Room only exists for one.

Sergio Pettis will put his Bellator MMA bantamweight crown in the line against interim titleholder Patrick Mix when their unification bout co-headlines Bellator 301 on Friday at Wintrust Arena in Chicago. The championship has been fractured since April 2022. Pettis enters the cage with the wind of six-fight winning streak at his back, having established himself as one of the organization’s pound-for-pound standouts. The Roufusport rep last appeared at Bellator 297, where he retained his half of the title with a unanimous decision over Patricio Freire on June 16. Mix, meanwhile, has rattled off five straight victories. He last competed on April 22, when he cut down Raufeon Stots with a first-round knee strike at Bellator 295 to win the promotion’s $1 million bantamweight grand prix and the interim championship.

As Pettis and Mix move ever closer to their looming showdown at 135 pounds, a look at some of the numbers that have accompanied them to this point:

30: Years of age for Pettis, who was born in Milwaukee on Aug. 18, 1993.

4: Pettis wins by knockout or technical knockout, accounting for 17.5% of his career total (23). His list of victims: Kyoji Horiguchi, Dillard Pegg, Tony Zelinski and Kyle Vivian. Pettis owns four other wins by submission (17.5%) and 15 more by decision (65%).

924: Days spent by Pettis as Bellator bantamweight champion. It ranks as the longest title reign in the history of the company’s 135-pound weight class, just ahead of Eduardo Dantas (911 days).

77: Rounds started by Pettis as a professional mixed martial artist. He has gone the distance on 18 different occasions and carries a 15-3 record in those bouts.

142: Combined victories between the six men—Freire, Horiguchi, Juan Archuleta, Ricky Bandejas, Alfred Khashakyan and Tyson Nam—Pettis has defeated since he last suffered a setback. They boast a cumulative .770 winning percentage at 142-42-1.
