Looks like ESPN is bringing in their own guy to call the races...Larry Collmus. Good choice. I always liked the guy.

"Hats off to my golfing partner Larry Collmus, the voice of Monmouth Park, who’ll be calling Zenyatta’s next race for ESPN, and once again he’ll be Trevor Denman’s Breeders Cup back-up at Churchill Downs.
Undefeated in 18 career starts, the great Zenyatta is scheduled to race in the Grade 1 $250,000 Lady’s Secret Stakes at Hollywood Park on October 2.
I’m very happy for Larry, who’s such a dedicated and respected professional."
