On September 29, 1996, Chris hit what would prove to be a game-winning, two-run, pinch-hit double in the top of the 11th inning against Los Angeles Dodgers pitcher Chan Ho Park to complete a three-game sweep of the Dodgers and clinch the Padres' second National League Western division championship in history. Chris hit two pinch-hit walk-off home runs during his career.
He lives in California with his wife JoAnn, his son Joshua Christopher Gwynn, and his daughter Maya JoAnn Gwynn.
