“I never thought I would ever do this because in this industry you’re usually told when to leave. But in this case, everyone was so kind and understanding,” he continued.

Castiglione said he would continue to serve in an “ambassadorial role” and appear at events on behalf of the team.

In a statement released by the team, John Henry, principal owner of the Red Sox (and owner of the Globe), called Castiglione “one of baseball’s greatest commentators.”

“His recognition by the Hall of Fame in July was the culmination of a career filled with vivid storytelling that brought the game to life for generations of listeners. His brilliance in the announcer’s booth is matched only by his extraordinary character. Although his role placed him squarely in the spotlight, he always kept the action on the field at the center, a trait he demonstrated even behind the microphone with his uncanny ability to put others first. His kindness and genuine spirit touched everyone around him, and as he enters a well-deserved retirement, he leaves behind a legacy of humility and warmth that will continue to inspire us all. We are grateful for his more than four decades of dedication and for sharing his love of baseball and the Red Sox with all of us night after night.”

The Connecticut native was honored this summer by the Baseball Hall of Fame with the 2024 Ford C. Frick Award, the Hall’s highest honor for sportscasters.

Castiglione has been calling Red Sox games since 1983 and is the franchise’s longest-serving commentator. Working with partners such as Jerry Trupiano, Bob Starr, Dave O’Brien, Flemming and Sean McDonough, Castiglione has provided the soundtrack for so many iconic Red Sox moments.

His “Can you believe it?” chant as the Red Sox ended an 86-year drought and won the 2004 World Series is considered one of the most memorable.

Castiglione ended his speech in Cooperstown last July with this sentence.

“Joe is part of it,” said David Ortiz, a member of the Red Sox Hall of Fame, at Castiglione’s induction. “You can’t think of the Red Sox without thinking of Joe.”

Castiglione was inducted into the Red Sox Hall of Fame in 2014. In 2023, he reduced his role to 81 games to spend more time with his family. His wife, Jan, sons Tom and Duke (of Channel 5), daughter Kate and six grandchildren ages 10 to 18 were present for his honor in Cooperstown – along with dozens of other friends, family members and former players.

The Red Sox end a four-game series against the Yankees in New York. Tyler O’Neill hit a two-run home run in the fourth inning – shortly after Castiglione announced his retirement.

“This,” said Flemming, “is for Joe.”
