"Coming to the Majors at the young age of 19, I hit .310/.340/.451 with 17 steals in 90 games. I never really got any better than that. . .which means I was still a damn good player, even if some people were disappointed. I made four All-Star teams, won several Gold Gloves. From the age of 27, I had a hard time staying healthy, which limited me to bench work (though good bench work) after the age of 30. Who am I?"
