sorry, but that's a real heartbreaker and shocker in both cases.
Nook and Jack were two of the more interesting stories of the baseball year, and I'm personally saddened to hear the news in both cases. While I never got on the Jack train (and still think the a's are consciously self-destructing out of spite), Nook was/is an exciting young player who really helped make the Nationals a pleasure to watch (and a holy terror for Mets fans).
The really sad thing is that one wonders about just a few months ago - did Cust have chemical help in his super slugger summer? Was Nook incredibly fast on the bases for more than one reason?
The older guys don't bother me at all for some reason, but seeing the minor league cinderella and the fastest young guy in the NL get named is a bummer.
