Over the winter, the Dodgers re-signed Rich Hill. They did so because they knew that, when he was able to pitch, Hill looked like one of the best starting pitchers in the game. And then 2017 went and got underway. Through the earlier part of 2017, Hill looked like one of the more frustrating starting pitchers in the game. The stuff, for the most part, remained there, but Hill didn’t have his same control, and his remarkable curveball was no longer working. I wrote about Hill in the middle of June, at which point his curveball had the lowest run value among all curveballs, out of everyone. It made me wonder where, exactly, Rich Hill was. Could someone who reappeared so suddenly disappear with similar speed?

Since I wrote about Hill and his struggles, he’s gone back to looking like one of the best starting pitchers in the game. In three starts, he’s allowed four runs over 19 innings, with six walks and 26 strikeouts. The easy explanation is that Hill has simply regressed to the mean. That is, his newer mean, the one he began establishing a couple years ago. That explanation would ignore the changes that Hill has folded in. Regression to the mean isn’t an automatic process. Rich Hill has simultaneously simplified and grown more complex.

We might as well start this off with a Buster Olney tweet:

Teams asking about Justin Verlander; perception is DET looking for big,big,big return w/out salary offset. Owed $70m for rest of ’17,’18.’19

— Buster Olney (@Buster_ESPN) July 4, 2017

Just from reading that tweet alone, one could infer a few things. One, that the year hasn’t gone very well for the Tigers. That much is true, and the Tigers are only in the playoff race in the way that everyone in the American League is still in the playoff race. The Tigers are closer to the AL basement than they are to a playoff spot. Two, that Justin Verlander is available, and he’s been good enough to be interesting. That much is also true. And three, that a Verlander trade is going to be very challenging to execute. That much is certainly true. Verlander’s is the most fascinating name on the trade market, but as things stand, I don’t know how two sides could come together.

For many people, a good fireworks show is a welcome part of their extended 4th of July weekend. I mean, who doesn’t like one, except for some really good dogs out there? That said, if you attended a fireworks show every night of the entire summer, it’d probably get old pretty quick, right? Right.

Well, what I’d like to do here is consider a different sort of fireworks — one more relevant to our national pastime — and the possibility of them wearing out their welcome.

For the sake of the analogy, home runs will take the place of fireworks. Homers are occurring more than ever and, I submit, it’s going to get old pretty soon. Oh, we’ve been down this road before, in the so-called steroid era, which peaked right around the turn of the 21st century. Homers got pretty old then, too.

Well, we’re hitting way more homers now than we were hitting then. In the year 2000, major-league hitters combined for 1.17 homers per team per game, an all-time high. Or, I should say, an all-time high until now. Now we’re rolling along at 1.26 homers for the season, shattering the previous high.

As for the implications of the home-run spike, I’ll discuss that in a moment. First, a couple key notes for context. In 2000, teams struck out an average of 6.45 times per game. That average has been on a rocket ship upward over the last decade, up to 8.24 thus far this season. As for walks, they had been trending downward for a while, from 3.42 per team per game in 2009, down to 2.88 in 2014. Well, that has turned upward in a big way, up to 3.27 thus far in 2017. What we have here is the Russell Branyan-ization of baseball: the Era of the Three True Outcomes is upon us.

According to this weekend’s ESPN Sunday Night Telecast, Bryce Harper has, in recent years, often performed his pregame routine and taken batting practice indoors, in the bowels of major-league ballparks, much to the disappointment of ballhawks across America. But Harper revealed himself over the weekend in St. Louis, taking BP on the field, and any time a star like Harper deviates from a routine, it raises curiosity. During the broadcast, ESPN’s Jessica Mendoza related how she’d asked Harper about the change. He said he wanted to hit some batting practice home runs, wanted to see the ball travel.

Perhaps he wanted to see how an adjustment, something akin to an R&D prototype, would work outside a lab setting, outside of an indoor batting cage.

When I think about Harper’s swing, I think about the violence of it. The leg kick, the force compelling his back foot — his left foot — to rise from the ground. Former Nationals beat writer Adam Kilgore wrote an excellent multimedia piece about Harper’s swing for The Washington Post several years ago.

From that piece:

[Nationals video coordinator Rick] Schu scanned through video and found film of Harper hitting. He arranged clips of Harper and Ruth side-by-side on the monitor and stopped at the moment each hitter’s bat connected with a pitch. In each still picture, he saw a stiff front leg, an uncoiling torso and a back foot lifting off the ground. “Wow,” he thought. “That’s identical.” …

“The full thing is God-given,” Harper said. “I don’t know how I got my swing or what I did. I know I worked every single day. I know I did as much as I could with my dad. But I never really looked at anything mechanical. There was nothing really like, ‘Oh, put your hands here.’ It was, ‘Where are you comfortable? You’re comfortable here, hit from there.’ ”

What’s interesting, at least to this author, is that Harper is willing to tinker with a gift that allowed him to reach the majors at 19. What’s perhaps troubling for the opposition is that he continues to look for ways to improve despite already possessing an NL MVP on his resume and returning close to that form thus far in 2017. He’s still just 24 — he won’t turn 25 until October — and is four months younger than Aaron Judge. His youth suggests he’s still learning himself and the game. And on the ESPN telecast, Harper debuted an apparent decision to trade power for control — or at least explore it. It’s not a swing I recall him taking — at least not regularly — a swing seemingly executed at 80% effort.

