Learner Tien reaches US Open fourth round after five-set win

Learner Tien remains undefeated in 5 setters by winning 6-3, 1-6, 6³-7⁷, 6-3, 6-4 vs Jakub Mensik It was a tough day for the Americans with Anisimova, Keys, and Fritz all losing but it ends on a high as Learner Tien wins a 5 setter and with his draw, may be the favorite to make Semis

Learner Tien becomes the youngest American man to reach the Round of 16 at the U.S. Open since Andy Roddick in 2002. His record in 5 set matches: 5 wins, 0 losses. It’s Tien Time. 🇺🇸

Newer tennis fans might not realize how remarkable that all four of the U.S. Open Round of 16 men’s singles matches today feature an American (plus Learner Tien tomorrow). Wasn’t that long ago that *zero* U.S. men made the fourth round here, in 2013, 2014, and 2019.

5 - With Learner Tien's victory over Jakub Mensik, 5+ Americans have reached the Men's Singles R16 at the US Open for the first time since 1995. Contingent. #USOpen

Learner Tien is moving on! 🇺🇸 The 20-year-old battles past Jakub Mensik in five sets, 6-3, 1-6, 6-7, 6-3, 6-4, to advance to the Round of 16 at the #USOpen. 🎾👏

I think it's really funny that Learner Tien and Jakub Mensik are wearing the exact same outfit down to the shoes though

eubanks with the hot take that learner tien has best chance of the US men to go all the way. I agree tien has shown the mental and physical endurance in high stakes, best of five matches—I’ve been talking him up this year w my coach— but youth (& time on court) might end up being the limiting factor

American singles players remaining at the 2026 US Open (WTA/ATP Rankings): Women 3. Jessica Pegula 4. Coco Gauff 14. Iva Jovic 27. Emma Navarro 96. Taylor Townsend Men 9. Ben Shelton 12. Frances Tiafoe 15. Learner Tien 21. Tommy Paul 46. Alex Michelsen 107. Michael Zheng

That was a hell of a game. Hello Learner Tien. Now I must sleep. #USOpen

I would turn over tables in the temples every day just to see a US male major champion and Auger-Aliassime win a major. I think Shelton and FAA each gets one by end of next year. I think Learner Tien can be there in a couple years. I think Tiafoe may be ready now.

Urggg I’d really rather watch Learner Tien not Zverevvvvv ???

I love the symmetry of the #14 men's and women's seeds at the #USOpen 🎾both being the Americans that are sort of sneaking up in the draw and into the consciousness of fans. For weekly tennis viewers, we've known all along, so it's nice to see both Iva Jovic and Learner Tien gain broader appeal.

How can you not root for Learner Tien? Love the guy

So many late nights during week one. Irvine's own Learner Tien moves on. 🌴
