PHILADELPHIA -- It's one of those time honored baseball clichés that you never really know how good a player is until he faces some adversity.
No matter how much talent a rookie has, no matter how hard he has worked, and no matter how well he has pitched through the Minor Leagues, at some point the key will be the ability to handle adversity.
That's where Padres rookie Colin Rea, the No. 2 prospect in the Padres' system, finds himself after four major league starts, including Saturday's 4-3 loss to the Phillies.
