The Houston Astros won the World Series in 2017 after scoring the most runs in baseball in the regular season. They also had the most total bases and the highest team batting average.

And according to a report by The Athletic on Tuesday, they often knew what pitches were coming because of a scheme using a camera and a trash can.

The report said the Astros, in violation of major league rules, had used a camera in center field to capture signs from opposing catchers to the pitchers at Minute Maid Park in Houston, transmitted images to a monitor near the dugout and then relayed information to the batter by banging on a trash can .

Mike Fiers, a former Astros pitcher who is now with the Oakland Athletics, joined some anonymous sources in confirming the caper, and the Astros said Major League Baseball was looking into the matter.
