American Ethan Quinn secured his biggest career title Sunday at the Arizona Tennis Classic, an ATP Challenger 175 event in Phoenix. In an all-American final, the eighth seed downed Marcos Giron 7-6(1), 4-6, 7-5. “It’s surreal,” Quinn said following his triumph, his second at ATP Challenger level and first since November 2024. “It’s not every day that you get to be in the final. I feel like it’s been a while since I’ve been in a final, getting to compete late in a tournament, so all the emotions are really high.” #ATC2026 #ArizonaTennisClassic #ATPChallenger #TennisInTheValley #Phoenix
