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:

Devised originally in response to a challenge issued by sabermetric forefather Rob Neyer, and expanded at the request of nobody, NERD scores represent an attempt to summarize in one number (and on a scale of 0-10) the likely aesthetic appeal or watchability, for the learned fan, of a player or team or game.

How are they calculated? Haphazardly, is how. An explanation of the components and formulae which produce these NERD scores is available here. All objections to the numbers here are probably justified, on account of how this entire endeavor is absurd.

Godley (64.0 IP, 80 xFIP-) vs. Wood (73.2 IP, 60 xFIP-)
One might not feel comfortable regarding either Zack Godley or Alex Wood as above-average — or even elite — major-league pitchers. One, employing reason, likely feels uncomfortable about a number of other things in the world, as well, though. Perhaps tonight’s game is best regarded, then, as a training ground for discomfort.

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.

Corbin (90.2 IP, 94 xFIP-) vs. Kershaw (116.1 IP, 66 xFIP-)
The Dodgers currently possess the second-best offense in the majors and also the fourth-best defense in the majors. Or, at the very least, they’ve recorded the second-best offensive and fourth-best defensive marks so far. In either case, it’s not surprising they currently occupy first place in the NL West. What might be surprising is that the D-backs are situated just 2.5 games behind them in that division despite having recorded less strong offensive and defensive marks. Probability suggests that they’ll finish the evening either 1.5 or 3.5 games behind.

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.
