When ​Mariano Rivera got the call and found out he was a ​Hall of Famer, the celebration was underway. The entire ​Rivera family lost it when they found out Mo became the first player in history to receive 100 percent of the vote. 

Couldn't have happened to a nicer guy. 

​​Rivera joined former Toronto Blue Jays ace Roy Halladay, Seattle Mariners legend and arguably the greatest DH ever in Egdar Martinez, and the ultra-consistent Mike Mussina in Cooperstown. 

Not only is Rivera the greatest closer of all time, but the gap between him and the second best closer ever is as cavernous as the Grand Canyon. 

Rivera's 2.21 ERA, 652 career saves and unmatched success in the postseason, paired with a calmness and tranquility that just doesn't come along that often, makes him the greatest reliever who ever picked up a glove. 

​​After such a legendary career, Rivera deserves all of the accolades coming his way. And then some.
