Happy Birthday, Mariano Rivera! Here's to the man who perfected closing games—so much so, opponents probably still flinch when they hear "Enter Sandman." Your cutter was nastier than coach's dugout coffee and smoother than your pinstripe uniform. Yankees fans everywhere celebrate each year remembering how effortlessly you secured over 600 saves; honestly, we suspect even Superman would struggle against that pitch.It's amazing how retirement hasn't slowed down your legend one bit—you were unanimously elected into Cooperstown faster than a batter swinging at strike three! Wishing you another wonderful year as timelessly impressive (and intimidating) off-field as you've always been on it!
