Four to Six Weeks. Six to Eight Weeks. Hell, just say eternity, for that's what it will seem like for #45 to return.
We have witnessed this in the past that he is strong on the mound when at the top of his game, but can be as fragile as balsa wood and snap. And, the reparation period to me seems to be akin to gluing a dropped vase. The parts may all be there, but congruency is ruined. It takes a few weeks for him to regain his form. Ostensibly, what can we do, but pray he gets better quickly and that the doctors are overestimating his condition to be cautious.
Whenever I think of bad breaks in pitching, David Clyde, Todd Van Poppel, Brien Taylor and a slew of others, it just simply makes me shudder. Pedro is a fantastic pitcher, but now is not the time for him to be hurt.
I think managers must make the players more accountable for fitness and flexibility - but that is a whole 'nother topic for the next time.
