Al Trautwig, who brought sports fans along with him to New York’s Canyon of Heroes, champagne-doused locker rooms and the medal podium at the Olympics over a broadcast career that spanned more than three decades, died at his home on Long Island on Sunday. He was 68.

His death was confirmed on Monday by his son, Alex Trautwig, who said that the cause was complications from cancer.

In the largest U.S. media market, one where no detail is too minute for newspaper back pages and sports talk radio, Mr. Trautwig was a familiar face on New York Rangers and Knicks broadcasts for a generation on MSG Networks. He also covered Yankees games before the team created its own cable network in 2002.

The son of Long Island had a wider audience: he covered 16 Olympics, most recently for NBC and focusing on gymnastics. His work earned him four national Emmys and more than 30 New York Emmys, his son said. He was also named New York Sportscaster of the Year in 2000.

Mr. Trautwig’s death was announced earlier on Monday by Alan Hahn, an ESPN Radio host and a studio analyst for MSG Networks, who described him in a social media post as a mentor and teacher.
