Cora said the situation is something for Major League Baseball to handle. His final two starts consisted of a combined four innings and 58 pitches.
There was no indication of any suspicious activity during Game 3 in Houston on Tuesday night, but the Red Sox were careful to change their pitch-calling signs throughout the night - something Manager Alex Cora said is fairly standard for the Red Sox.
A separate report from Yahoo Sports identified the man as Kyle McLaughlin and says he aimed a cell phone into the Indians' dugout during their Game 3 loss to the Astros in the AL Division Series. Moments after his slam, fans at TD Garden in Boston began chanting "JBJ!" during the Celtics season opener against the Philadelphia 76ers. Bregman's double was the only extra-base hit for a team which entered the game having hit at least one homer in a record 14 straight playoff games.
The Red Sox and Indians may not have been the first targets of a sign-stealing effort.
When presented with the details of the incident and the warning given to security heading into Game 1, a Red Sox spokesman said on Tuesday, "It is an Major League Baseball matter, so no one from the Red Sox would be commenting". "And he kept showing up. Now you see the results".More news: Gruden: Raiders not looking to trade Amari Cooper
McLaughlin is said to be the same man who was discovered by security at Fenway Park with a camera in a credentialed area near the Red Sox dugout during Game 1 of the ALCS.
The Red Sox lead the best-of-seven series 2-1.
"MLB significantly beefed up its security presence at Game 3 on Tuesday, according to a league source with knowledge of its staff, sending three people from its baseball-operations office and another six security personnel to monitor the game", Passan wrote.
Pearce almost delivered an extra-base hit with two on in the third, but 5-foot-6 left fielder Tony Kemp jumped at the wall and came up with Pearce's towering fly. He was replaced by Rafael Devers.
"That's a completely different inning if he hits that ball a foot further or if Tony can't get up on the wall and make that catch", Houston manager AJ Hinch said.
"It did hit the wall, but it was actually in my glove at the time", Kemp said.
