Berkman diagnosed with Grade 2 strain of left calf muscle and will be rested for two to three days. He is available to pinch hit.
Grade 2? Huh?
Well, let's look:
Grade 1: Minor degree of microscopic tearing with no permanent defect
Grade 2: Incomplete disruption of muscle fibers, which is also called a partial tear
Grade 3: Complete rupture of muscle, with nearly complete or complete loss of muscle function
And this site says a Grade 2 strain means...
between 10 to 50% of the muscle fibers are torn. While the muscle is not completely ruptured, grade 2 muscle strains are still serious and will take time to heal.
There you have it (quiet sobbing).
