He hit three home runs in a game twice that season, both coming in Cubs losses. The first was a slugging duel with Mike Schmidt on May 17 at Wrigley Field; Kingman hit three home runs and drove in 6 while Schmidt hit two in the game, with Schmidt delivering his second in the top of the tenth inning to give the Phillies a 23-22 victory. Kingman's third home run during this game is likely the longest home run of his career, and believed to be the longest in the history of Wrigley Field. There is a street called Kenmore Avenue that T's into Waveland Avenue behind left-center field. Kenmore is lined with houses, and the ball Kingman launched landed on the third porch roof on the east side of Kenmore, a shot estimated at 530 feet."
