UFC Vegas 121 gave the strawweight division a new face and the middleweight ranks a milestone night, according to Ag. Fight. Our own results archive has it as a TKO (punches) in Round 2 at 3:19 at UFC Vegas 121, and it earned Black her official spot on the UFC strawweight roster. Black wasted no time putting the rest of the 115 pound division on notice. "I bring danger," she said, a line that fits a fighter who just stopped an unbeaten opponent on the biggest stage of her career so far. On the same card, Rodolfo Vieira turned his birthday into a win. The Rio de Janeiro middleweight turned 37 the day of the official weigh in, then backed it up one day later with a unanimous decision over Poland's Robert Bryczek. The numbers behind that win matter for where Vieira sits in the division. Our Elo model has him at 1524 across seven UFC bouts, well clear of Bryczek's 1457 built over four fights, and the result lines up with that gap. For Bryczek, who drops to that same 1457 rating after the loss, it is a step back in a short UFC ledger. For Black, the story is just starting. A finish of an undefeated foe to win a TUF season is the kind of result that puts a new strawweight straight on the radar of the rest of the division, and after her post fight message, she clearly wants everyone watching.
