The first time I met Dodgers slugger Cody Bellinger, we didn’t have a lot of time, so I just shook his hand and said that I’d seen him enough to think “you swing really hard, every time, don’t you?” He smiled. “Always been this way.” And that part remained true when we reconnected. But he also opened my eyes to the parts of his game that were molded along the way.

The first coach that Bellinger had was his father. Clay Bellinger got some time with the Yankees earlier this century and coached his son early on. But once the son signed with the Dodgers, the father’s advice receded to “little tips and pointers.” His dad’s a firefighter now, in Gilbert, Arizona, and so he’s a little busy with his day job.

And the son had professional coaches. When he first arrived in pro ball, though, the focus was on staying afloat. “When I first signed in [2013] and Rookie ball in ’14, I wanted to learn how to hit first,” Bellinger said before a game against the Giants. “I was so young — I was 17, 18 — I didn’t worry about power at all.” You can see that there was something different about Bellinger back then.

Those professional coaches largely left him alone that first year, but going into High-A Rancho Cucamonga, they saw an opportunity. “Going into Rancho, they told me it was hitter friendly, so they made some adjustments to my swing. Damon Mashore helped me out,” Bellinger remembers. “I created a little bit more of a consistent path to the ball, just to backspin the ball. I never knew how to backspin balls before.”

A few years back, I was sure that throwing too many breaking balls was bad for pitchers’ arm health. I wasn’t alone — there was some decent research backing up that hypothesis. As the methods for examining the question have become more refined, however, and further work has been conducted on the matter, it looks like we’ve found that it’s not so much breaking balls as velocity that most directly affects arm health.

Perhaps teams have been on the same journey, because curveball usage — and breaking-ball usage, in general — is up to heights we haven’t seen before.

Breaking-ball usage has increased. That said, the uptick has been slow and gradual. Perhaps too slow and gradual. Maybe we should be pushing it.

Round bat, round ball, traveling in different directions: the eight-word story of hitting really captures some of the difficulty of that practice. When you get into the art of choking up — moving the hands up the barrel and shortening the bat — you uncover a whole world of players attempting to address that difficulty. David Kagan examined the physics of choking up today at The Hardball Times. Here, we ask the practitioners what they think. It turns out, the players serve up some conventional wisdom, but also some insight into the reasoning behind the practice.

Over the course of the last week, the Dodgers placed four players on the disabled list, most in baseball. Andrew Toles, with his torn ACL, would have gone on the DL in any other year, and that might also be true for Adam Liberatore and his strained hamstring. But Kenta Maeda (tightness in hamstring) and Brandon McCarthy (sore left shoulder) are dealing with less debilitating issues. They might not have been placed on the DL if not for the flexibility allowed by the new 10-day option. But has that flexibility really created an explosion in DL usage? What ramifications would that have on the game?

I’ve always loved Bronson Arroyo’s leg kick. There’s some whimsy in it, is maybe why. At the very least, it represents a different mechanical approach than one finds elsewhere in the league.

Turns out, there are reasons against flinging the lead leg out into space like Arroyo does — and yet, his reasons for doing it make some sort of sense, as well. And in between the two, there’s even something about the future of baseball in that kick. It’s a kick that contains multitudes.

First, let’s revel in its glory — in this case, from the hitter’s view. Is it… majestic?

Back in the spring, there was a gaggle of starting pitchers under consideration for the final spot in the Yankees rotation. Eventually, the lesser-known starter who wowed management got the chance. Jordan Montgomery has been a top-five rookie starter this year so far and, by all accounts, looks like a major leaguer. Now, the question has shifted. Now, we ask not “Will he pitch in the majors?” but “How good will he be?”

In your mind, you might have an idea of the relative strengths of the Indians’ Jose Ramirez. He’s what many might term a “good little player” — and that’s not a comment on his 5-foot-8 stature. It’s about the fact that he can run a little, hit for a little power, make a little contact, and play a few positions. Useful, but maybe not a star.

Then you might look at his stats from last year and find yourself surprised that he was nearly a five-win player. Then you might look at his stats from this year and find yourself surprised that he’s now a power-hitter. For the player himself, it required a little recalibration of his own approach. And that’s forced a recalibration on us — and on pitchers, as well.

Part of this job is writing about players who’ve put together interesting performances in small sample sizes. Really, at this point of the season, that describes basically every player. With Andrew Toles, though, it’s even harder: his whole career is a small sample size. And now, depending on the severity of his current knee injury, we might be forced to continue trying to evaluate him as a player based on very little evidence.

In that brief career, however, Toles has been good. Among active players who both (a) have recorded 200-plus plate appearances (Toles has 214) and (b) have yet to turn 25 (which he does in two weeks), Toles ranks 40th out of 99 by Wins Above Replacement — and he’s top 30 in isolated power.

That latter distinction is interesting. Projections, perhaps seeing powerless seasons in the minor leagues and dealing with a missed year in some form or another, don’t see that kind of power. I had to ask the player why they might be missing the point.
