Well, not quite, but the erstwhile Yankee radio man and SportsCenter anchor is off to Chavez Ravine, where he'll replace Ross Porter and share a booth with Rick Monday for Dodger broadcasts; they will alternate with Vin Scully, who works alone. From MLB's report:

Steiner, a New York native, said the first game he heard on a big Zenith radio at the age of 6 had Scully calling the Brooklyn Dodgers from Ebbets Field.

Link via Bookworm, who speculates that beat reporter Suzyn Waldman may take Steiner's place in the booth; I'm fairly certain she'd be the first woman to broadcast games on a regular basis for a New York baseball team.
