Vernon Wells took a solid step towards a productive major league career in 2002. He played regularly, handled centrefield with flair and hit for more power than might have been expected. But he didn't walk much, so there is the inevitable concern in sabrmetric circles about his development as a hitter. What can we expect from Vernon in the upcoming years?
To address this question, I needed to identify a comparable group of young ballplayers to find clues about what the future has in store for Vernon. I approached it systematically, paring down the players based on (what I think are) reasonable criteria. First, I looked at all major league position players born 1969 though 1978 and noted their career numbers though their age-24 season (for 1969 players, 1993 is their age-24 season; for the 1978 players it is 2002). It's usually not a good idea to go too far back with age-comparisons - in some cases, what results is a comparison to what players did in very different eras. I chose 400 plus PA as my threshold, since that seemed like a reasonable sample, but still allowed a fairly large number of players to be included in the study. There were 130 such players.
