On 9 March 2019, Ugás fought his first career title fight against Shawn Porter for the WBC welterweight title. Ugás fought great and landed the cleaner shots throughout the fight. Porter had some success with his jab in the fourth round, but Ugás was the better man in the following round, after both fighters exchanged shots in the middle of the ring towards the end of the fifth. Ugás also had a stronger finish to the fight, and managed to cut Porter near his left eye in the tenth. After the final bell rang, Ugás' team already started celebrating, while Porter just stood and looked at his corner. To many of the fans' surprise, two of the judges scored the fight in favor of Porter, 116–112 and 115–113, while only one of the judges scored the fight in favor of Ugás, 117–111. The crowd was booing what seemed to many as a controversial split decision win for Porter.[9]

In his next fight, Ugás dominated former world champion Omar Figueroa to a unanimous decision win, winning every round in the process. All three judges scored the fight 119–107 for the Cuban, who only had one point deducted for holding in the fifth round.[10]

In his following fight, Ugás fought Mike Dallas Jr. Ugás boxed well and managed to hurt Dallas Jr on multiple occasions. After the seventh round, Dallas Jr's corner had seen enough and informed the referee he would not be continuing the fight.[11]

On 6 September 2020, Ugás fought Abel Ramos for the vacant WBA (Regular) welterweight title. Ugás outboxed Ramos, dominating most of the rounds throughout the fight. This earned Ugás a split decision victory, with one judge scoring the fight 117–111 for Ramos, while the other two had it narrowly for Ugás, both scoring it 115–113.[12]

On 29 January 2021, Ugás was elevated to the status of WBA (Super) champion after the previous title-holder, eight-division champion Manny Pacquiao, was stripped of his title due to inactivity.[13] The latter had been scheduled to face undefeated WBC and IBF champion Errol Spence Jr. on 21 August 2021 at the T-Mobile Arena in Las Vegas, until Spence had to withdraw due to suffering an injury to his left eye. Subsequently, Ugás took Spence's place, and made the first defense of his WBA (Super) title against Pacquiao.[14]

The bout was a competitive affair, with Ugás using his jab and looping right hand effectively to control the distance. While Pacquiao had moments of success throughout the night, he never truly settled into a rhythm and was noticeably stiffer than usual, not showcasing the deft footwork that he has been known for throughout his career. Pacquiao himself admitted after the fight that his legs were "tight". At the final bell, Ugás was awarded a unanimous decision victory with scores of 116–112, 116–112 and 115–113.[15] According to CompuBox, Pacquiao threw over double the number of punches compared to Ugás, but landed fewer, making the latter the far more accurate boxer on the night. Pacquiao landed 130 punches of 815 thrown (16%), while Ugás landed 151 punches of 405 thrown (37.3%).[16]

After successfully defending his title against Pacquiao, Ugás petitioned the WBA for a special permit to bypass a mandatory defense against Eimantas Stanionis in order to face the IBF and WBC champion Errol Spence Jr. in a title unification bout.[17] The petition was denied by the WBA on 20 October 2021, who stated: "...we are in special circumstances to resolve extraordinary situations, such as the champion reduction in every division to have only one champion". Accordingly, Ugás and Stanionis were given a 30-day period to negotiate the terms of their bout.[18] As they were unable to come to terms, a purse bid was ordered for 9 December, with a minimal bid of $200,000. The winning bid would be split 75/25 in favor of Ugas as the reigning titlist.[19] On 19 December 2021, WBA President Gilberto J. Mendoza has confirmed that the Spence-Ugas was approved as Stanionis was willing to step aside.[20] The unification bout was officially announced on 8 February 2022. It was scheduled to headline a pay per view card on 16 April, which took place at the AT&T Stadium in Arlington, Texas.[21] The PPV was distributed by Showtime.[22] Ugás lost the fight by a tenth-round technical knockout. The fight was stopped on the advice of the ringside physician, due to Ugas’ severely swollen right eye. He was losing on all three of the judges' scorecards at the time of the stoppage, with scores of 88–82, 88–82 and 88–83.[23] Ugás landed fewer total punches (216 to 96) and fewer power punches (192 to 77) than Spence Jr.[24]

On March 16, 2023, the WBC ordered Ugas to face the former WBA (Regular) super lightweight champion Mario Barrios for the interim welterweight championship.[25] The title bout took place at the T-Mobile Arena in Las Vegas, Nevada on September 30, 2023.[26] Barrios won the fight by unanimous decision.[27]
