Iga Swiatek's remarkable streak of winning at least one Grand Slam title every year since 2022 is over, after China's Qinwen Zheng pulled off one of the most stunning comebacks of the season to eliminate the world No. 2 in the US Open's fourth round on Monday.

Zheng trailed 0-5 in the opening set at Arthur Ashe Stadium before reeling off seven straight games to steal it 7-5, then closed out the match 6-3 in the second set, sending Swiatek to a straight-sets defeat that ended her tournament, according to Yahoo Sports. The Ashe Stadium crowd, initially squarely behind the heavily favored Swiatek, turned electric as Zheng's comeback gained steam, roaring through the closing games of the first set and carrying that energy into the second.

A Pattern of Comebacks

It was the second straight match in which Zheng erased a 5-0 deficit — she pulled off the same feat in a third-set comeback against Madison Keys just days earlier. The win also made Zheng the first qualifier to reach the US Open quarterfinals since Britain's Emma Raducanu's stunning title run in 2021, a comparison that's already generating buzz around the rest of her draw.

IT'S JUST ONE MATCH

Swiatek, visibly emotional as she left the court, tried to downplay the loss afterward, telling reporters she didn't want to overanalyze a single result. But the numbers tell a bigger story: since claiming her first major at the 2022 French Open, Swiatek had never gone a full calendar year without lifting at least one Grand Slam trophy — a run now officially snapped with the 2026 season's final major slipping away, per ESPN.

The upset was one of several that rattled the bottom half of the women's draw on Monday. Naomi Osaka's bid for a fifth major title also ended in the same round, dominated by Elena Rybakina, while seeded players kept falling one after another across the draw.

For Zheng, the win is the latest marker in a breakout run that's included an Olympic gold medal and now a run to her first US Open quarterfinal. She'll face a red-hot field with genuine momentum, having already knocked out two of the tournament's most decorated competitors inside a week. For Swiatek, the loss means an early flight home and an offseason that will inevitably invite scrutiny of her hard-court game — long considered her relative weak point compared to clay. She's expected to regroup on the fall hard-court swing before turning attention to next year's Australian Open, where she'll look to restart the streak that carried her through four consecutive seasons.
