SABR convention's "New Technologies in Baseball" panel is exciting glimpse into future of analysis

4 Comments

I’ll spare you most of the details of my trip to the Society for American Baseball Research (SABR) convention in Atlanta last week, but in terms of the actual baseball-related stuff the highlight for me was the “New Technologies in Baseball” panel.
Physics of baseball expert Alan Nathan was joined by Fan Graphs and Baseball Analysts writer Dave Allen, former The Hardball Times staffer and current Tampa Bay Rays baseball operations analyst Josh Kalk, Trackman business development director Rob Ristagno, and Sportvision video development director Rand Pendleton.
Allen took the stage sporting epic mutton-chops that, as Rob Neyer pointed out, made him look like Hyde from “That 70s Show.” Beyond that Kalk used props, including a baseball attached to a power drill that predictably malfunctioned and almost crippled Nathan. And last but not least, the technology shown, discussed, and hinted at was mind-boggling.
Over the past couple years MLB.com’s Pitch-f/x has changed the way many people analyze the game by providing previously unavailable details about pitching that turn “velocity” and “location” into a science. Field-f/x is now in the works, with the stated goal being to “create a digital record of all events” happening on each major-league field at all times. In other words, track everything. In truth a lot of the details went way over my head, but my mind was sufficiently blown.
Right now for each pitch thrown Pitch-f/x shows speed, location, release point, and movement. Field-f/x would take that and apply it to everything else, from batters and fielders to umpires and runners. What was the speed and trajectory of a fly ball? How was an outfielder’s jump on the fly ball? How precise was his route? How fast did he get there? What type of jump did the runner get? How quick he did move? Was an umpire in proper position to make a tough call?
And that vastly understates the potential impact because I don’t know or understand enough about the technology involved to do it justice and visual aids really made everything come to life, but I really think we’re on the verge of a huge shift in baseball analysis and the discussion panel has me very excited to see what’s next. If you think the depth of data available on sites like MLB.com and Fan Graphs right now are amazing, just wait until next season.
For more on what goes on at a SABR convention, read my recap.

Bronson Arroyo is throwing side-arm now

Nationals pitcher Bronson Arroyo has partial tears of tendons in his rotator cuff in his right shoulder. Considering he’s 39 years old, no one would fault him if he decided to call it quits. But he has one more idea, MASN’s Mark Zuckerman reports: Arroyo is going to throw side-arm, or at least three-quarters.

“It hurts when he gets on top [of the baseball],” manager Dusty Baker said. He continued, “So we’re taking our time. And if not, if nothing else, he’s a good guy to have in your organization.”

Arroyo missed the latter half of the 2014 season and the entire 2015 season after undergoing Tommy John surgery. Prior to that, he was known as a workhorse, racking up at least 199 innings in each of nine seasons between 2005-13.

Padres pitcher Robbie Erlin has a partial tear of his ulnar collateral ligament and he’ll need Tommy John surgery as a result, Dennis Lin of the San Diego Union-Times reports. Erlin landed on the disabled list on April 21. Now he’ll miss the rest of the season and likely the beginning of the 2017 season as well.

Erlin, 25, posted a 4.02 ERA with a 13/3 K/BB ratio in 15 2/3 innings spanning two starts and one relief appearance to begin the 2016 season.

Cesar Vargas moved into the rotation in Erlin’s absence and has pitched well thus far in two starts, yielding only one earned run with a 9/6 K/BB ratio over 10 1/3 innings.

The Reds’ bullpen set an ignominious record

Reds reliever Caleb Cotham allowed a pair of runs in the top of the eighth inning of Tuesday’s game against the Giants, setting a rather ignominious club record. It marks the 21st consecutive game in which the Reds’ bullpen has allowed a run, setting a new major league record, as C. Trent Rosecrans of the Cincinnati Enquirer points out.

Entering Tuesday’s action, the Reds’ bullpen had been by far the worst in the majors with a 6.54 ERA. The Padres’ bullpen, second-worst, is comparatively much better at 5.27.

The last time the Reds’ bullpen had a clean night was April 10 against the Pirates. That afternoon, Dan Straily, Jumbo Diaz, and Ross Ohlendorf combined for five scoreless innings in a 2-1 victory.

Aroldis Chapman will rejoin the Yankees on Monday

Yankees reliever Aroldis Chapman was suspended 30 games by Major League Baseball under its domestic violence policy for an offseason incident in which he allegedly pushed and choked his girlfriend, then discharged a firearm at least eight times in his garage. Monday marks game number 30, and Chapman is set to rejoin the club then, MLB.com’s Bryan Hoch reports. Manager Joe Girardi plans to insert Chapman directly into the closer’s role if a save situation arises against the Royals on Monday.

Chapman will make two appearances in the Gulf Coast League this week to continue warming up. He had been throwing in extended spring training games at the Yankees’ complex in Tampa.

The Yankees acquired Chapman from the Reds at the end of December, sending Caleb Cotham, Rookie Davis, Eric Jagielo, and Tony Renda to Cincinnati in return. While the back end of the bullpen hasn’t been an issue for the Yankees, seemingly everything else has for the 8-15, last place club.
