On October 8, 2011, Lee participated in the "100 Innings of Baseball Game" hosted by the Boston Amateur Baseball Network to raise money for ALS (Lou Gehrig's Disease). On August 23, 2012, Lee pitched a nine-inning complete game for the San Rafael Pacifics in San Rafael, California, beating the Na Koa Ikaika Maui 9–4. Using a homemade bat in the fifth inning, he drove in the first run of the game for the Pacifics. Lee was signed to a one-day contract by Pacifics' President and General Manager Mike Shapiro. Lee's bat and uniform were donated to the Baseball Hall of Fame following the game as the start gave him the record for the oldest pitcher to make a starting appearance, pitch a complete game and also to earn a win in a professional baseball game.
