LOL at that RoY candidates list. Yordan's got nearly the same absolute numbers as any of them in literally half the games. And 63 points higher in batting average over the next closest contender.
The problem here with the announcing is that Berkman is acting as the play-by-play announcer relegating Esch to the color role. Not that Esch is good at PBP or color; it's just a matter of who's talking the most. Not the best.
