OK, so we learned yesterday that several Major League teams are interested in Angel Pagan.

The White Sox, it has been reported, are looking for a center fielder and a leadoff hitter and would prefer to fill their offseason needs with trade acquisitions over free agents, since they can’t add much payroll.

The Mets, we know, need starting pitching depth and could look to fill that need via trade.

The White Sox, meanwhile, have Jake Peavy, Mark Buerhle, Gavin Floyd, John Danks and Freddy Garcia set to be in their rotation next year.

Beyond that, they have 26-year-old Carlos Torres, who started five ineffective games for their big-league club last season but dominated Triple-A.

I don’t think Torres is enough to get a deal done, even if the Mets severely undervalue Pagan due to his mental hiccups. So maybe the White Sox throw in a member of their reasonably deep bullpen, like, I don’t know, say D.J. Carrasco.

Carrasco fits the mold of former Mets’ bullpen targets in that his success appears to be unsustainable based on his high WHIP, plus he brings the Jorge Sosa factor of experience pitching in many different situations.

Is that a reasonable deal? Angel Pagan for Carlos Torres and D.J. Carrasco? I’m not asking if you’d do it — I wouldn’t — only if it seems like something that could happen.

And for kicks, I’ll put it this way, with appropriately vague language:

The White Sox are looking for an inexpensive center fielder and leadoff hitter and could be interested in Angel Pagan. The Mets would likely seek pitching depth in return, possibly in the form of Triple-A righty Carlos Torres and versatile reliever D.J. Carrasco.

OK, so I’m being a little hard on Henry Blanco. By all accounts, including Driveline Mechanics’ system for evaluating catcher defense, he’s a good defensive player. Plus, for whatever reason, he has posted his career best single-season OPS+ totals in the last two seasons (with limited at-bats, mind you) at ages 36 and 37.

Essentially, if you’re committed to signing a 38-year-old catcher, you could do a whole lot worse than Blanco.

In fact, if it was clear the Mets were signing Blanco as a defensive replacement, veteran mentor and occasional right-handed platoon partner for Josh Thole, I’d be all for it.

I recognize that Thole needs to improve defensively, but it’s not like he was terrible behind the plate in his limited time last year. And I’d guess, offhand, that Thole’s bat could at least play to the Major League average for catchers — a .254/.321/.396 line last year — while saving the Mets money to spend elsewhere.

But by all accounts, Blanco is not joining the Mets to caddy for Thole, he’s joining them to back up the free-agent catcher they ultimately sign — likely Bengie Molina.

So I apologize for misdirecting my hostility. It’s not Henry Blanco’s fault the Mets signed Henry Blanco, and Henry Blanco is probably still a decent backup catcher.

That’s all he is, though. He’s certainly not likely to get any better, and it continues to bother me that the Mets rarely seem committed to finding bench guys who might become more than that.
