In 1990, the Reds went to the postseason for the first and only time in Browning's career. He won 15 games that season and picked up a key win over the Pittsburgh Pirates in Game 2 of the National League Championship Series. The Reds would meet the heavily favored Oakland A's in the World Series that year, but thanks in part to Browning's victory in Game 3, the Reds pulled off an unlikely sweep to become world champions. "That 1990 season was, without a doubt, the most enjoyable season of baseball I has ever been a part of," he said.
