The read
Stiller has finished five of her six career wins by submission, which gives this a finishing dimension Cerminara hasn't often faced, but a short-notice UFC debut against a veteran of Cerminara's experience is a tall order.
Cerminara's game plan is almost always to keep the pace high and let the scorecards do the work, and that experience edge makes her the safer bet if the fight stays standing.
The matchup
This flyweight pairing changed on short notice after Jamey-Lyn Horth withdrew with an injury, bringing in UFC newcomer Mackenzie Stiller to face veteran former title challenger Katlyn Cerminara.
Stiller's judo-based submission game gives her a finishing path if she can get Cerminara to the mat, while Cerminara's volume and durability across a long UFC tenure have rarely been tested by an opponent making a UFC debut.
