Harold Reynolds and Tom Verducci will join Joe Buck in the announcers' booth for Fox's Major League Baseball coverage this season.
Tim McCarver retired after the World Series as the network's top color commentator.
Reynolds had been a studio analyst for MLB Network since its launch at the start of 2009. He was fired by ESPN in 2006 after a decade with the network.
Verducci had served as a reporter for TBS's baseball playoff coverage since 2008 and worked previously for Fox and with Reynolds at MLB Network.
The trio will make their debut April 5 for a Giants-Dodgers game on Fox Sports 1.
