Prior to UFC 271, Tai Tuivasa was just a big man with a fun gimmick. The 28-year-old Australian heavyweight had won four fights in a row, but with none of those wins having come against a ranked opponent, Tuivasa was best known for his signature victory celebration: drinking beer out of a shoe — a shoey.
Then Tuivasa went out at UFC 271 and got by far the biggest win of his career — a second-round knockout of Derrick Lewis, the UFC’s career knockout king and a two-time participant in title fights. Lewis went into the fight at No. 3 in the ESPN heavyweight rankings.
Now, for the first time, Tuivasa is ranked among the best in the world. That’s something worthy of a toast.
