And then there were eight! The Round of 16 is in the books at the BNP Paribas Open, and on Thursday, all eight men’s and women’s singles quarterfinals matches will commence around the grounds. Before we look ahead to the tennis’ own version of March Madness, let’s take a spin back through the notable numbers that emerged during the fourth round. 

204 

The current ranking of Caroline Wozniacki, who has become the second lowest-ranked woman to reach the quarterfinals in BNP Paribas Open history, behind only Venus Williams, who reached the last eight in 1997 with a ranking of 211.  

11-2 

Emma Navarro’s record in three-set matches this season. The 22-year-old American pulled one of the biggest upsets of the tournament on Wednesday, defeating two-time Grand Slam champion Aryna Sabalenka 6-3, 3-6, 6-2 to reach her first 1000-level quarterfinal. 

150

The fastest serve of the tournament was struck by American Ben Shelton on Tuesday night, during his 7-6(4), 6-1 loss to Jannik Sinner. It’s the fastest, by far, at this year’s BNP Paribas Open. Milos Raonic (143) and Jiri Lehecka (142) are the silver and bronze winners in this category. 

33 

The age of Wozniacki, who is the oldest women’s singles quarterfinalist at this year’s BNP Paribas Open, and the seventh woman to reach the quarterfinals after turning 33. 

2010 

By reaching his maiden BNP Paribas Open quarterfinal, Norway’s Casper Ruud becomes the first Scandinavian man to reach the last eight since Robin Soderling in 2010. 

18

Jannik Sinner stretched his career-best winning streak to 18 matches with his straight sets win over Ben Shelton on Tuesday. The Italian is the first ATP player aged 23 or younger to start a season with 15 consecutive wins since Stefan Edberg in 1987. 

9 

Defending BNP Paribas Open champion Carlos Alcaraz is streaking as well. The 20-year-old has notched nine consecutive matches at Indian Wells and will face Alexander Zverev for a shot to reach the semis for the third consecutive year on Thursday. 

10 

Number of games dropped by Iga Swiatek all tournament to reach the quarterfinals. The Polish juggernaut has lost more than three games in a set only once this year. The 2022 champion improved to 15-2 lifetime at Indian Wells with her round of 16 win over Yulia Putintseva. 

Her scorelines thus far: 

Swiatek d. Collins 6-3, 6-0

Swiatek d. Noskova 6-4, 6-0

Swiatek d. Putintseva 6-1, 6-2

20

The age of Coco Gauff, Carlos Alcaraz, and Holger Rune the youngest players left in the singles Draw this year. 

99 –

Since the WTA 1000 level was introduced in 2009, 99 players have reached the semifinal stage. The winner of Anastasia Potapova vs Marta Kostyuk will be making their WTA 1000 SF debut, while Emma Navarro also has the chance to do so.
