Outside of New England, he is probably best remembered for his time as CBS's lead baseball announcer, a role in which he was teamed with Tim McCarver. In 1992 at the age of 30, he became the youngest man to announce the national broadcast (and all nine innings of all of the games played) of the World Series. Coincidentally, that particular record would be broken four years later by Fox's 27-year-old Joe Buck, the son of the man McDonough replaced on CBS, Jack Buck.
