Zheng Shocks Marozsan; Shelton & Tiafoe Charge On

Listen, if you thought college tennis players couldn't cut it on the big stage, you need to open your eyes. Columbia wildcard Michael Zheng just put on an absolute clinic in Queens, dismissing world No. 63 Fabian Marozsan 6-4, 6-4, 6-2. Despite a frustrating weather delay that threatened to derail his match momentum, the 22-year-old local favorite kept his composure on his US Open debut, painting lines and showing the kind of attitude I love to see on a tennis court.

Zheng was utterly relentless from the baseline, firing 33 winners to just 17 unforced errors. He played with a chip on his shoulder, refusing to let the officiating or the humid conditions break his focus. You've got to be kidding me if you didn't see the tension on Court 17—this kid is the real deal.

Shelton and Tiafoe Survive the Pressure Cooker

While Zheng was taking care of business, the established American stars had to battle through absolute dogfights. Ben Shelton showed serious guts on the grandstand, outlasting Hubert Hurkacz 6-3, 5-7, 7-6 (3), 7-5. Shelton's massive serve got him out of several tight spots, but it was his mental toughness during the third-set tiebreak that ultimately tilted the scales.

Meanwhile, Frances Tiafoe booked his ticket to the third round for a seventh straight year by holding off Rei Sakamoto 6-3, 7-6 (2), 7-5. Much like Jessica Pegula's clinical victory over Sofia Kenin, Tiafoe relied on his experience on the pressure points when it mattered most.

Rivalry Matchup & Player Profiles

This victory extends Zheng's perfect head-to-head record against Marozsan to 2-0, according to the latest ATP rankings. Zheng's aggressive baseliner style completely disrupts Marozsan's rhythm, allowing the young American to control the court geometry and dictate play.

While both are hunting for their first career titles, Zheng's performance shows he has the ceiling to climb far beyond his current standing. If he keeps hitting spots like this, the rest of the draw better watch out.
