Today Mariano Rivera received a much deserved plaque in Monument Park at Yankee Stadium. The plaque commemorates his status as an all time Yankee great. What a pleasure it was to watch him pitch for 19 extremely succusful seasons as a Yankee. One could argue that he was the best closer to ever pitch in baseball. He was definitely the best closer that I have ever seen. I do not believe that we will see a pitcher of his caliber again for a long time, if ever.
