baseball, sign stealing is the act of observing the
signs
Signs may refer to:
* ''Signs'' (2002 film), a 2002 film by M. Night Shyamalan

being signaled by the opposing
catcher to the
pitcher or a coach, and the subsequent relaying of those signals to members of one's own team. Sign stealing is done with the intent of gaining advance knowledge of the upcoming pitch and communicating it to the batter, thereby giving them an advantage.
Legal sign stealing typically involves the signs being observed by a runner on second base and then relayed to the batter through some sort of gesture. Illegal sign stealing involves mechanical or electronic technology; the rules regarding this have become more stringent over time and continue to evolve.
Sign stealing has been in practice almost since the
game's origin in the 19th century, and has continued to be used in recent times.
Legality
According to the
unwritten rules of baseball, stealing the signs that are given by the third base coach, or those of the catcher by a
baserunner
In baseball, base running is the act of running from base to base, performed by members of the team at bat.
Base running is a tactical part of the game with the goal of eventually reaching home base (home plate) to score a run. Batters strive to ...
on
second base, is acceptable, and it is up to the team giving the signs to protect them so they are not stolen. Even so, pitchers may retaliate when they believe their signs are being stolen with a
brushback pitch. On the other hand, a batter peeking in to see the catcher's signs is definitely not tolerated. The signs the catcher sends to the pitcher to call for the next pitch are considered more "sacred" than the signs a third base coach relays to the batter.
Stealing signs is not necessarily a violation of
Major League Baseball's (MLB) rulebook; it depends how the signs are stolen. At the December 1961
Winter Meetings, the
National League banned the use of a "mechanical device" to steal signs. The use of electronic equipment is not specifically forbidden by MLB rules, but in 2001,
Sandy Alderson, while serving as executive vice president for baseball operations of MLB, issued a memorandum stating that teams cannot use electronic equipment to communicate with each other during games, especially for the purpose of stealing signs.

Notable incidents
19th century
The oldest recorded instance of a team attempting to steal signs dates back to 1876, when the
Hartford Dark Blues hid a person in a shack to tip off their hitters when the pitcher would throw a
curveball
In baseball and softball, the curveball is a type of pitch thrown with a characteristic grip and hand movement that imparts forward spin to the ball, causing it to dive as it approaches the plate. Varieties of curveball include the 12–6 curve ...

21st century
Technology has been a component in most recent sign stealing incidents.
2017 Houston Astros scandal
After the 2019 season, Mike Fiers alleged that the 2017 Houston Astros used technology to illegally steal their opponents' signs and relay them to their hitters. MLB and the Astros opened an investigation into the allegation, and it was expanded to encompass the 2018 and 2019 seasons. On January 13, 2020, Rob Manfred announced that MLB's investigation confirmed that the Astros illegally used a video camera system to steal signs during their 2017 and 2018 seasons. The organization was penalized with a $5 million fine, forfeiture of first- and second-round draft picks in 2020 and 2021, and the suspension of general manager Jeff Luhnow and field manager

A. J. Hinch for one year; Luhnow and Hinch were subsequently fired by the team the same day. Three days after the Astros penalties were announced, the New York Mets and Carlos Beltrán (an Astros player at the time of the scandal) mutually parted ways. Beltrán had been hired as the team's new manager on November 1, 2019, so at the time of the announcement he had never managed a game for the team. Beltrán was the only player specifically named in MLB's report on the Astros scandal. While he was not directly linked to any prohibited activity, he was one of several Astros players who met during that season to discuss improvements in their sign stealing.
2017 Boston Red Sox: Apple Watch
During the 2017 season, the Boston Red Sox were fined by MLB for using an Apple Watch to relay stolen signs to hitters in games against the New York Yankees. On September 15, 2017, commissioner Rob Manfred had said in regards to the investigation into Boston's illicit use of an Apple Watch: "I have received absolute assurances from the Red Sox that there will be no future violations of this type."
On February 4, 2020, MLB Network journalist Peter Gammons reported that former Red Sox player Chris Young told him that he was the mastermind of the Red Sox' Apple Watch scheme, telling him "I started the whole Apple Watch thing. I got it from when I was with the Yankees." Young later denied this, and Gammons retracted his comments via Twitter. SportsNet New York (SNY) revealed that Young had been interviewed by MLB officials as part of the 2017 investigation against the Red Sox and that multiple sources told the sports news agency that Young was in fact a leader of the team's 2017 Apple Watch scheme.
The same year, a phone conversation between Yankees pitching coach Larry Rothschild and replay room officials revealed that the Yankees engaged in sign stealing with an Apple Watch as well, which resulted in the Yankees being fined. A 2017 letter from commissioner Manfred to Yankees general manager Brian Cashman, made public in 2022, indicated the Yankees were fined $100,000 for their sign-stealing practices.
2018 Boston Red Sox: video replay
On January 7, 2020, the Red Sox were implicated in another sign stealing scandal after three unnamed team members told '' The Athletic'' that the Red Sox had used their replay room to steal signs of opposing teams during the 2018 season. On January 13, 2020, Manfred stated that he would determine the appropriate punishment for Red Sox manager Alex Cora, who was also implicated in the Astros scandal, when the investigation was completed. The next day, Cora and the Red Sox mutually agreed to part ways; Dave Dombrowski, the general manager who hired Cora, was dismissed from the Red Sox before the 2018 sign stealing scandal was made public.
On April 22, 2020, commissioner Manfred issued his report from the investigation, determining that the Red Sox replay operator had "utilized the game feeds in the replay room" to decode sign sequences but those actions were "limited in scope and impact", as the decoding only happened during some occurrences of the opposing team having a runner on second base and were not known to "then-Manager Alex Cora, the Red Sox coaching staff, the Red Sox front office, or most of the players".[ The video replay operator was suspended for the 2020 season and the team forfeited their second-round selection in the ]2020 MLB draft
