For most Giants radio broadcasts onKNBR,Jon Miller andDave Flemming take turns callingplay-by-play (usually Miller will call innings 1-2, 5-6, 8-9, and Flemming will call innings 3-4, and 7). The Giants' telecasts onNBC Sports Bay Area andKNTV featureDuane Kuiper as play-by-play announcer withMike Krukow ascolor analyst.
Through 2010, Miller held a second job as play-by-play announcer forESPN Sunday Night Baseball, and therefore usually missed weekend Giants games. On these occasions,Greg Papa would take Miller's place on either the television or radio side; however, on weekends when the Giants were featured onFox television (Saturday) or ESPN (Sunday) and therefore not on local TV, Kuiper and Krukow would join Flemming on the radio, and Miller would generally work the Saturday game if ESPN was in San Francisco that weekend. Since leaving ESPN, Miller also calls select games on NBC Sports Bay Area.
On July 14, 2006, for a Friday night home game, Flemming made his television broadcast debut for the Giants. Since then, Flemming and Kuiper have taken turns calling games on the radio and on NBC Sports Bay Area (Flemming calling innings 1-3, 7-9, and Kuiper calling innings 4-6 on the radio; and vice versa on TV) whenever Miller is off. Similarly, Miller and Kuiper also take turns on KNBR and NBC Sports Bay Area (Miller calling innings 1-3, 7-9, and Kuiper calling innings 4-6 on the radio; and vice versa on TV) when Flemming is off. During most road games, Flemming will call innings 1-3 and 7-9 on NBC Sports Bay Area, while Miller will call 4-6 (and vice versa on KNBR). On road trips when Kuiper comes, it would be like a normal home game unless Flemming is gone, so either KNBR will bring in Joe Ritzo or if the game is on national television, Kuiper will call the game with Miller.
After every game all of the announcers come together on the radio side for the "post game wrap", recapping the game's key plays and selecting players-of-the-game in humorous fashion.
F.P. Santangelo, formerly with the Washington Nationals, assisted Flemming on some broadcasts, and retired broadcasterLon Simmons (died 2015) was usually present several times a season. Since May 2007, and only during weekend home games and road games against the A's, retired Giants first basemanJ.T. Snow has performed color analyst duties alongside Flemming. In the 2010 season, Doug Greenwald (son of former Giants broadcasterHank Greenwald and regular announcer for the AAA (Fresno Grizzlies) called several Giants radio broadcasts as a substitute for Flemming. Former Giants reliever Jeremy Affeldt joined Kuiper for a radio broadcast on September 15, 2016.
Joe Ritzo andF.P. Santangelo are currently the fill-ins on KNBR when Kuiper, Miller, and/or Flemming are off/on TV.Shawn Estes,Javier Lopez, andHunter Pence fill in for Mike Krukow when he is off.
Spanish-language radio broadcasts are handled byErwin Higueros, who calls the play-by-play, andTito Fuentes, who performscolor analyst duties.Marvin Benard also serves as a color analyst for road games.
Over the years, the Giants have employed numerous other on-air broadcasters, includingHall of FamersRuss Hodges andLon Simmons, as well asAl Michaels,Hank Greenwald,Ron Fairly,Lindsey Nelson,Ted Robinson, andJoe Angel, among others in English, andAmaury Pi-Gonzalez, in Spanish.
