Major League Baseball says it will take no action over allegations the Houston Astros had cheated during the playoffs.

On Tuesday, a source told the Associated Press that the Cleveland Indians had filed a complaint with MLB about a man associated with the Houston Astros attempting to film in their dugout during Game 3 of the AL Division Series. MLB also said it was aware of a report by Metro Boston that a man claiming to be an Astros employee was removed from an area near the Boston Red Sox dugout during the AL Championship Series opener at Fenway Park last weekend. There were claims that the Astros had been trying to steal signs from opponents.

However, on Wednesday MLB said the Astros had been cleared of any wrongdoing. “With respect to both incidents regarding a Houston Astros employee, security identified an issue, addressed it and turned the matter over to the Department of Investigations. A thorough investigation concluded that an Astros employee was monitoring the field to ensure that the opposing Club was not violating any rules,” MLB said in a statement Wednesday. “All Clubs remaining in the playoffs have been notified to refrain from these types of efforts and to direct complaints about any in-stadium rules violations to MLB staff for investigation and resolution. We consider the matter closed.”

The Metro report said a man was removed during the third inning of Game 1 on Saturday night but allowed to stay in the ballpark after another Astros staffer intervened. The report said the man had a small camera and was texting frequently, but did not have a media credential.

Houston manager AJ Hinch and Red Sox manager Alex Cora both said after Boston’s 8-2 win on Tuesday night in Houston they had heard about the alleged incident.

“I’m aware of something going on, but I haven’t been briefed,” Hinch said. “I’m worried about the game.” Cora said he has been concerned throughout the season about Red Sox signs being stolen. “So I mean we do a good job changing sequences and paying attention to details. And we don’t get caught up on the whole paranoia thing of the signs,” he said. “We try to slow it down. If we feel there’s something going on we switch the signs.”

When asked if he felt like anything was going on the first two ALCS games at Fenway Park, Cora responded, “No, I don’t.”
