In the UFC 307 co-main event Saturday at Delta Center in Salt Lake City, Peña (13-5 MMA, 8-3 UFC) defeated Raquel Pennington (16-10 MMA, 13-6 UFC) by split decision (48-47, 47-48, 48-47) to win the promotion’s women’s bantamweight title.

Pena outworked the titleholder over five rounds to wrestle back the championship she lost to Amanda Nunes two years ago

Julianna Peña became just the second two-time champion in UFC women's bantamweight history on Saturday, but did so by the narrowest of decisions. Peña (11-5) took the belt from defending champion Raquel Pennington (16-9) via split decision in the co-main event of UFC 307 inside Delta Center.
