I am a Red Sox fan, but when it comes to feats like Mariano Rivera’s setting a new major league record for saves, attention must be paid. I actually saw Trevor Hoffman, the previous possessor of that milestone, throw a perfect inning in Baltimore, nine pitches, nine strikes, three outs. It was glorious. And the Thursday before Labor Day, I saw Rivera absolutely destroy my Red Sox on the mound. That he’s done all this with essentially one pitch that no one’s ever managed to figure out is a testament to the great and profound mysteries of baseball.
