Posted by Scoops: Tonight in Tampa, Fla., New York Yankees closer Mariano Rivera saved his 300th career game. It is hard to compare players from era to era in baseball, or any sport for that matter. But you heard it here: Mariano Rivera is the best relief pitcher in the history of baseball. There is always debate over which pitcher you would want to start the hypothetical game No. 7 of the World Series, and I do not want to broach that topic. But if I were a manager, and you gave me the option of handing the baseball to one pitcher to record one out to win that game No. 7, I would not hesitate to say that my man would be wearing jersey No. 42, and be wearing pinstripes. I guess this is open to debate. Some may say Dennis Eckersley, some may say Tug McGraw. But I want Mo.
