So, you’ve just called up a super-prospect infielder and you’re wondering, “What can I expect from Gleyber Torres?”

The Yankees promoted the 21-year-old Saturday after a torrid start to the season with the RailRiders. Though we only got to see 37 games of Gleyber in Triple-A, he was certainly impressive, slashing .323/.401/.477 and putting himself on the list of the best-of-the-best to come through Moosic.

Gleyber the hitter

This is the reason Gleyber is going to be the youngest position player to make his MLB debut with the Yankees since Derek Jeter (h/t Katie Sharp). Torres is the purest definition of a hitter. He uses all fields. He hits for average. He has power. He makes contact. He takes walks. But as RailRiders manager Bobby Mitchell has keyed on recently, Gleyber’s IQ at the plate really stands out:

“He has always known the strike zone really well. He always has gotten pitches to hit, which is huge. I think as a hitter, at a young age, sky’s the limit for him. If he just stays within himself, goes up there, plays the game the way he knows how to play it, stay relaxed — but it’s not easy to play relaxed all the time up there when you first get up there — but I’m sure he’ll be fine. I’m sure the guys up there will make him feel wanted and part of the team, because that’s the way they are. And he’ll fit right in. So, I think that’s a big thing for him.” — Bobby Mitchell after Saturday’s game

Mitchell really likes how Torres reads pitchers and says he has an innate ability to detail pitch-by-pitch how they attack him. He’s noted how Gleyber has a knack for filing that information away, being able to go back to it when he faces that pitcher again. (Just like when he matches up against Nationals starter Erick Fedde).

He still wants to learn, too. Like in the RailRiders’ second game of the season against Syracuse. Torres homered in earlier in the game — his first hit of the season …

Later in the game, however, Torres had a chance to do some real damage. Ninth inning, RailRiders trailing by one run and runners on second and third after a sacrifice bunt. Syracuse easily could’ve avoided Torres, pitched around him and sent him on to first base. But Torres helped out the Chiefs, expanding the zone and over-swinging at a couple pitches to fall behind in the count, then bounced a ball right to the third baseman, who cut down the run at the plate.

The next day, Torres said he watched video of his at-bat after the game and saw his mistakes. He also saw Syracuse consistently working the outside part of the plate against him.

He was locked in after that, and followed up that bad AB with this game:

It’s been interesting to see how teams try to attack Gleyber. Syracuse worked him away, but he adjusted to that pretty easily. A lot of teams have tried to get him to chase high fastballs when he’s behind in the count, but outside of opening night (when he struck out three times), he’s able to lay off those. In this last series, Toledo tried to get him up and in, but their pitchers could never really find the sweet spot they were looking for.

Watch Gleyber for a few games, and you’ll pick up on this pretty quickly: His hands are amazing at the plate. It’s where his natural ability really shines through. They’re so quick and quiet and relaxed and smooth and controlled. And quick. He gets the barrel on the ball with ease and the ball jumps off his bat. I don’t know why — their swings don’t look similar in the least bit — but Gleyber reminds me of Mookie Betts, in the sense that he’s going to hit the ball wherever it’s pitched, and he’s going to hit it hard.

It’s fun watching him take batting practice, too, because he approaches it like a pro. He starts by driving everything to right field, but by the end of the session, he’s launching balls over the fence in left. And I’d plan on him visiting the short porch in Yankee Stadium quite a few times.

“He was a little rusty coming into spring. He didn’t realize it, I don’t think. He’s just gotten through that. The playing time’s really helped him during spring, and then now. He’s healthy, which is great. There’s no issues. He just has kind of gotten his timing back a lot. Seeing the ball good, obviously. I was impressed the way he hit some of the offspeed pitches to the other way. Today, he did a good job of playing baseball, getting the guy over to third. That’s the kind of stuff that wins ballgames. He’s just got to keep doing what he’s doing. And I think through the experience of being up there, he’ll just get better and better.

“I loved telling Gleyber (he was promoted) because I had him two years ago, I had him last year a little bit. He’s matured the last couple years into a big leaguer. He’s a big leaguer now, but he still can get so much better. Lot of times I say (Mark) Trumbo or somebody like that. He was a big leaguer in the making, is what he was, when I had him. And that’s what (Gleyber) was, but now he’s a big leaguer and maybe he’s an all-star in the making. Hopefully.” — Bobby Mitchell

Mitchell also said he’s been impressed with improvements Torres has made with his base running.

Gleyber the fielder

Gleyber is a natural shortstop — and a good one at that — but that Didi Gregorius fellow probably has that spot locked up in the Bronx for a while.

So, he’s been learning second and third base the last couple seasons. After a stretch of seven straight starts at third base this year, Torres has now manned the hot corner more times (23) than second base (13) in his career. Don’t read too much into that though. My opinion: Torres is still a better second baseman than a third baseman, and the RailRiders sort of altered his fielding rotation to get him more of a crash course at third.

He’s solid at third, but if Gleyber’s youth/inexperience ever shows up, it’s in the field. He has two errors this year (one at shortstop, one at second) and one was on an unnecessary throw behind a runner. One game last season, when he was playing third base, he failed to keep a bouncer down the line in the infield, and then-RailRiders manager Al Pedrique noted he should have at least knocked it down. But those instances are few and far between. Gleyber has all the tools to be a solid defender in the bigs.

Gleyber the Gleyber

Lastly, Gleyber the guy. Teammates raved about playing with Torres. He became target of some playful ribbing recently, with what seemed like a new media outlet coming to get a one-on-one interview with him every other day. At the RailRiders’ welcome dinner before the start of the season, guys joked about staying away from Gleyber during an autograph session so they could avoid what was sure to be a long line of fans near his station.

“It’s amazing. I remember the feeling myself, and it’s just like nothing else. I’m, obviously, unbelievably happy for him and I love being around him. He’s a great teammate, great guy so, couldn’t be happier.” — Kyle Higashioka

“It’s awesome. I don’t think anybody (in the bullpen) really processed it out there when it happened, and then we kind of let the game play on and we’re like, ‘Oh man, this is his chance!’ Seeing a young stud go up that deserves it, that’s why we all do it. So, we’re all excited for it.” — Brady Lail

Mitchell said he thought it was important that giving Gleyber the news about the promotion was more than just a face-to-face moment. He wanted to share it with Gleyber and the team at the same time. They gave him a round of applause.
