Last week, Travis Sawchik wrote an outstanding article titled “Can More MLB Hitters Get Off the Ground?” The article went in depth about the optimal swing plane, and about the resistance it can face within the game when a player’s thinking about trying to hit the ball in the air. Players have been instructed for decades to swing down on the ball in an attempt to generate backspin. Recent breakouts like Josh Donaldson and Justin Turner, however, can vouch for simply letting it fly. They’ve found their success from always swinging up.

For the most part, right now, the conversation is built upon anecdotes. There have been players who have changed their swings, but we haven’t seen anything reflected in the overall league numbers. Last year, the average ground-ball rate was 45%. Five years ago, the average ground-ball rate was 45%. That number seldom budges, and it does in part speak to baseball’s consistency. We aren’t seeing a reflection of a whole bunch of guys suddenly adopting uppercuts.

But then, it all depends on how you dig. It turns out there is something. A sign, if a small one, that we’ve entered a period of transition.

Pitchers and catchers have been in camp for all of a day and a half, and the baseball gods may have already claimed the first pitcher to feed their insatiable hunger for elbow ligaments and heartbreak. Alex Reyes of the Cardinals, a top-five prospect in all of baseball — if not the best (keep an eye out for Eric Longenhagen’s final rankings) — is headed for an MRI after experiencing the dreaded elbow discomfort. According to Jeff Passan, there’s significant worry within the organization that Reyes will need Tommy John surgery.

That’s a massive blow to the Cardinals, who were almost surely counting on Reyes for major contributions in their rotation. The rest of the pitching staff is largely a patchwork of the old (Adam Wainwright), the ineffective (Mike Leake) and the recently repaired (Lance Lynn). Only Carlos Martinez stands out as a real candidate to turn in 190 or so genuinely good innings. Knowing the Cardinals, they’ll probably still get a few prospects to emerge out of thin air and provide value at the big-league level, but Reyes is Reyes.

His fastball is the sort of pitch that’s spoken of in hushed and reverent tones. The curveball isn’t far behind. He’s the prototypical über-prospect in the age of Noah Syndergaard. He’s what they look like. For a Cards team that’s projected to win just 84 games, he was going to be a vital cog. He may be gone for the whole season.

There are two major implications here: one for the status of the club this year and one for the status of Reyes and his career. The second is largely an unknown. Every elbow reacts differently. Reyes may not need Tommy John. He may need it, and then another one. The Cards are almost surely praying that he’ll just need rest and rehabilitation, and that the ligament is still somewhat intact. Ervin Santana and Masahiro Tanaka have been pitching with partial tears of their ulnar collateral ligaments. It can be done, but it would likely eat into Reyes’ titanic velocity. We don’t yet know what the damage is.

If he does require surgery, the prognosis isn’t excellent. Research by Jon Roegele suggests that, for pitchers who undergo a Tommy John procedure between ages 16 and 23 (Reyes is 22), the median figure for innings pitched after the surgery is just 221. Only 40% of pitchers in that age group reach the 500-inning threshold. That 221-inning mark is worrisome for someone of Reyes’ age. But again, we’re not yet certain if he’ll need surgery.

Monday afternoon, I put up an InstaGraphs post titled “The Least Intimidating Hitter in Baseball.” The idea was to use a formula including fastball rate and zone rate, because, the way I figure, the more aggressively a hitter gets pitched, the less the pitchers are afraid of. I combined a couple z-scores to get a number I’ll refer to today as the Aggressiveness Index, and many of the players in the linked post are unsurprising. Turns out pitchers go after Ben Revere aggressively. Ditto Nori Aoki and Billy Burns. There’s nothing weird there.

But a certain name showed up in eighth place. Last year, pitchers didn’t show any significant fear of facing DJ LeMahieu. That makes sense if you weren’t paying attention, but LeMahieu played every day, and finished with a 128 wRC+. LeMahieu, ever so quietly, had himself a breakout, four-win season, yet it looks like pitchers just didn’t care.

Yesterday, the Royals reportedly agreed to a two year, $12 million contract with free agent left-hander Travis Wood, helping round out a pitching staff that needed some additional depth due to the tragic loss of Yordano Ventura. Wood had several other suitors, and in order to help convince him to come to Kansas City, it appears that the team has offered him a chance to compete for a spot in the starting rotation.

There’s nothing wrong with giving him a shot in spring training, especially since Nate Karns — the likely fifth starter before Wood signed — isn’t exactly a surefire starter himself. But while Wood is a useful pitcher who could likely be a significant asset for the Royals in a bullpen role, the Royals should probably hope that he bombs his rotation audition and accepts a role in relief instead.

