Despite taking the first set, Swiatek was outclassed by the Russian-born Kazakhstani, falling to a 3-6 6-1 6-2 defeat on No.1 Court.

Swiatek had to wait until the eighth game to undo Putintseva, earning her first break point before closing out the set in dominant fashion.

While many predicted Swiatek to hammer home her advantage, the Putintseva had other ideas.

She responded emphatically, cutting through Swiatek to battle into her first Round of 16 at Wimbledon and first at any Major since making the 2020 US Open quarter-finals.

Putintseva is the first women's player since Alison Riske against Ashleigh Barty in 2019 to win against the world No.1 at Wimbledon after losing the first set.

In stark contrast between the pair, Putintseva extended her win streak to eight matches after ending Swiatek's own run of 21 straight wins.

Swiatek still leaves the third Major of the year with an outstanding 45-5 record on the season, yet grass-court tennis and Wimbledon remain a troublesome issue for the Pole.

Jelena Ostapenko awaits in the clash for a last-eight position after the Latvian needed just 59 minutes to win 6-1 6-3 against Bernarda Pera earlier in the day.
