As of 2020, Joe Buck is Fox's lead play-by-play commentator (a role he has held since Fox inaugurated its Major League Baseball coverage in 1996), with John Smoltz serving as color analyst; they are joined by field reporter Ken Rosenthal, and during select regular season and postseason games, Tom Verducci. From 1996 to 2013, Buck was teamed with Tim McCarver, although McCarver was considered the main reason behind the firing of Jack Buck from CBS five years earlier (due to poor on-air chemistry between the two) in favor of Sean McDonough. Unlike the team of Jack Buck and McCarver on CBS, Joe Buck and McCarver fused. According to McCarver, "The play-by-play man explain what and where and analyst answer why and how. [Joe Buck does both." During the pre-2001 period, Bob Brenly (who otherwise, typically worked with Thom Brennaman) acted as the third man in the booth with Buck and McCarver during the All-Star Game, League Championship Series and World Series. Buck and McCarver were at the microphone when Brenly led the Arizona Diamondbacks as manager to the 2001 World Series title. Since Joe Buck was hired to work on the "NFL on Fox", following the retirement of lead play-by-play voice Pat Summerall in 2002, Dick Stockton, Kenny Albert, Matt Vasgersian, Thom Brennaman, Josh Lewin, and others have filled in for Joe Buck whenever he is unable to work a game.
