Jeff Hamilton was signed by the Los Angeles Dodgers and scout Dale McReynolds as a 29th round pick in the 1982 amateur draft. He was part of the 1988 World Series champion team, and in 1989 he was sixth in the National League in doubles. Hamilton started at third base on June 3rd that year but finished the game as the pitcher, when he took the loss in the 22nd inning against the Houston Astros. It was Hamilton's only pitching appearance. The game also finished with future Hall of Famer Eddie Murray at third base in place of Hamilton and pitcher Fernando Valenzuela manning first base. It was to be 19 years before Jamie Burke became the next major league position player to be charged with a loss.
Hamilton hit over .300 as a minor league player between 1983 and 1992, with a peak in 1987 when he hit .360 in 65 games. He also pitched successfully in the minors, going 10-3, mostly in Single A ball.
