Berchelt needed 11 rounds when the pair met in January 2017, but he was far more convincing in Tucson, Arizona.

The 27-year-old was relentless and had Vargas bleeding before the latter's corner called an end to the fight after the sixth round.

Berchelt (36-1) won his title in the pair's initial bout, and he has now defended successfully five times to extend his winning streak to 15.

"He gave me a shot to win my title, I wanted to give him a chance to win it back," he said after his win.

"His corner did the right thing by stopping the fight."
