Even though there is no greater sports rivalry, last night the Boston Red Sox paid tribute to New York Yankees closer Mariano Rivera, in his last regular season appearance at Fenway Park.

The 43-year-old Rivera has said he will retire after this season, his 19th in the major leagues, all of them with the Yankees. He has 651 career saves - tops in baseball history - with a 2.22 ERA and even the rival Red Sox called him the greatest closer in baseball history.
