fascinating test for a front-office on a recent run of reasonable decision-making. Castillo will have less than $9 million owed to him over the remainder of his contract. Is that little enough for the Mets to stomach cutting him free, eating the sunk cost?

But wait! Castillo is a switch-hitter and a better offensive player and baserunner than Alex Cora. Cora is on the team because he can back up Jose Reyes at shortstop, but Tejada could just as easily slide over when Reyes needs a rest and fill that position more aptly than Cora, with Castillo replacing Tejada at second.

So if Castillo returns and Tejada still appears a better bet to be playing second base everyday, Cora should be the odd man out. But can the Mets cut Mr. Vesting Option himself, the catalyst of all clubhouse chemistry?

I’m guessing no. But they’ve been surprising me since the day Mike Jacobs got cut.

If you ever see me complain about having to go a baseball game for work, please find me and punch me in the face. There is nothing more loathsome than when reporters or broadcasters paid to cover baseball whine about the heat or long games or the crummy press-box food. You’re watching baseball for a living, bro. No one’s saying your job is easy, but don’t pretend you’re so great at what you do that you couldn’t be replaced by someone from the legions who would kill for the opportunity.

I try not to express too much excitement over the awesome aspects of my job here because I fear it will sound like bragging. But it never stops amazing me that I am allowed to do some of the things I get to do. It’s crazy.

I spent two hours this morning in a conference room at a Connecticut country club talking baseball with Ralph Kiner for an upcoming series of web videos. We watched old clips from Kiner’s Korner and used them as jumping-off points for discussions about the sport and its history, plus Ralph’s personal memories.

It was amazing. I don’t want to scoop the videos as I’m hoping you’ll watch when they come out, but Ralph talked about everything from train travel to pitch counts, and even got into a tiny bit of his history of dating celebrities. Plus he mentioned how batting average is overrated because it doesn’t include walks, just in case his .946 career OPS wasn’t enough to endear him to sabermetricians.

It’ll make for quite a few videos, so I had to film a bunch of opens and introduce him many times. I asked him if being introduced as “Hall of Famer Ralph Kiner” ever got old, and he said, “how could that ever get old?”

It was cool.
