[allabout the $$$]

most dominant closer in baseball history. i would put the ball in his hands knowing he will get the job done over 90% of the time over almost 20 years in baseball. this is coming from a die hard mets fan who hates the yankees but i can respect all of the accomplishments he has attained in his career and he has done it the right way. cant really compare with the guys you have up there being that baseball is a team sport and federer and woods play individual sports
