Invoking Occam's razor, Campos says "the simplest explanation is that there is no crisis...
...current crop of rookie hurlers the best in baseball history? Consider: Marlins righty Anibal Sanchez, 22, left, threw the first no-hitter since '04 last week--and he's not the top prospect on his team. The rooks have pitched some clubs into contention and look primed to pile up Cy Young awards. Here's the most dazzling of the baby-faced bunch...
