If you had to finish a sentence that involved the words “greatest closer of all time,” then any other name attached to that sentence besides Mariano Rivera is going to spark a huge debate. A debate that will most likely end up with you being just flat-out wrong, but a debate nonetheless. So to honor Mo as his final season is just now about halfway in the books, New Era found it fitting to create five different limited-edition commemorative caps. The hats each feature embroidered logos on the front, side, and rear that all pay tribute to Rivera and his long, dominating career as a Yankee. You can purchase yours HERE or at the New Era Flagship store.
