Boston Red Sox

Major League Baseball says an investigation into the Houston Astros has yielded no proof that the defending World Series champions were trying to illegally steal signs from the Red Sox during Game 1 of the American League Championship Series on Saturday.

In a statement, the league says the Astros employee removed from a credentialed area near the Red Sox dugout was “monitoring the field to ensure that the opposing Club was not violating any rules.”

The man, who was identified as Kyle McLaughlin by Jeff Passan of Yahoo Sports, was also removed from an area near the Indians dugout during the ALDS after security spotted him taking photos of the Cleveland dugout.

“All Clubs remaining in the playoffs have been notified to refrain from these types of efforts,” the statement went on to say. “We consider the matter closed.”

Major League Baseball said the Commissioner’s Office received calls from multiple teams ahead of the playoffs regarding sign-stealing and improper use of video equipment. The league says multiple clubs were the subject of those concerns, not just one team.
