Regina Tarin Defeats J.J. Aldrich at Noche UFC 4

Regina Tarin arrived in Las Vegas with an unbeaten record and a reputation as Mexico’s next flyweight hope. She left the opening bout of Noche UFC 4 still perfect, having just turned back one of the division’s most seasoned hands.

The 21-year-old prospect stayed composed and sharp across three rounds, earning a unanimous decision over J.J. Aldrich in the women’s flyweight curtain-raiser on Saturday. All three Sherdog scorers saw it 30-27 for Tarin, while the cageside judges went 29-28 across the board.

Tarin’s composure edges Aldrich’s experience

From the first exchange, Tarin refused to be overawed by Aldrich’s 17-fight UFC résumé. There was no glove touch, just an immediate technical duel in the center of the cage.

Aldrich opened with inside leg kicks and her familiar southpaw jab, trying to slow Tarin’s movement and establish rhythm. Tarin answered with her own low kicks and crisp counters, stepping into the pocket with three-punch flurries whenever Aldrich closed distance.

The Coloradan tried to break the youngster’s flow by changing levels, driving Tarin to the fence and working short shots to the body. The crowd quickly turned on the clinch battle, but Tarin quietly did the more damaging work at range, tagging Aldrich with sharp left hooks and clean counters as the round wore on. All three Sherdog scorers gave the opener to the Mexican prospect.

The second round belonged even more clearly to Tarin’s hands.

She literally pointed at the canvas and invited Aldrich into a firefight. Aldrich obliged, landing some solid right hands and a steady jab to the body, but Tarin’s responses came faster and in combinations. A stiff one-two, a left hook-right cross, then another right hand over the top whenever Aldrich kicked or tried to step in.

Aldrich’s attempts to wrestle were stuffed or stalled. One level change drew a knee to the body for her trouble. Tarin upped the tempo late, stinging Aldrich repeatedly and walking her down as the round closed, enough to bank another 10-9 on all three Sherdog cards.

By the third, Aldrich knew the situation. She needed something big.

Tarin, though, seized control of the center again and went to work with a three-punch combination upstairs, then mixed in rear-leg front kicks to keep Aldrich from setting her feet. When Aldrich did find success, it came in pockets—an elbow in the clinch, a jab on the break, a left over the top—but Tarin’s cleaner, straighter punches told the story.

Midway through the frame, Tarin split Aldrich’s guard with a nasty straight right and followed into the clinch. A clash left Tarin bleeding from the nose, yet she never stepped off the gas. Inside leg kicks, right crosses, left hooks—she met Aldrich’s late surge with her own fire and stuffed a last-ditch takedown as the final seconds bled away.

The result: a unanimous decision, Tarin moving to 9-0, and another veteran added to her growing résumé. On a night built around Mexican stars, the 21-year-old did exactly what a hyped prospect is supposed to do—handle business against a tough, durable test.

King announces himself with 36-second demolition

If Tarin’s win was about poise, Sean King’s debut was about raw violence.

The undefeated featherweight walked into his first UFC appearance against fellow newcomer Jessie Rosas and needed just 36 seconds to make a statement that echoed around the division.

No feeling-out process. No handshake. King went straight to work with a thudding body kick, then chopped at Rosas’ lead leg twice, forcing him to react. As Rosas adjusted, King closed the distance, locked his hands around the body and lifted.

What followed was the kind of slam that changes careers.

King hoisted Rosas high and drove him into the canvas with enough force to knock him out on impact. As Rosas lay stricken, King squeezed in a few follow-up punches before referee Brad Frank could dive in, sealing a KO by slam and punches at 0:36 of the opening round.

In less than a minute, King moved to 7-0 and turned a routine debut into a highlight that will live on every Noche UFC reel for years. Tarin provided the polish. King brought the chaos. The rest of the card suddenly had a high bar to clear.
