6. Mariano Rivera (Panama)
Every opposing team who plays in Yankee Stadium dreads the sound of Metallica’s “Enter Sandman”: that’s the music that comes on the PA when Mariano Rivera, the greatest and most consistent relief pitcher of all-time, is called in from the bullpen. Rivera’s reputation as an unflappable stopper has even even made him a reference point in hip-hop lyrics. See Jay-Z’s “More than a relief pitcher, I’m the closer/The Mariano of the Marriott” line from Young Jeezy’s “Go Crazy.”
