I'll give you some more names: Zambrano, Prior, Wellemeyer, Leicester, Wuertz, Beltran, Mitre. Those are all players that came through the system in the last 3-4 years that played a major part in the season. There are even more if you include players like Juan Cruz that we traded away. Mitre only got a few starts but he will get more this season. Beltran got some and then was a major part of the deal for Garciaparra. That's a pretty good amount of talent to come through any team. The Cubs are different from the Devil Rays because they don't have to rely on their farm system as much due to the higher payroll. Yet, at the same time, prospects are used in trades to acquire more experienced players. There are more ways than just playing time for a farm system to improve a team.
