M.L.B. Will Analyze Spin Rate to Detect Ball Doctoring – The New York Times

In a continuing effort to combat the use of foreign substances to increase ball movement, baseball will incorporate Statcast data.

Doctoring baseballs with foreign substances to increase spin and movement has been around for as long as baseball has been played. To try to combat the practice, Major League Baseball is going high tech for the 2021 season, adding spin rate analysis to its arsenal of methods for detecting changes and enforcing existing policies.
In a memo distributed to teams on Tuesday, Michael Hill, a senior vice president for baseball operations, detailed the enhanced monitoring process. There will be increased scrutiny of club spaces, inspection and documentation of balls taken out of play and, in the biggest change from previous methods, the league will use Statcast data to compare spin rates for players who are suspected of doctoring balls, checking to see if the numbers for the game in question differ significantly from their career norms.
Umpire enforcement on the field will stay consistent with past practices, according to Hill’s memo. “The foregoing enhanced monitoring measures, however, will provide the commissioner’s office with a separate evidentiary basis to support a finding that a player has violated the foreign substance rules,” he said.
The spitball and other so-called freak deliveries were banned from the sport in 1920, with pitchers initially given one year to adjust to the change before the rule was adjusted to allow “registered” spitball pitchers to finish their careers without changing. But foreign substances like spit, petroleum jelly, pine tar, rosin and sunscreen lotion continued to be used regardless of rules, and enforcement has been spotty at best.
In perhaps the most extreme example of baseball’s indulgence of the act, Gaylord Perry, a star right-hander, was so synonymous with the doctoring of balls that his 1974 autobiography was called “Me and the Spitter.” The confession did not derail him, as he continued to pitch until 1983, won 314 games and was elected to the Baseball Hall of Fame in 1991.
M.L.B. has recognized the need to improve the grip on baseballs in recent years, and has studied how a stickier ball would perform. With the adjusted policy in place, the league hopes to have better data, while also letting players know that it is monitoring the situation.
David Ross, the manager of the Chicago Cubs and a former catcher, said that pitchers getting a proper grip on the ball is a legitimate safety issue, even if substances have been abused by some players in hopes of gaining an unfair advantage.
“Around the league, as long as I’ve been in here, there’s some kind of just wanting to be able to hold onto the ball and guys putting a little bit on that,” he said in a video conference with reporters. “The stuff that you’re hearing that’s out there is doctoring the baseball, and I think M.L.B. is on the right track to try to crack down on that.”
Everywhere I go in baseball, people want to talk about the ball. Lazy flies turn into homers. Pitchers’ best pitches don’t mambo like they used to.
Thursday is Opening Day, and M.L.B. is taking action. Meet the new ball →
First, some history. M.L.B. began cracking down on steroids in 2003. Even so, since the start of 2016, hitters have been mashing home runs in record numbers. The high mark for a season: 6,776 in 2019. Exciting, right?
Not for pitchers. Justin Verlander, a two-time Cy Young Award winner, groaned that the league was spring-loading the ball. M.L.B. denied it, saying there would always be inconsistency because balls were made largely by hand.
Scientists hired by M.L.B. cited two main culprits for the increase in homers: More players were swinging for the fences, and slightly lower seams and other factors were making the ball fly farther. Also, the average ball was a tiny bit bouncier than it had been.
To make the ball less bouncy, the manufacturer, Rawlings, loosened the tension on the first of three wool windings within it. The result, M.L.B. said: a ball that weighed 2.8 grams less and traveled, on average, a couple of feet fewer on a 375-foot fly ball.
Home runs are up slightly this spring, but Gerrit Cole, the Yankees’ ace, said that the balls felt more consistent, and San Diego Padres pitcher Blake Snell noticed thicker laces and less carry. “Definitely a different ball,” he said.
I’ll be counting home runs — and player complaints — all season. Here’s more on the controversy:
Correction: An earlier version incorrectly said home runs were slightly down this spring. They were slightly up.
The doctoring of baseballs came to the forefront this off-season when a former visiting clubhouse manager for the Los Angeles Angels who had been fired by the team filed a lawsuit in which he claimed to have helped Gerrit Cole of the Yankees, Justin Verlander of the Houston Astros and several other pitchers obtain ball-gripping substances. The suit, in which the clubhouse manager claimed to have text messages from Cole asking for a substance to use on baseballs, was eventually dismissed by a federal judge.
“It’s an ongoing legal issue, and I am not comfortable talking about it now,” Cole told reporters shortly before the case was dismissed.
The memo from M.L.B., which came after teams for years had been expected to police the situation themselves, gives specific guidance on club employees’ responsibilities in regard to ball-doctoring substances. It says fines and suspensions could apply to activities including, but not limited to, handling foreign substances, advising a pitcher how to use or otherwise mask the use of foreign substances, interfering with the collection of game-used baseballs and failing to report observed violations of these rules by players or staff.
It also said that club leadership could be held accountable for the actions of staff members.
“I think M.L.B.’s on top of it and that’s the best we can ask for, right?” Ross said. “Try to crack down and let’s get this thing back to everybody on a level playing field.”
