He retired for good in 2007 after spring training with the Yomiuri Giants.

Quinn split the 2001 season between right field, left field, and designated hitter. His production at the plate dropped to 17 homers and a .269 average due to nagging hamstring injuries.

During 2003Spring Training, Quinn was released by the Royals after going just 1-for-8 in his appearances and suffering another setback with his hamstring.[2]
