Sandman tribute -- New Era is capping off Mariano Rivera's career nicely

Mariano Rivera got quite the sendoff from Major League Baseball during his retirement tour, and New Era has capped off Mo's retirement season pretty nicely.

The baseball cap company presented the first of 42 limited-edition 59FIFTY Yankees caps to Mr. Sandman himself and is offloading the remaining 41 caps to fans. The hat is white with navy blue pinstripes and has a Yankees logo and Mariano Rivera patch on the front.

The side of the cap features images of the five World Series rings Rivera won during his 18-year career with the Yankees. The box the hat comes in is pretty cool, too.
