In the new setup, Kalas will be situated on television with Chris Wheeler and former Phillie Gary "Sarge" Matthews.
The trio will broadcast the first three and last three innings on television. Wheeler will handle play-by-play in the middle three innings, with Matthews as the analyst.
Kalas will continue to call the fourth inning on radio. Scott Franzke and Larry Andersen will work exclusively on radio.
Flyers television announcer Jim Jackson will be the pre- and postgame host on radio.
Now entering his 37th season with the Phillies and a member of the Baseball Hall of Fame, Kalas says the extra man in the booth won't change his approach to broadcasting the games.
"I will keep doing the same thing," he said. "They can play off each other, and I can play off both of them."
While purists may feel three is one too many in a baseball booth, Wheeler and Matthews worked well together in the televised exhibition games.
Wheeler knows the players and their tendencies as well as any analyst in the game. He also has the ability to work well with a partner, integrating him into the broadcast.
Matthews has shown during the exhibition season not only a great knowledge of the game, but also a nice delivery, showing excitement, but not going overboard.
With Wheeler and Matthews, there won't be a lot of joking, but plenty of baseball talk, explaining the strengths and weakness of players while also going over the strategy.
Of course, that doesn't mean there won't be an adjustment period.
"Three men in a booth is kind of a work in progress, and you feel your way along," Wheeler said. "But I think we can both add things to a lot of situations."
Both Kalas and Wheeler have high expectations for Matthews.
"He brings the knowledge of a player, a coach, and he also did broadcast work with Toronto," Kalas said.
