Dave Sims, who has spent the past 20 years calling Mariners games, will replace John Sterling as Suzyn Waldman's play-by-play partner on Yankees radio broadcasts.

Dave Sims will be the lead broadcaster for Yankees games on WFAN Radio, taking over for the retired John Sterling.

Sims, known for signature calls such as “Hey now” and “Giddy up, baby,” has been the Mariners’ television play-by-play man since 2007. The Philadelphia native will now join the 78-year-old Suzyn Waldman, Sterling’s longtime broadcast partner, in the Yankees’ radio booth. WFAN is close on a deal to hire Dave Sims as John Sterling’s replacement.
