Dricus Du Plessis remains the king of the middleweight division, submitting former two-time champion Israel Adesanya by rear-naked choke in Round 4 to retain his title Saturday in the main event at UFC 305 in Perth, Australia.

Du Plessis wore Adesanya down with his relentless pressure and strikes and got the tap at 3 minutes, 38 seconds.

Du Plessis (22-2) won his 10th straight fight and was coming off a split decision over Sean Strickland in January to win the 185-pound title. Du Plessis entered as the No.1 middleweight in ESPN’s rankings.
