A 1987 draftee out of Los Alamitos High School by the Texas Rangers, Robb Nen made his major league debut in April, 1993. Over the course of a 10-year major league career, he saved 314 games for the Marlins and Giants. In 2000, he finished 4th in the Cy Young balloting, and 12th in the MVP race. The following year, he led the National League in saves with 45, and finished out 71 games, a major league record that stands to this day.
The all-time leader in saves for both the Marlins and the Giants, Nen's career was derailed in 2002, when a surgery to "clean up loose particles" in his pitching shoulder revealed a torn labrum. In a younger pitcher, a condition which often necessitates ulnar collateral surgery (aka, Tommy John surgery).
