Recently, Costas has called games for MLB Network and TBS Sports, concluding his run with the American League Division Series between the New York Yankees and Kansas City Royals. Though his contract with TBS ended this season, his decision to retire from play-by-play had been planned for over a year, with The Athletic breaking the story. Costas is expected to speak about his choice at a later time.
Costas, a longtime baseball enthusiast, called games on NBC from 1982 to 1989 and again from 1994 to 2000. He covered the 1995 World Series and was the main voice for the Fall Classic in 1997 and 1999.
He joined TBS in 2021 as a studio host for the National League Championship Series and called games over the past three seasons. Since 2022, TBS has aired Tuesday night regular-season games along with postseason coverage.
In addition to TBS, Costas has called games on MLB Network since its launch in 2009. He will continue to contribute to MLB Network for special events, including the Baseball Hall of Fame announcements.
