Same deal as yesterday, except only one of the two games the Mets played. Specifically, the one I watched:

The Mets lost this one to the Marlins in the 10th inning, 3-2. It was heartbreaking, but mostly for Keith Hernandez, who pretty obviously wanted to get out of there and was hoping they’d just call it a tie after nine.

Ralph Kiner was in the SNY booth, and Ralph Kiner is awesome. He told Keith Hernandez, “time stops with you,” which made me hope Ralph knows something about Keith that I don’t yet. Perhaps Keith Hernandez has the power to control time, like Zack Morris or something.

Marlins’ reclamation project Hayden Penn has some crazy facial hair. It’s like a modified Colonel Sanders, only blonde — not white. Just calling it a mustache and soul patch wouldn’t be doing it justice; the mustache is real thick, almost hanging down over his lips in the Nietzche fashion.

On the Mets side of things, Jenrry Mejia was clearly the most impressive part. See below for more details, and keep in mind that all this means very little.

Jon Niese was pretty damn decent, too. He did allow three hits and two walks, but none of the hits were terribly well-struck, and he struck out five batters in his 2 2/3 innings. He threw his cutter a ton, which was cool, and still has all that movement on his curveball.

SNY had a gun going today, so we got some early returns on Ryota Igarashi’s fastball. He was sitting in the low 90s and pitched pretty well, except for an near-inexplicable home run to Emilio Bonifacio — Bone Face, to some — who only has one home run in 722 Major League plate appearances. Luckily, this one doesn’t count for anything.

Mike Hessman is huge. He looks like he can smash a ball. I really have to get to Buffalo this season to see him in a lineup with fellow Quad-A masher Val Pascucci. Also, why isn’t Pascucci in the big camp?

Kai Gronauer, a German dude who I thought was only in camp because teams need lots of catchers in camp, played DH today. And he got a hit. Bully for you, Kai Gronauer. Or as they say in German, herzlichen glückwunsch.

I don’t actually speak German. I just looked that up. Come tell me I’m wrong now, Internet.

Wilmer Flores had a hit, a single up the middle. So that’s cool.

Bobby Parnell gave up the decisive blast in the top of the 10th, a two-run opposite-field homer to Marlins’ prospect Michael Stanton. Stanton has a buttload of power, and also two names. I’m not entirely clear on the mechanics of this, but his baseball-reference page calls him “Giancarlo Cruz-Michael Stanton.”

If I had to pick between those names, I’d go with Giancarlo Cruz, mostly because I once attended a game that Mike Stanton the lefty reliever lost without even throwing a pitch. Serious. I was in Milwaukee, and Stanton was making his Nationals debut, I believe. He came in to a tie game with a runner on third in the bottom of the ninth. He promptly balked, forcing in the winning run. Only time I’ve ever seen that happen.

Anyway, it seems as though the Mets’ book on this Michael Stanton involved not throwing him any fastballs over the plate. Pedro Feliciano made it work for him, striking him out on three straight changeups in the dirt.

Parnell hung a breaking pitch over the middle and Stanton made him pay, jacking a line drive the opposite way and putting the Marlins ahead for good.

Luckily, it doesn’t matter even a little bit.

So I’ve written a whole bunch about how I don’t think Jenrry Mejia should be in the Major League bullpen this year without having ever really seen the guy pitch.

Now that’s changed, and whoa, nelly.

Mejia just finished off 2 1/3 perfect innings in a meaningless game against the Marlins. He struck out four batters and yielded two grounders to short and a lazy fly ball to left.

By my count, Mejia threw 19 fastballs, topping out at 96 miles per hour on SNY’s gun. Most of them sat around 94 or 95, and I don’t think any were slower than 93. Of the 19 heaters, 17 were strikes — either swinging or called.

He threw two of what I think were changeups in the high 80s. One was a called strike, the other missed the inside corner.

He also threw four curveballs. They appeared to move a lot, but a couple of them missed pretty wildly. Three of them were balls, one was a called strike.

This is a tiny sample of course, and Mejia was hardly facing the Marlins’ Opening Day lineup, but, well, damn. I still obviously don’t think he should be anywhere near the Major League roster anytime soon, but when you see a 20-year-old rely mostly on one pitch to completely beguile big-league (or close to big-league) hitters, you can start to understand what all the fuss is about.

Fire up the hype machine.

So Jose Reyes’ blood test yesterday revealed a thyroid imbalance and he is traveling to New York for further testing.

This sucks.

This sucks for the Mets, it sucks for Mets fans, and it sucks, most of all, for Jose Reyes.

I don’t know anything about any thyroid imbalance beyond goiter, but I know plenty about undergoing medical testing when you feel more or less healthy, and I can attest that it’s awful. You feel fine, but you’re treated like a sickly person. They put you in a paper-thin gown and poke and prod at you with their instruments, then talk about you in a lingo you don’t understand as if you’re not standing right there. It’s humiliating and terrifying. And yesterday, Jose Reyes thought he’d be playing baseball today.

Maybe this is nothing, and for all I know it’s minor enough that it can be easily treated with medicine or therapy or something and this will just be a tiny little blip on Reyes’ MVP-caliber season in 2010.

But it sure does suck right now, because everything about Reyes since Mets’ camp opened had been so glimmering, so overwhelmingly positive. And now once again, due to no fault of anyone in particular, Reyes’ health is a big foggy mystery.
