As in years past, we'll use the Make-the-Mets-O-Meter this spring in an effort to divine the Mets' Opening Day roster. The Mets have a ton of players in camp this year including 16 non-roster invitees. By definition, NRIs are less likely to make the team than their 40-man-roster counterparts. The selection of any NRI for the Opening Day roster will require a concomitant 40-man roster move, which then requires that someone be exposed to waivers, and so forth. Given two identical players, the one who is already on the roster has a huge advantage.

Here, then, is the first Make-the-Mets-O-Meter of the spring. Pitchers today, hitters tomorrow.

Player		Comment
Manny Acosta, RHP		Acostalypse has a pretty good chance of making the team.
Manuel Alvarez, RHP		Struck out 10.9 and walked just 1.1 batters per nine (9.50 K/BB) in 47 innings with Double-A Binghamton as a 24-year-old last season.
Pedro Beato, RHP		Has allowed a run in two spring innings so far. The Mets plucked him from the Orioles in December's Rule 5 draft, which means they have to keep him on the active roster all year or offer him back to the O's for $25k. That fact alone gives him a small advantage over the other righties in camp. Being a local Brooklyn kid doesn't hurt, either.
Boof Bonser, RHP		He's a non-roster invitee which puts him at a disadvantage before we even get started. Then again, this and this.
Blaine Boyer, RHP		Very unlikely that Boyer will make the Opening Day roster. Effective against righties but not much else.
Taylor Buchholz, RHP		The Mets signed him to a major league deal this offseason so it's unlikely he doesn't make the team. I've included him here just in case.
Tim Byrdak, LHP		"The Byrdman" is a serious LOOGY, excelling against LHB and struggling against RHB. That he throws with his left hand can only help his chances.
D.J. Carrasco, RHP		The Mets gave him a two-year contract this offseason to pitch out of the big league bullpen. He'll be on the team.
Dillon Gee, RHP		Gee had a nice debut with the Mets in September, but unless a few guys get hurt he'll lose the numbers game this spring.
Ryota Igarashi, RHP		Struck out two in an inning of work on Monday, but he also gave up a two-run home run to Mike Morse. He cleared waivers earlier this offseason so the Mets would have to put him on the 40-man roster if they want him on the big club for Opening Day.
Jason Isringhausen, RHP		Tossed a scoreless inning on Monday and got three ground outs in the process. Tried out his changeup and hit a batter with it. He's a good story, though.
John Lujan, RHP		Struck out 45 and walked just 12 in 37.1 innings with Triple-A Buffalo in 2010. Appears to be a ground ball pitcher, too. He'll turn 27 in May.
Jenrry Mejia, RHP		Sandy Alderson isn't like to repeat Omar Minaya's mistake with respect to Mejia. The Mets' top pitching prospect will begin the year in the minor leagues.
Pat Misch, LHP		Being left-handed and grounder-prone makes him a better option than Dillon Gee. Like Gee, however, Misch will need some injuries to get a shot out of the gate.
Michael O'Connor, LHP		Pitched a scoreless inning on Monday and would require a 40-man adjustment to make the Opening Day roster. Then again, he's a lefty.
Oliver Perez, LHP		Har, har! I'm delighted that Perez is even on this list, but if he continues to drop three-walk, four-run outings this spring like he did this weekend he could find himself out of a job.
Armando Rodriguez, RHP		Rodriguez had a great season as a 22-year-old with the Low-A Sand Gnats last season, striking out 152 in 146 innings as a starter. He's not likely to make the big club this spring.
Tobi Stoner, RHP		Still has a great name, but the Mets dropped him from the 40-man roster this offseason and I can't imagine they're in any rush to put him back on it.
Taylor Tankersley, LHP		Gave up three runs in an inning on Monday including a two-run shot to Mike Morse. Another mediocre lefty competing for Pedro Feliciano's old spot in the bullpen.
