Gwynn, who turned 40 in 2000, had a left knee injury that required his knee to be drained seven times before he underwent season-ending surgery. He was limited to playing just 36 of the Padres' first 71 games, and he started only 26 games in right field. He batted .408 from May 19 to June 23 to raise his average from .196 and finish the season at .323. Gwynn had microfracture surgery performed on his knee, which involved tiny holes being created to promote cartilage growth.
