For his career, Trammell was a six-time All-Star selection, a four-time Gold Glove winner, a three-time Top 10 MVP, and a three-time Silver Slugger Award winner. In 2001, Trammell was rated as the ninth best shortstop of all time in "The New Bill James Historical Baseball Abstract," rating him higher than fourteen Hall of Fame shortstops.

Four years later he became the bench coach for the Arizona Diamondbacks.
