I think you would have to factor the DH into those numbers. At first glance it appears that only Cabrera and Frank Robinson spent a lot of their final years there, and that reduced the wear and tear they would have had by playing the field every day (IMO). That said, Miggy's OPS had dropped into the 600's by 38, but Frank's was still in the .solid 800's at the end. Junior was still playing the field at 38. when his OPS was .738. So you can't draw any conclusion from that. As we get a larger sample size of the players affected by the DH, while Soto and Vlad will be moving toward the end of their careers, the numbers may be more predictive. I hope Soto, if he is still a Met, will have numbers closer to Robby and Junior than to Miggy. Time will tell. Later
