The Cardinals reportedly tried to steal Houston’s internal information, like scouting reports, on players, as well as discussions about player transactions, reports the New York Times.
Law enforcement officials who spoke with the Times did not say which team employees were the focus of the investigation or whether the team’s highest-ranking officials were aware of the hacking or had authorized it.
The FBI’s Houston field office is leading the investigation and has served the Cardinals and Major League Baseball with subpoenas seeking electronic correspondence.
If the accusations prove to be true, it would represent the first known case of corporate espionage in which a pro sports team has hacked into the network of another organization.
A spokesman for MLB Commissioner Rob Manfred said in a written statement that the league “has been aware of and has fully cooperated with the federal investigation into the illegal breach of the Astros’ baseball operations database.”
