Per at-bat, Manny Machado is better this year than he was last year. That’ll happen with a 24-year-old. Or at least that’s what people tell me, I don’t remember those halcyon days myself. What’s most interesting, of course, is how he’s done it. You can tell that he’s hitting for a bit more power by hitting more fly balls, and that he’s improved against breaking balls. That much is on the player pages. But was it the result of a mechanical adjustment, or an approach adjustment? Ask the player, and the answer is yes. And no!

“I haven’t really changed anything,” the Orioles infielder said recently of his swing. “You get a little smarter with the pitches they’re going to throw to you, what they are trying to do to you. Try to look more for a pitch you can drive.” When pushed on that particular subject, he admitted what most hitters would probably admit if they were being honest. “I’m sitting dead red. Looking for a fastball down the middle, more or less.”

“What’s my power, what’s my cookie?” he added with a smile. As for his answer, it does appear as though the fastball up has rewarded him with the best results. He’s been more aggressive on the fastball out over the plate and that’s resulted in more fly balls and power. Here’s his swing rate on fastballs last year (left) and this year (right).

Sitting on that high fastball has made the low pitches look less attractive — the same thing Adrian Beltre found when he started looking for the high fastball — and that has, in turn, dampened Machado’s ground-ball rate on fastballs.

We first encountered Joe Musgrove’s one-seam sinker around the All-Star break, when the Houston Astros right-hander was kind enough to show us the grip before his appearance in the Futures Game. I’d never seen a one-seam grip before, unless you count the one Zach Britton showed us. While we could spot glimpses of the sinker in the Futures Game and in his minor-league games, it wasn’t until Musgrove came up and started pitching in the big leagues that we could truly put his pitch in the context of other big-league sinkers. It’s weird.

If you want to know the most insidious part of my job, it’s deciding what to write about when. Some of the decisions aren’t that crafty — sometimes I have to sit on a Kenta Maeda interview because August just wrote him up, for example. Other times, it’s a small move, like publishing a piece about a pitcher on the day he pitches instead of the day before.

But there are times that make me feel icky. Like the time I talked to Sean Manaea in May and never wrote it up because I felt like there were topics out there that might get more interest. And because I was waiting for a good stretch of ball from him. Well, congratulations to me for being a bad person — Manaea has a 2.84 ERA with 38 strikeouts and just eight walks in 44.1 innings since July tenth. Time to transcribe, you awful, awful dude!

The good news is that we can now check in on the things that Manaea was working on back then and see how they worked out. Welp. If I’d been less honest now, I could have said I planned this all along. Oh well, now you know more about me. Time to know more about Manaea.

In the second half of the double-header between the Twins and Astros today, Chris Devenski will take the mound for the Astros. He owns an 80 mph changeup and a 92 mph fastball, give or take some ticks, and that differential is the fourth-biggest one among starting pitchers since 2014. That fact alone should make his changeup a great one when it comes to whiffs.

We’ve known for a while that movement and velocity differential are important to a changeup, but seeing as how the relatively ineffective John Lamb possesses the league’s second-best differential — and because the changeup works, in no small part, because of its relationship with the fastball — it seems fair to wonder, as someone in my chat did today, if a changeup which features too great a velocity differential might also suffer from ineffectiveness. In theory, an 80 mph changeup might look the nothing like a fastball. And if that’s the case, how could it fool the batter?

Imagine being Hyun Soo Kim. You’re signed by the Baltimore Orioles to a deal that’s on the small side by American standards, the kind of deal that comes without fanfare or breathless video crews. You’re optimistic about your chances of succeeding in the majors. You spend your spring training calmly adjusting to a new league and country — and then, suddenly, you’re in the middle of a maelstrom when you opt to refuse a minor-league assignment, a right you negotiated into your contract for a reason.

All that might be firmly in the rear-view mirror by now — “I consider spring training in the past” said the Orioles outfielder before a game against the Athletics — but that sort of backstory would make any of us a little uncomfortable. The good news is that the outfielder finally made all of those adjustments, on his own time, and is now getting comfortable in this new situation.

Padres reliever Ryan Buchter has been around — playing for five organizations since 2008 — which really only means that teams haven’t agreed on his value. For every team that’s passed on the left-hander, another onehas seen something. That’s the life of a reliever, sure, but this one is doing well right now, and took a while to find his way to San Diego.

The lefty is well aware of his strengths and weaknesses in the minds of those organizations, since he heard different directives from each development team. He’s a fastball guy who doesn’t feature great secondary pitches, those coaches have told him, if not in those exact words. But along the way, Buchter has developed his own view on what makes his style effective. And it’s not just his elite spin rate.

Marcus Stroman ended June with a bloated 5.33 ERA that was mostly deserved, so he went back to the drawing board. He’s since had an ERA two runs lower, once again deserved, since he changed things in early July.

After a good start in early July, he made general reference to some adjustments after the game, and Shi Davidi went and asked pitching coach Pete Walker for some specifics. So we know some of what Stroman did to recover. He cleaned up the delivery, he moved his hands, he changed his release point, and he altered his pitching mix. It’s the kind of stuff pitchers do to bust a slump.

The most interesting thing might be where he learned these things, though. Who knows when he picked them up from the Red Sox lefty, but these adjustments have made Stroman a bit more like David Price these days. Even if Price is struggling a bit, you have to count that as a good thing compared to where Stroman was earlier this season.

Try to imagine the ideal sinker. What do you see? Probably a pitch that sits in the high 90s, right? And features tremendous sink and fade. And induces ground ball after ground ball. And, because it’s being thrown with max effort, probably one coming out of a reliever’s hand, right?

If you’re imagining a pitch that meets all four of those criteria, you probably see Blake Treinen throwing it. Or Sam Dyson. Or Zach Britton. If not, you should be.

If you limit the pool of commonly used sinkers to those which average 94 or more mph and then sort for sink, those three names soar to the top. And each gets to that movement in a different way.
