The Houston Astros could be in even more hot water fresh off a surprising World Series loss to the Washington Nationals.

According to this report from Ken Rosenthal and Evan Drellich of The Athletic, Major League Baseball is investigating who had knowledge of the Astros stealing signs during the 2017 season.

“NOW, AN MLB INVESTIGATION INTO THE ASTROS’ CULTURE IN THE WAKE OF THE TEAM’S FIRING OF ASSISTANT GENERAL MANAGER BRANDON TAUBMAN COULD BE EXPANDED TO DETERMINE WHO IN THE ORGANIZATION WAS AWARE OF THE SIGN-STEALING PRACTICE — AND WHETHER IT CONTINUED OR EVOLVED IN SUBSEQUENT SEASONS,” THE REPORT READ.

The Athletic confirmed in this report that the Astros did indeed steal signs during home games, using a camera in the outfield to do so.

Former members of the team confirmed this.
