While there has been much social media anticipation over the release of a years-old letter that Major League Baseball sent to the New York Yankees detailing illicit use of technology, sources told ESPN that the contents are relatively benign within the context of the sign-stealing scandals that occurred around the game at the same time.

Earlier this month, the U.S. Second Court of Appeals denied the Yankees’ request to keep the letter — from MLB commissioner Rob Manfred to Yankees general manager Brian Cashman — under seal. The letter was published by SNY on Tuesday.

That the Yankees fought to keep the letter under court-ordered seal in recent years raised eyebrows and fed conspiracy theories about what’s in the letter — to the degree that some baseball officials have been befuddled by the team’s handling of the issue, believing it would have been better to simply release the letter and move on.

According to sources, Manfred’s letter contains information about technology violations that occurred before the commissioner issued a memo to all teams in September 2017, a mandate that was regarded as a benchmark in the evolving concern about sign-stealing within the sport. Manfred warned teams that he would hold the front offices and staffers accountable for violations, and that violators faced penalties that included the possible loss of draft picks.

In January 2020, the Houston Astros and Boston Red Sox were penalized for using technology to steal signs late in the 2017 season and in 2018, after Manfred’s memo was issued.

In its investigation of the Astros, Major League Baseball determined that with the use of a television monitor, hitters were informed of the identity of the forthcoming pitch during their at-bats, in real time — extensive, systematic violations that would lead to the suspensions and dismissals of general manager Jeff Luhnow, manager A.J. Hinch and Astros bench coach/Red Sox manager Alex Cora, while former Astros player Carlos Beltran resigned from his new position as manager of the New York Mets.

The details contained within Manfred’s letter to the Yankees, sources told ESPN, note violations that players and staffers say became commonplace within the sport after instant replay monitors were installed within proximity of the dugouts in 2014.

Sources said Manfred informed the Yankees that MLB’s investigation found that Yankees players watched the monitors in 2015 and 2016 to discern pitch-sequence information that was then relayed to baserunners, in the hope that they could communicate this to the batter. Additionally, sources said the letter notes that former Yankees pitching coach Larry Rothschild called the replay room to ask about pitch identification, which is against the rules.

Manfred’s letter to Cashman, sources said, does not suggest any real-time conveyance of signs from the dugout to the hitters during their at-bats — the threshold established in the Astros’ case — or violations after Manfred’s memo in September 2017.
