No sooner had the Yankees opened their summer camp — or spring training 2.0, or whatever we’re calling this tense and perhaps tenuous ramp-up to the long-delayed 2020 season — on Saturday than they got their first scare: the sight of pitcher Masahiro Tanaka being drilled in the head by a line drive hot off the bat of Giancarlo Stanton. The 31-year-old righty never lost consciousness but was taken to the hospital for testing and further evaluation, and while he was released, on Sunday he was diagnosed with a concussion. The terrifying sequence was a reminder that the coronavirus isn’t the only thing for players to fear during this abbreviated build-up to the regular season, but all things considered, both he and the Yankees look quite lucky right now.

At Yankee Stadium, in a simulated game that marked their first formal workout of the restart, Tanaka had faced Aaron Judge and Gleyber Torres before Stanton stepped in. The slugger smoked a line-drive comebacker that struck the pitcher on the right side of the head and ricocheted high in the air (I’ll leave it to you to find the video). Keep in mind that since the advent of Statcast in 2015, only Judge and Nelson Cruz have higher average exit velocities than Stanton’s 93.4 mph — he is emphatically not the guy you want pounding a ball off your noggin. According to James Paxton, the ball came off the bat at a sizzling 112 mph. Tanaka fell to the ground, writhing in pain, and stayed down for about five minutes before sitting up and eventually being helped off the field with the assistance of two trainers.

Back in early 2013, I wrote a guest article for Baseball Prospectus entitled “How Far Did That Fly Ball Travel?” In that article, I posed a seemingly simple question: Can we predict the landing point of a fly ball just after it leaves the bat? A more precise way to ask the question is as follows: Suppose the velocity vector of a fly ball just after leaving the bat is known, so that the exit velocity, launch angle, and spray angle are all known. How well does that information determine the landing point? I then proceeded to investigate the question, at least for home runs, with the aid of HITf/x data for the initial velocity vector and the ESPN Home Run Tracker for the landing point and hang time. Using a technique described in the article, that information was used along with a trajectory model to reconstruct the full trajectory and extrapolate it to ground level to determine the fly ball distance. The answer to the question was immediately obvious: The initial velocity vector poorly determines the fly ball distance.

This conclusion led naturally to the next question: Why? One obvious reason is variation in atmospheric conditions, especially wind. However, the data revealed that the variation in home run distance for given initial velocity was as large in Tropicana Field, where the atmospheric conditions are expected to be constant, as in the rest of the league. So that was eliminated, at least as the primary culprit.

The article then went on to consider variation in two other parameters that play a role in fly ball distance: backspin ω_b and drag coefficient C_D. Neither of these parameters were directly measured. Rather they were inferred, along with the sidespin ω_s, in the procedure used to recreate the full trajectory. The analysis showed the following:

• For a given value of C_D, distance increases as ω_b increases. This makes sense, since larger backspin results in greater lift, keeping the ball in the air longer so that it travels farther.
• For a given value of ω_b, distance decreases as C_D increases. Again this makes sense, since greater drag is expected to reduce the carry of a fly ball. Interestingly, this was the first appearance in print of a suggestion of a significant ball-to-ball variation in the drag properties of baseballs.
• There was a moderately strong positive correlation between C_D and ω_b, suggesting that the drag on a baseball increases with increasing spin, all other things equal. Although this effect is well known for golf balls and had been speculated for baseballs in R. K. Adair’s excellent The Physics of Baseball, to my knowledge this is the first real evidence showing the effect for baseballs.
• Given that both lift and drag increase with increasing ω_b and that they have the opposite effect on distance, it was tentatively concluded that at high enough spin rate there would be no further increase (and perhaps even a decrease) in distance with a further increase in spin.

The Cincinnati Reds have been eagerly awaiting Hunter Greene’s return from Tommy John surgery. And for good reason. Prior to going under the knife 15 months ago he was hitting triple digits with his heater. Drafted second overall by the Reds in 2017 out of a Sherman Oaks, California high school, Greene is No. 77 on our 2020 Top 100 Prospects list.

According to Kyle Boddy, his return is nigh. Cincinnati’s pitching coordinator recently spent time with Greene in California, and he deemed the 20-year-old’s rehab “basically done.” Throwing in front of a Rapsoto, Greene was “an easy 97-plus [mph], reaching 100-101 when he was rearing back.”

More than a return to health is buoying the return to form. With the help of technology — “he’s really getting into the metrics and analytics” — and a former Chicago White Sox pitcher, Greene has made a meaningful change to his delivery. What had been “long arm action with a big wrap in the back” is now a shorter-and-cleaner stroke.

“That’s a credit to people like James Baldwin, who was the rehab coach and is now our Triple-A coach,” Boddy told me. “JB has worked with Hunter extensively, leaning on materials from Driveline Plus. Hunter has had a tendency to cut his fastball, so we’ve relied on a lot of video to show him how to fix that and get more carry.” Read the rest of this entry »

Ryan O’Rourke experienced life in the big leagues. The recently-retired left-hander appeared in 54 games with the Minnesota Twins between the 2015 -2016 seasons, and in two with the New York Mets last year. But the bulk of his career was spent in the minors. A 13th-round pick by the Twins in 2010 out of Merrimack College, O’Rourke toiled down on the farm in each of his 10 professional campaigns.

