Except for 1995, when he missed 11 weeks with a broken wrist, Ken Griffey Jr. was a relatively healthy and highly productive player in his first 11 major league seasons, all of which were spent with the Mariners. But since 2000, after he moved to the Reds, Griffey has been severely hampered by physical ailments, including a dislocated shoulder and a ruptured ankle tendon that limited him to 53 games last year. Using its PECOTA system (which projects a player's numbers based on up to 100 statistically comparable players), the website-thinktank Baseball Prospectus projected Griffey's stats from 2000 onward based on the assumption that he was injury-free. (The PECOTA system is fairly conservative and accounts for the fact that even without a catastrophic injury Griffey was likely to miss an increasing number of games each year because of his advancing age.) Baseball Prospectus estimates that in those four seasons Griffey lost 280 hits, 70 home runs and 194 RBIs.
