The St. Louis Cardinals have the best record in the Majors. They also are in trouble with the FBI.

According to The New York Times, the Cardinals are under investigation by the FBI and the Justice Department for reportedly hacking into the internal networks of a rival team to steal closely guarded information about player personnel.

Investigators have uncovered evidence that someone in the Cardinals organization broke into the network of the Houston Astros that housed special databases they built. Discussions of trades, player development and scouting reports have all been compromised, according to law officials.

FBI officials have not confirmed which employee were the focus of this investigation or if the team's highest-ranking official knew about the alleged hacking. The FBI's field office in Houston is leading this investigation and already served subpoenas to the Cardinals for electric correspondence.

This marks the first-known case in which corporate espionage was involved between two professional sports teams. Usually, corporate espionage is between two companies and is a form of spying conducted for commercial purposes instead of purely national security.

Major League Baseball has also been served subpoenas. The organization released a statement regarding the alleged hacking

"MLB has been aware of and has fully cooperated with the federal investigation into the illegal breach of the Astros' baseball operations database," the statement read.

The Cardinals official under investigation has not been fired, suspended or put on leave. More than likely, the Cardinals will wait until after the investigation to discipline the official.

The Cardinals, who last won the World Series in 2011, have 11 titles overall, second only to the Yankees. From 1994 to 2012, both the Cardinals and Astros were division rivals and have met in the National League Championship Series in 2004 and 2005.

The Cardinals beat the Astros in the 2004 NLCS, and the Astros returned the favor by winning the NLCS in 2005.
