Unseeded Ethan Quinn opens his US Open 2025 campaign against Swiss qualifier Jerome Kym. Quinn, who turned professional in 2023, briefly touched a career-high world ranking of No. 81 last week and enters New York at No. 84. His season has been marked by early exits, rarely moving past the second round, but he has shown glimpses of potential. The American reached the Challenger Canberra final, the Challenger San Diego semifinals, and most notably the third round of Roland Garros, where he pushed Talon Griekspoor to five sets before bowing out. Statistically, Quinn has fired 157 aces this season, winning 70% of first-serve points with a 44% break-point conversion rate, though his 28% first-serve return mark remains an area of concern.

Kym, meanwhile, has been carving his path on the Challenger circuit. The 21-year-old turned professional in 2019 and lifted two Challenger titles last season at the Czech Open and Zagreb, adding three more from the ITF level earlier in his career. While a title has eluded him in 2025, Kym has compiled a series of semifinal runs across Gstaad, Mauthausen, Zagreb, Vicenza, Modena, and Hagen. His numbers reflect a serve-heavy game, producing 36 aces and winning an impressive 80% of first-serve points. However, his efficiency drops on return, winning only 20% of first-serve return points and converting just 36% of 14 break point opportunities.

My journey into sports media began far from the field, rooted in the arts and sciences. Funny enough, I didn’t grow up a sports fan; I used to see it all as just noise. But a fateful writing job introduced me to the world of sports, and what began as a gig quickly became a passion. I understood those voices aren’t noise; they’re emotions of true sports fans, and now I am one of them, writing with the same energy I once questioned.
