Leonard had an otherwise routine career as a spare outfielder, mostly in the National League, except for his performance in the 1987 postseason for the San Francisco Giants. In the National League Championship Series he belted four home runs and had ten hits. He angered the opposing St. Louis Cardinals with his home run trot. Leonard would run around the bases exceedingly slow with one of his arms down by his side in an awkward circuitry of the diamond. He called it “flap down,” which became his nickname. In spite of his slugging exploits, the Giants lost the NLCS to the Cardinals, but Leonard was named MVP, becoming the first player on a losing team to win the honor.
- Leonard had tremendous success against Tim Lollar, who pitched mostly for the Padres. In 34 career at-bats against Lollar, he hit .471 with three home runs and an .882 SLG.
