The 88-year-old announcer tells the Los Angeles Times his Hall of Fame career will end Oct. 2 in San Francisco. Scully had already said this will be his final season in the booth after 67 years, but until Tuesday had not announced whether he planned to call any potential postseason games on radio.
Scully says if he stayed on the air, he would be "saying goodbye like in grand opera, where you say goodbye 12 different times."
His decision was not a surprise to the team, Dodgers spokesman Joe Jareck says.
Scully has two farewells coming up: First, on Sept. 25 during the Dodgers' final home game of the regular season and then a week later at San Francisco.
Looking for their first World Series appearance since winning the 1988 championship, the Dodgers ended the night with a four-game lead in the NL West over the Giants.
Scully switched from television to radio in recent years during the playoffs, when national broadcasters have exclusive TV rights.
Not this time.
"I'm going to say goodbye at Dodger Stadium the last game with Colorado. I will say goodbye in San Francisco. And then that will be it," he told The Times.
