Drysdale did pre and postgame interviews for the final game of the ALCS at Fenway Park, in his last assignment for ABC. He did p-x-p for the network's Sunday afternoon games, which aired until July, when 'Monday Night Baseball' began. (Michaels did the main Sunday game, usually with Jim Palmer, while Drysdale and Johnny Bench did the backup contests). Keith Jackson(usually working with McCarver) did the # 2 Monday night games. Bench took a week off in June(with Steve Busby filling in), and also worked one game with Michaels as the networks switched the announcer pairings. Drysdale worked the All-Star game as an interviewer, and did not resurface til the playoffs. Bench simply disappeared, ultimately going to CBS radio.
Although Michaels, Palmer and McCarver had done the '85 World Series together, ABC did not team them on a regular basis on 'MNB' until 1988(after three 'experiments' in 1987).
But it would had made more sense to have Drysdale do the NLCS with McCarver, and let Jackson do CFB instead.
