You be the judge. So far only bloggers have picked up this story, but I think by the evening you'll see mention on ESPN at least. The footage of last night's game shows Rivera clearly looking down at the ball and hucking a loogy on it, then throwing a pitch.
Does this explain why that cutter cuts? Have we found the fountain of youth? I'm sure there will be more to this story.