We’ve been at it for some time now, utilizing granular exit-speed and launch-angle data to evaluate 2016 contact management (for ERA title-qualifying pitchers) and contact quality (for regular hitters) performances on a position-by-position, league-by-league basis. To wrap up this series of posts, we’ll next look at additional pitchers and hitters who didn’t meet the playing time thresholds to be covered previously.

When I was researching a piece about the Cubs’ clubhouse culture last month and the similarities it shared with the Clemson football program (i.e. it’s OK to have fun), I stumbled upon an interesting detail about the Cubs’ new clubhouse.

I knew the Cubs had the celebration room, regarded by some as a superfluous addition to the clubhouse. There’s also an impressive new strength-and-conditioning component. The old clubhouse, something of an subterranean alley way, was converted into a batting cage. There are a number of other amenities, as well, as one might expect of a new facility like this. The new clubhouse’s footprint of 30,000 square feet is about a quarter of the size of the Wrigley Field playing surface.

But it’s one of the smaller departments of the new clubhouse that I find interesting – the actual locker room space within the clubhouse. From an Associated Press story:

The Cubs decided to go with a circular shape — 60 feet, 6 inches in diameter, matching the distance on a baseball field between the mound and home plate — rather than the more conventional rectangle to encourage more unity and equality. There are no preferred corner lockers. Everyone can see one another.

Almost every other major-league home clubhouse I have entered is rectangular in shape. Certain locker spaces, like those with no neighboring locker on one side, are reserved for the most senior and/or most talented players. It’s not unlike the corner offices in your work place, which you might be hesitant to enter unannounced. There’s a sort of hierarchy of locker space, with certain players benefiting from a location next to unused locker space, which they use to store their spill-over belongings. The middle relievers, the bench players: they typically have no such luxuries.

While I’m not an expert in clubhouse design — nor the social manners and customs within those spaces — and while I’m only permitted clubhouse access along with other media for specific periods before and after games, I suspect the traditional clubhouse shape and layout does not always foster optimum discussion and collaboration opportunities.

And, to continue a theme from last week here at FanGraphs, one the great inefficiencies in today’s game is communication. Every club has the access to the same information, or similar information, but clubs ask different questions of the information and share information differently. I presume that there are different levels of collaboration in every organization.

It’s exciting to have so many statistics available to us when we’re trying to evaluate our favorite players. From the players’ perspective, though, it’s probably more exciting when those statistics allow them to improve themselves. From that point of view, metrics like launch angle and spin rate probably have a certain appeal that some others don’t: they provide a measurement of something that might help a player understand his game and get better.

There’s one problem, though — with spin rate, at least. Indications are that it’s difficult for a pitcher to change his in any material way. Still, as Jeremy Jeffress may have found, it can provide a window into betterment.

As spring-training camps open this week, as pitchers and catchers report to complexes across sunny Arizona and Florida, we are about to be inundated with stories suggesting a number of players are in the best shape of their careers. These are often players coming off down years, or veteran players who’ve dedicated the offseason to better diet and exercise with a view to lengthening their careers, or maturing players who’ve become more serious about their training and conditioning. Such claims are less often associated with 24-year-old pitchers who’ve just led the majors in WAR (6.5) and fastball velocity (98 mph) the previous season.

But Noah Syndergaard arrived bigger and stronger to Mets camp in Port St. Lucie, Florda, claiming to have added 15 pounds of muscle.

Syndergaard told the the New York Post and other outlets about one of his favorite dishes, which he used to add the lean mass and perhaps fight against deer overpopulation:

“My go-to is the Bowl of Doom,” Syndergaard said. “It’s sweet potato and hash with bacon, and you have buffalo in it and venison sausage, avocado and scrambled eggs, and that is plenty. That’s primarily what my diet consisted of this offseason.”

Resident pitching guru Eno Sarris already wrote this afternoon that the weight gain and other potential improvements could mean even better things for Syndergaard.

Maybe because it’s an example of the Best Shape of His Life story taken to its inevitable conclusion or maybe because it’s the only news that’s occurred other than pitchers and catchers saying “here” in a spring-training facility somewhere. In either case, it seems relevant to discuss how Noah Syndergaard showed up to camp with a reported extra 17 pounds of muscle.

To understand the implications of that weight gain, we’d ideally examine big weight gainers of the past and use that data to discuss the situation. Unfortunately, that’s not really an option: listed weights are notoriously incorrect and also don’t change on a yearly basis.

What we can do is look at the best available research on strength training and pitching. We can also look at the pitcher himself and put this newest change in the context of the individual. Once you do, it doesn’t seem so drastic. Then the weight change is just another in a line of ambitious adjustments Syndergaard has already tackled.