Against the hard-throwing Carlos Martinez, Harper shelved his signature leg kick. To commence his swing, he slightly raised his right foot but not completely from the ground, and took a much less explosive movement. He seemed to consciously trade power for control.

Consider Harper’s first swing of the evening:

This is Matt Swartz’ first piece as part of his July residency at FanGraphs. A former contributor to FanGraphs and the Hardball Times — and current contributor to MLB Trade Rumors — Swartz also works as consultant to a Major League team. You can find him on Twitter here. Read the work of all our residents here.

I’m excited to begin my FanGraphs Residency this month, during which I’ll present an updated analysis of the Dollars per WAR estimates that I’ve used for a long time. I’ve written about the Dollars per WAR framework for analyzing the free-agent market for nearly a decade now, most recently in a three–part series at Hardball Times using data through the 2013 season. In that collection of posts, I established the important definition of Dollars per WAR that I will use throughout this series of articles — namely, the average cost of acquiring one win above replacement on the free-agent market.

Since I’ve written about this, however, there has been a progressively minded, labor-sympathetic pushback against this framework that I felt it was important to address, because if the criticism were fair it would cast a long shadow across all of the analysis in the coming articles. Fortunately, I believe that this criticism is misguided, even if you accept the value system that proponents of this line of criticism generally espouse.

From my perspective, I will remain agnostic on the value system itself in these criticisms, but simply explain why I think this type of analysis does not line up with an anti-labor view at all. I will admit up front that I consult to a Major League team and therefore, when working for them, I do represent the interests of that employer. What I say in these articles, however, will represent only my own views — and, in general, I’m writing this from my perspective as a frequent contributor on this topic predating this good fortune, and as an economist — but neither as a team employee representing ownership nor as a former Department of Labor employee, either.

I’d like to address two well-written and well-argued articles here that I believe characterize some of the labor-related concerns. One by Mike Bates asks if statheads are pro-ownership and another by Michael Baumann reframes a series of team-friendly contracts as inherently bad and unfair. What I’d like to consider here is the implicit suggestion made by both authors that, when teams individually target lower cost-per-WAR players, that this doesn’t affect the prices of these lower cost-per-WAR players and drive them up, but rather that it serves only to drive down the price of higher cost-per-WAR players. This seems very unlikely to be true according to some of the increased prices for lower cost-per-WAR categories of players I find in later pieces in this series.

After their roster was ravaged by injuries, the Yankees promoted a trio of promising hitting prospects last week in Tyler Wade, Miguel Andujar and Dustin Fowler. Fowler, the most promising of the three, was supposed play regularly in New York’s outfield. Unfortunately, his big-league career was derailed as soon as it started in horrific fashion.

At a table in the center of the visiting clubhouse last week, in the depths of Cleveland’s Progressive Field, Jonathan Lucroy was seated holding his catcher’s glove in his left hand and a flat-head screwdriver in his right. He used the tool to loosen and tighten different laces in the glove. He spent perhaps 20 minutes on glove maintenance that day — a day on which, incidentally, he wouldn’t appear in the starting lineup.

There’s been some focus on Lucroy’s glove recently. Lucroy’s glove, his receiving skills, were once the game’s best. What’s happened to Lucroy’s framing in recent years, however, is something of a mystery.

There have been some stunning declines in baseball over the last few seasons. There was Andrew McCutchen’s age-29 drop-off, unprecedented in its depth for a star-level player, and his cold start to the current season. There’s Jake Arrieta’s decline from Cy Young winner in 2015 to middling starting pitcher since the second half of last season.

Perhaps less apparent, less publicized as these — but still as significant — is what has happened to Lucroy’s framing numbers.

We are very nearly ready for this season’s All-Star Game. Now that the rosters have been announced, it’s mostly academic. We’ll have the annual injury replacements and then the pitcher replacements and, of course, the Final Vote. By the time they line up along the bases for intros next Tuesday, many of the players who were originally denied a roster spot will have found a place by other means. That’s the nature of this process. Let’s take a look at what this year’s game is likely to offer.

It strikes me this year, as I scroll through the leaderboards, how few deserving players have been omitted from the initial rosters. In the National League, there are a couple of big snubs in Justin Turner, Anthony Rendon and Alex Wood, but Turner and Rendon are candidates for the Final Vote, and Wood is a good bet to make the roster, especially if Clayton Kershaw starts on Sunday and thus becomes ineligible to pitch in the ASG.
