Regina Tarin Defeats JJ Aldrich by Unanimous Decision at Noche UFC

Regina Tarin delivered another dominant performance at Noche UFC on September 12, 2026, defeating JJ Aldrich by unanimous decision to remain unbeaten as a professional. All three judges scored the contest 29-28 in favor of Tarin, who controlled the striking exchanges from start to finish.

Tarin, nicknamed "Kill Bill," is now 9-0 as a professional and 2-0 inside the UFC at just 21 years old. The five-foot-seven southpaw has built a reputation as a high-volume striker, averaging 7.6 significant strikes landed per minute — a figure that puts her among the busiest fighters in the women's flyweight division. She lands at a 47 percent accuracy clip and has also shown a willingness to pursue grappling, averaging one takedown per fifteen minutes of cage time.

Aldrich entered the contest at 15-7 as a ranked flyweight, sitting at number 15 in the division. The 33-year-old southpaw stands five-foot-five with a 67-inch reach and had put together a two-fight winning streak heading into the bout. She averages nearly four significant strikes landed per minute with 47 percent accuracy, making her a technically sound opponent for any flyweight. The loss snaps that streak and hands her her first UFC defeat in two years.

Why it matters

• Tarin's perfect 9-0 record and youth make her an emerging force in the women's flyweight division
• A second consecutive UFC win could push Tarin into the divisional rankings for the first time
• The 29-28 scorecards across all three judges suggest a competitive fight, despite Tarin's clear striking advantage in volume
• Aldrich's loss at rank 15 may affect her standing in a crowded flyweight picture
