It seems impossible, but when it comes to pitching, Marcus Stroman is just a baby, man. “I’m still fairly new to pitching — I just started really pitching my junior year in college,” Stroman pointed out when we talked before a game against the Giants. He was a junior at Duke University in 2012.

Even if you count the first two years pitching at Duke, it’s only six years. Six years might seem like a long time. Six years ago, I decided to take a leap into writing about baseball for a living. Six years is not a long time, at least not to me. I’m still trying to figure out how to arrange my words in the right order, so it’s no surprise that the pitcher is “starting to learn sequences” better now.

And so, as good as the righty starter has been — top 20 by any overall per-inning measure — his latest work, and words, put into focus how he might get better.

If you look at Nick Castellanos‘ traditional statistics, you obviously will notice that something is different. His OPS is nearing 1.000 after messing around in the 700 level before. This was the kind of improvement we were hoping for! The wait is over!

If you look at the next level, things begin to muddy. Basically 40% of the third baseman’s balls in play have fallen for hits, compared to 33% in the past. His walks and strikeouts are about the same as his previously established levels, and his batted-ball spray, in terms of pulling versus going oppo, remain roughly the same, too. He’s added a few fly balls, as he’s cut his grounder rate nearly 40%, so we could call it a little bit of power growth plus a lot of luck, and call it a day.

But we’ve got another level of statistics now, and if we look into those numbers, we see the type of growth that seems sustainable, and points to a small step in approach that may lead to a giant leap in production — even if projection systems usually call for restraint in such situations, even for a 24-year-old.

A a writer, you typically have an agenda when you approach a major-league hitter in the clubhouse. Literally. Even me! I try to keep it open-ended — and avoid the old “can you talk about how important player X is so that I can finish up my piece on him”-type questions — but I still have a (loose!) narrative sketched around some key stats when I step to a player. It’s called research.

Sometimes, the player has an agenda, too. Maybe that’s wording it too strongly. Sometimes, the player doesn’t want to answer your questions and has something else on his mind. That’s better.

That describes what happened when I talked to Josh Donaldson last night before a game against the Giants. He was obviously thinking about the night before, and when I brought up an old conversation about his two-strike approach, and the deception between Zack Greinke and Paul Konerko, he started talking about pitchers not following the rule book.

I let him run with it.

When you’ve got a problem with command, your options seem obvious. You can clean up your mechanics, which is easier said then done. You can focus on throwing strike one. You can move on the rubber in order to move your heat map to a better spot. You can tinker with your fastball selection in case you have better command or outcomes with one of them. You can limit throwing a secondary pitch you don’t command that well. You can throw in the zone more and risk home runs if you miss more middle-middle.

It looks like Seattle’s Taijuan Walker is fighting poor command with a new weapon: throwing a secondary pitch in the zone more often. The best part is that, if it’s the right secondary pitch, command of that pitch is not super important. Tai’s fighting with a new approach to his curveball.

Deep in the bowels of Oakland’s Coliseum, you’ll see Ryan Madson working out with wires strapped to his body. The wires head to a little pack he carries with him, and in that pack is a machine that has helped him recover his career.

The device, pictured here, is the Accelerated Recovery Performance machine, which was administered to Madson by the EVO Ultrafit group in Arizona. The ARP sends electrical stimulation to your muscles much like the stim packs and microcurrent versions out there, but claims to have a proprietary wave form that allows for deeper penetration of the muscles.

The Oakland closer is not alone in believing in the benefits of the ARP machine — many out there tout its abilities to help the body recover and retrain — and yet there are equal shares of doubt about its efficacy.

Just a couple weeks back, Dave Cameron examined the things that should worry us about Dallas Keuchel. He was more nuanced, but we could break it down into three components: lower velocity, fewer calls on the black, and fewer swings. For a guy that had the third-lowest zone percentage in baseball last year, the latter two seem hugely important for his success. So I asked the Astros’ lefty what he’s doing about those things.

Lower Velocity

Asking a pitcher about velocity is a delicate thing. Big increases mean whispers, and big declines mean… whispers of another sort. And then there’s the brutal march of time that fritters away our athleticism, day by day. You walk on egg shells.

But they know their radar-gun readings. And though age should have stolen about a tick from Keuchel, it looks like he’s down more than a tick and a half on the radar gun, from 89.6 mph last year to 88.0 this year. But that’s comparing all of last year to this year’s April, and also ignoring a slight uptick in recent games. If you compare last week’s velocity to last year’s April velocity, Keuchel is only down 0.8 mph, well in the normal range for a 28-year-old pitcher.

Adam Conley is surprising some with his sophomore effort, just by seemingly repeating what he did in his debut last year. His velocity, ERA, WHIP — even his swinging-strike and ground-ball rates — are all about the same as they were in 2015. But he’s different! In important ways.

Late last year, in the midst of a decent debut with the Marlins that saw him hitting 94 mph on the radar gun and shutting out the Mets on their way to the World Series, the lefty starter saw a picture of himself and froze. “I really didn’t like what I saw,” Conley told me a few days before he no-hit the Brewers for seven-plus innings this year. “It didn’t look like what I thought I looked like.”

Maybe the image was something like this one from his start against the Nationals late last season. “I could see in the picture that my front side was gone completely and my foot wasn’t down,” Conley says. “My foot is floating through the air and I’m trying to throw the ball.”

But once he saw that thing, he was convinced. He had to get back to the things he’d heard growing up, when he took the drive to Pete Wilkinson’s camp to work on his pitching mechanics. He had to get away from results-oriented development — “throughout the minor leagues, they would talk about results a lot,” he said — and get back to making sure his process was good.

The effort was two-pronged. He had to make sure he was getting his power from the right places, and he had to make sure his pitches worked together. The results brought him back to where he was, in a more sustainable way, with differences that appear once you look under the hood. And as he describes it all, you start to hear all of the things that we’ve been hearing recently as the new numbers have caught up to the pitching coaches.

I gave Royals’ right-hander Chris Young a bit of an incredulous look — “You’re throwing the slider a ton this year!” He shrugged. Sure. “It’s okay, you can throw it inside and out, and it’s been good. But it moves a little differently depending on where you throw it.”

Young then mimicked the release point when trying to throw a slider inside to a right-handed hitter, and then he showed where the release point might be when throwing it outside to a right-handed hitter. One was straight to the plate, and the other had more side-to-side finish to it.

If you’ve pitched competitively — or, at least, possess more experience than my own, which is limited to throwing a whiffle ball to my kid while he imitates Julio Franco — this may be old hat to you. But to me, it was surprising and also totally logical at the same time. I immediately wanted to know what this looked like.
