NBC Sports revealed on January 22 that Costas has joined the new MLB team as the host of the official Sunday Night Baseball pregame show, which will preview the game ahead each evening and look at the larger baseball landscape for the week. 

“We’re excited that Bob has agreed to come home to NBC Sports, where he helped make baseball an iconic brand earlier in his career for so many years,” said Rick Cordella, President, NBC Sports. “There is no more knowledgeable, authoritative and passionate voice on baseball than Bob Costas.”

Costas has won 29 Sports Emmy Awards in his decades-long career, and in 2018 he received the National Baseball Hall of Fame and Museum’s Ford Frick Award for excellence in baseball broadcasting. His career includes World Series, NBA Finals, Olympic games, and countless hours of baseball, including serving as the play-by-play voice of the MLB Network since its launch in 2009. He previously hosted 15 seasons of MLB coverage on NBC, and now he’s back in the chair for Sunday Night Baseball. 

“As appreciative as I am of other aspects of my career, especially HBO and the MLB Network, for 40 years, my true broadcasting home was NBC,” Costas said. “So many great moments, memories, and friendships. Now, I am very grateful to Rick Cordella and Sam Flood for inviting me back in an emeritus role to conclude my career where so much of it played out.”