He experienced a lot. The minor leagues are an adventure, and while often fun, they are by no means a bed of roses. The pay is bad, the travel and accommodations are arduous, and for the vast majority of players, crushed dreams are inevitable. Moreover, success and failure aren’t always dictated by talent alone.

———

David Laurila: How would you describe professional baseball at the minor-league level?

Ryan O’Rourke: “Now that I can look at it from a helicopter point of view, I’d say that it’s a crapshoot in the truest sense of that word. If you don’t end up with the right organization, and your development isn’t a priority, your path to the big leagues is so much more difficult than it already is.

“I was fortunate to be with the Twins, who were very good about taking care of people, but I’ve heard horror stories from other teams. If you’re a nobody — anyone outside the 10th round is probably a nobody — and don’t show promise right away… let’s just say that guys who get big money in rounds one through 10 are given countless opportunities over someone who may have deserved it more.

“That’s the sad nature of the minor leagues, which, from a business standpoint, I do understand. If you gave one guy $400,000 and another guy $4,000, it’s obvious who you’re keeping. And sometimes it’s a matter of a coach liking you or not. Sometimes you’re cut because you didn’t impress one guy.”

Laurila: How much jealousy and resentment is there of high-round guys? For instance, Byron Buxton is a talented player but he also got a $6 million signing bonus. Read the rest of this entry »

There are plenty of rule changes coming to baseball in the 2020 season. We’ve written about many of them: the universal DH, the extra-innings rule, and expanded rosters, to name a few. Today, I thought I’d take a crack at something less immediately evident but still meaningful: the denser schedule.

In 2019, teams played 162 games in 186 days. That meant the schedule was 13% off days, give or take. Four of them were clustered around the All-Star break, but for the most part, they were spread out evenly. Off days are a welcome respite in a team’s schedule, a break from the grind. Sometimes they’re necessary for travel, of course, but mostly they’re meant just to be time for players to recover from the grueling march to October. This year, 60 games in 66 days means only 9% off days.

For most players, an off day is simply that. For pitchers, however, days of rest carry greater meaning. A day off is a day closer to starting again. Imagine a schedule with 80% off days — a game every five days. Your ace could pitch more or less every game, give or take a maintenance break here and there. Conversely, in a schedule with no off days at all, every pitcher would take the same number of turns in the rotation.

Given an off day, teams can, in theory, squeeze extra starts out of their ace. In practice, it doesn’t quite work that way. It also doesn’t not work that way, however; seven pitchers made 34 starts in 2019, more than a fifth of the games on the schedule. Teams are logical about giving their best starters extra turns when they can. An extra Justin Verlander start beats a Jose Urquidy start, no offense to Urquidy. Read the rest of this entry »

Below is another installment of my series discussing each team’s 60-man player pool with a focus on prospects. If you missed the first piece, you’re going to want to take a peek at its four-paragraph intro for some background, then hop back here once you’ve been briefed. Let’s talk about the National League East.

Atlanta Braves

Prospect List / Depth Chart

The Braves have pooled the most catchers in baseball with seven (eight if you count Peter O’Brien and the faint memory of his knee-savers), several of whom are prospects. I think Travis d’Arnaud’s injury history and the implementation of the universal DH makes it more likely that Alex Jackson opens the season on the active roster. I don’t think this would save Atlanta an option year on Jackson since they optioned him in mid-March, and Atlanta’s bench projects to be very right-handed, so he might be competing with Yonder Alonso for a spot.

We’re probably an Ender Inciarte injury away from seeing Cristian Pache play in the big leagues every day. Aside from him, I doubt we see any of the recently-drafted position players (Drew Waters, Braden Shewmake, Shea Langeliers) playing in the bigs this year, and if William Contreras debuts it’s likely because a couple guys ahead of him have gotten hurt.

Ben Lindbergh and Meg Rowley banter about Ben’s effusive streaming recommendation, the Korean baseball drama Stove League. Then (8:51) they start the second episode of their week-long celebration of the Negro Leagues by bringing on Jeremy Beer, author of the award-winning baseball biography Oscar Charleston: The Life and Legend of Baseball’s Greatest Forgotten Player, to talk about Charleston’s bona fides as one of the top 10 baseball players of all time, why his fame falls short of his accomplishments, and the challenges of researching Negro Leagues stars. Lastly (46:18), they speak to Invisible Ball of Dreams author and Ball State University professor Emily Ruth Rutter about two of the only non-documentary movies to focus on the Negro Leagues, The Bingo Long Traveling All-Stars & Motor Kings (1976) and Soul of the Game (1996), touching on where they succeed and fail, the differences in their portrayals of the Negro Leagues and Negro Leaguers, and the history of cinematic and literary representations of Black baseball.
