It was just one month ago on Dana White's Contender Series where Cam Rowston earned a UFC contract and called for a spot on UFC Perth. Now, not only did he earn that spot, but he made the most of it by putting away Andre Petroski during the preliminary card.

Petroski tried to get out on the front foot and take control right away, focusing on leg kicks. Rowston would try to get his hands going, and it worked, as a left hand resulted in Petroski getting knocked to the mat.

Following the fight, Rowston paid tribute to his teammate and mentor, former UFC middleweight champion Israel Adesanya, as he declared himself the new dog in the yard at middleweight.

Rowston has now won five straight, which includes his contract-earning performance on DWCS in a victory over Brandon Holmes.

Petroski, an alumnus of The Ultimate Fighter season 29, has now lost back-to-back fights after winning three straight.
