On March 23 local time, the women's singles fourth round matches of the 2026 WTA1000 Miami Open fully commenced. The spotlight match of this round unfolded between Chinese star Zheng Qinwen and defending champion Aryna Sabalenka. After a fierce battle lasting 1 hour and 25 minutes, the latter won in straight sets 6-3/6-4, updating her season record to 20 wins and 1 loss.

Zheng Qinwen
Miami is the third tournament Zheng Qinwen has participated in since her comeback this season. She performed well in the first two matches, defeating Grand Slam champions Stephens and Keys to reach the Round of 16. In the fourth round, Zheng faced the test of her longtime opponent Sabalenka. The world number one holds a 7-1 lead in their head-to-head record and remains undefeated against Zheng on hard courts.
In this match, Sabalenka quickly converted two breaks to lead 5-1 at the start. Although Zheng saved two break points and managed one break back, she still lost the first set 3-6. In the second set, Zheng, who was broken in the third game, had three consecutive break opportunities in the eighth game, but Sabalenka saved them all, shifting the balance of victory towards the latter.
Compared to previous encounters, Zheng Qinwen adopted a more proactive strategy in this match against Sabalenka, striving to take the initiative in their baseline exchanges. Throughout the match, Zheng hit 21 winners and 28 unforced errors, exceeding her opponent by 6 and 13 respectively. In serving statistics, Zheng's 8 aces and 5 double faults showed an aggressive pattern; despite an impressive 83% first-serve win rate, a mere 40% first-serve success rate posed potential issues.
Although unable to advance further, by reaching the Round of 16 and earning 120 ranking points and $105,720 in prize money, Zheng Qinwen's live ranking climbed back to No.30. She will rest for two weeks next, starting her clay season campaign at the WTA500 Stuttgart event.

Aryna Sabalenka
For Sabalenka, this marks her 20th win this season, extending her winning streak at this tournament to 9 matches. Having reached at least the quarterfinals in 15 consecutive events, she is now just 3 wins away from achieving the "Sunshine Double" feat. In the quarterfinals, Sabalenka will face local player Baptiste, who eliminated No.25 seed Ostapenko 6-3/6-4.
In other fourth-round matches, No.4 seed Gauff again battled through three sets, defeating Romanian veteran Cirstea 6-4/3-6/6-2 to achieve the "full quarterfinals" milestone in WTA1000 events. No.5 seed Pegula swept No.34 seed Christian 6-4/6-1, reaching the quarterfinals here for the fifth consecutive year.

No.12 seed Bencic spent 78 minutes to defeat locally playing No.6 seed Anisimova 6-2/6-2, returning to the tournament quarterfinals after 4 years, and will face another American, Gauff. No.10 seed Mboko defeated No.8 seed Andreeva 7-6(4)/4-6/6-0; No.13 seed Muchova swept popular Philippine player Eala 6-0/6-2. The two winners will replay the Doha final in the quarterfinals.
