I think someone a few posts up hit the nail on the head. To answer Skippy's original question about why many baseball players seem to marry so young, I think athletes, as well as other types of celebrities gravitate towards the high school sweetheart or the person that loved them before they became "the star" They want someone who they can trust who isnt just after the name or the money. Some of these marriages end in divorce sure but thats a chance anyone takes not just ballplayers.
Off topic question but most of the Nats seem to have pretty good marriages. Are any of the guys divorced or ever had any relationship scandals?
