At the conclusion of each round at the 2023 BNP Paribas Open, we take you inside the numbers to shine a light on some of the most significant statistical achievements taking place around the grounds. With the action just winding down, we take you through for a quarterfinal recap, by-the-numbers…

1 – Number of teenagers to reach the semifinals

Carlos Alcaraz is the teenage wunderkind at this year’s BNP Paribas Open. The 19-year-old advanced on Thursday with a win over Felix Auger-Aliassime as the new era of tennis superstars continues to thrive in Tennis Paradise.

3 – Number of Semifinalists yet to drop a set at the 2023 BNP Paribas Open

Iga Swiatek, Carlos Alcaraz and Frances Tiafoe are scorching-hot as they prepare for the last four.

10 – Length of Iga Swiatek’s Current BNP Paribas Open Winning Streak 

The World No. 1 continues to run the table flawlessly at the BNP Paribas Open. On Thursday, she sauntered past Romania’s Sorana Cirstea 6-2, 6-3. Swiatek has won her last 16 sets at Indian Wells, and has dropped just 19 games at this year’s event.

4 – Number of three-setters won by Maria Sakkari (in as many matches)

Maria Sakkari has been walking the tightrope all tournament long in the California desert, but last year’s runner-up doesn’t want to leave Tennis Paradise. After rallying from a set down for her first two wins to reach the Round of 16, she surged back from a break down in the third set to take out No.17-seeded Karolina Pliskova for her second consecutive trip to the Indian Wells quarterfinals. On Wednesday, she upped the ante yet again, completing a brilliant rally to knock off two-time Slam champion Kvitova.

No lead is safe against Sakkari right now.

47 – Years of Waiting Ends For Italian Men at Indian Wells 

Italy’s Jannik Sinner is the first Italian man to compete in the semifinals in the tournament’s 47-year history. He edged past defending champion Taylor Fritz 6-4, 4-6, 6-4 on Thursday, earning his third career Top 5 win.

44 – Swiatek Extends Domination Against Players Outside the Top 50 

Not since Croatia’s Ana Konjuh took out Swiatek at the Miami Open in 2021. has the Polish juggernaut been upset by a player who didn’t hold a Top 50 ranking. Another amazing Iga stat.

30 – All Eight Men’s Singles Quarterfinals Were Under 30

It’s the first time all men’s singles quarterfinalists have been under 30 at the BNP Paribas Open since 2008. The game is getting younger. Cameron Norrie, who will turn 28 in August, was the oldest. Carlos Alcaraz, who turns 20 in May, is the youngest.

18 – The length of Daniil Medvedev‘s current winning streak

How does he do it? Swollen ankle, bloodied hand, challenging conditions. Nothing seems to be able to stop Daniil Medvedev from doing what he does best – winning.

2 – A Number Nine Years in the Making 

For the first time since 2014, the top 2 seeds on the women’s side have reached the semifinals. Nine years ago Li Na and Agnieszka Radwanska both reached the semifinals – and the final. This year No,-seeded Iga Swiatek and No.2-seeded Aryna Sabalenka are holding it down in the California desert.
