The Red Sox announcers (who I like a lot better) weave commercials into their commentary, but it's not as bad as the way the Yankees' announcers do it.
I don’t remember it being as bad last year.
Maybe when they get off the hook for A-Roid, they can cut back on the ads ;^)
On the Pirates broadcasts, the disclaimer (any rebroadcast or retransmission of the descriptions or accounts of this game....)is now sponsored by a law firm!
