Winning Wimbledon was a highlight of a difficult last season for Swiatek – a theme that has continued into this year.
She has not won a major since her SW19 triumph last year and has yet to win a title in 2026.
Eala, meanwhile, has been on the rise since Miami and won the WTA 125 title on the Birmingham grass courts in the build-up to Wimbledon.
A star in her home country, Eala has the pressure of her nation on her shoulders every time she walks on court – and she made a nervous start against the former world number one.
The pair could not be separated in a tight first set after an early exchange of breaks, although momentum was with Swiatek as she stopped Eala serving the set out at 5-3 and forced a tie-break.
Brilliant rallies were followed up with errors but Eala, gesturing for more noise from the crowd following a superb rally, clinched the opener on a long Swiatek forehand.
Swiatek yelled at her box before going off court to reset, only to quickly find herself 4-0 down.
Her quality dipped in and out as she rescued one of the breaks and gave it away in the next game, and then put Eala under pressure as she served for the match – only for the Filipina to be the braver of the pair on the break points.
Swiatek finished the match with 44 unforced errors and five double faults to one ace, with the final point fittingly being a long forehand from the frustrated Pole.
Eala – the first player from the Philippines to reach the fourth round of a Grand Slam in the Open era – will face 2024 runner-up Jasmine Paolini next.
