Seniesa Estrada enjoyed every second of her long-awaited return to the ring Saturday night in Las Vegas.

The undefeated Estrada relentlessly threw punches at Jazmin Gala Villarino and fended off the aggressive Argentinean contender in their 105-pound title fight at Palms Casino Resort’s Pearl Concert Theater. Judges Max DeLuca, Chris Migliore and Patricia Morse Jarman all scored it a shutout, 100-90, for East Los Angeles’ Estrada (23-0, 9 KOs), who won a unanimous decision and retained her WBA minimumweight championship.

Buenos Aires’ Villarino (6-2-2, 1 KO) lost for the first time since her four-round pro debut by majority decision in November 2016.

The 30-year-old Estrada ended a lengthy layoff that lasted almost 11 months. She was signed to a multi-year promotional deal by Bob Arum’s Top Rank Inc. in July after a contractual dispute resulted in a split with Oscar De La Hoya’s Golden Boy Promotions.

Estrada was in complete command by the 10th and final round Saturday night, but that didn’t stop Villarino from pressing forward and landing her fair share of power shots during the final two minutes of action. Estrada had built an insurmountable lead through nine rounds, though, and Villarino clearly couldn’t affect the defending champion with any of her punches.

Estrada caught Villarino with a right uppercut and then a left-right combination with just over 1:10 remaining in the eighth round. Backed against the ropes later in the eighth round, Estrada connected with a left-right combination up top after drilling Villarino with a right to her body.
