There have been a few deviations from that. And ESPN will formally announce Monday that it will experiment Monday night on its Los Angeles Dodgers at St. Louis game (7 ET). ESPN will keep play-by-play announcer Dan Shulman in the booth, but analysts Orel Hershiser and Steve Phillips will be stationed in the camera wells beside each dugout.

Matt Sandulli, ESPN senior coordinating producer, says the Cardinals preferred ESPN use the camera well on the outfield side, rather than home plate side, of its dugout to reduce chances its analysts might somehow interact with players. Sandulli says that won't happen anyway — "we're not supposed to talk to players and wouldn't do it" — and hopes to get the Dodgers to allow access to the well on its dugout's home plate side.

TV sports commonly station reporters along sidelines, in pit road or on golf fairways. But putting main game announcers in separate locations rarely has been done, such as NBC's Pierre McGuire being rinkside on NHL games or ESPN having Paul Maguire chime in on football from a sideline camera cart. Says Sandulli: "There's lot of non-verbal communication in the booth. We joked that maybe (the analysts) will will send signals from dugout to dugout."

Sandulli says its possible that ESPN could send more baseball announcers out of the booth on future games, depending partly on whether Monday night's experiment delivers a "wow factor."
