The Read
O'Malley is a long, rangy switch-stance striker whose game is built on distance, feints and a precise lead-hand snipe — UFC.com credits him with roughly 61% significant-strike accuracy and 6.05 significant strikes landed per minute, elite output for the division. At his best he turns fights into a shooting gallery, picking opponents apart at the end of his 72-inch reach and dropping them with right hands and up-the-middle knees, as he did against Aljamain Sterling and Marlon Vera. The questions have always been about volume wrestling and grappling under pressure rather than his hands.
Those questions were answered the hard way by Merab Dvalishvili, who beat O'Malley twice in 13 months — a one-sided decision at UFC 306 (O'Malley fought with a torn labrum) and a third-round submission in the UFC 316 rematch, where he was outlanded and worn down by relentless takedown pressure. He steadied the ship in January 2026 with a close unanimous-decision win over Song Yadong at UFC 324, rallying late after a slow middle stretch. Against Aiemann Zahabi at Freedom 250 he is the sharper, more proven striker on paper; the live question is whether the back-to-back losses dulled his aura and whether Zahabi's counters can exploit the moments O'Malley stands still.
