In the first match of the 2026 ATP Tour season, World No. 45 Sebastian Baez defeated Jaume Munar to give Argentina a 1-0 lead over Spain on Day 1 of the United Cup in Perth Friday.
Making his debut at the mixed teams event, the 24-year-old recorded a 6-4, 6-4 win against the Spaniard in one hour and 43 minutes in the Group A tie. With the victory, he improved to 2-0 in the pair’s Lexus ATP Head2Head series.
“I really enjoyed this moment, enjoyed the time on court, so happy to [have] won this point for Argentina,” he said.
After both players traded breaks early in the first set, Baez gained control at 4-4 by breaking Munar and serving out the set in the following game. In the second set, the Argentine showed great composure again by breaking back, immediately after losing serve, for a 4-3 lead. He saved four of the six break points he faced in the match, according to Infosys ATP Stats.
“I am happy because I am recovering from some pain and some injuries from the past two years. So, of course, I want more. I know I have more. I have some confidence and I believe in my team and in my country,” Baez shared.
With the victory, the Argentine secured his first Top 50 win since defeating then-No. 46 Mariano Navone on his way to the title in Rio last February.
