Fourth-round action at the BNP Paribas Open concludes on Wednesday, as we build towards the quarterfinals. More enticing matchups are set to take place...including these five:

Coco Gauff vs. Belinda Bencic

Belinda Bencic has done a lot of winning in her career. The Swiss landed the gold medal at the 2021 Olympics, is a Grand Slam semifinalist and has spent much of her career inside the top 20.

But fully returning to the tour this year, she didn’t expect her comeback — Bencic became a mom last year — to go as well as it has. “But of course I'm going to take it,” said Bencic. “I'm very happy about it, and I feel like obviously it was a lot of hard work, to make the comeback.” Bencic entered Indian Wells inside the top 15 in the calendar year standings and picked up yet another victory on Monday as she turned 27.

Gauff, though, is one of the four players to get the better of Bencic in 2025, winning their fourth-round match at the Australian Open in three sets. And Gauff got some revenge Monday against Maria Sakkari, advancing in straight sets after the Greek won their semifinal in Tennis Paradise 12 months ago. The 2023 US Open champ did hit double faults — nine — but that number dropped from the 21 in the second round.

Carlos Alcaraz vs. Grigor Dimitrov

Last year’s bee swarm in the quarterfinal between Carlos Alcaraz and Alexander Zverev is having a lasting impact. A set of fans dressed in bee costumes attended Alcaraz’s straight set win against a rejuvenated Denis Shapovalov on Monday — and the Spaniard took note.

“It is funny, because it helped me a lot, because during the whole first set, I was looking at them and laughing,” said Alcaraz. “And I always say that when I’m laughing, when I’m having fun on the court, I show good tennis. So probably thanks to them I could show good tennis, as well.” Showing good tennis in Indian Wells is commonplace for Alcaraz, since he is the two-time defending champion.

But Grigor Dimitrov has beaten the four-time Grand Slam winner in their last two matches. The ever green 33-year-old ranked 15th is coming off a draining three hour win over his fellow thirty-something, Gael Monfils.

Madison Keys vs. Donna Vekic

Madison Keys’ section of the draw suggested that, on paper, the Australian Open winner would face fellow American Emma Navarro in the fourth round. They battled at the French Open last year in two tiebreaks, with Navarro getting the win prior to her even more eventful stints at Wimbledon and the US Open.

Asked about the 10th seed on Monday after her roller coaster win over Elise Mertens in the day session, Keys heaped praise on Navarro. “Emma is one of the grittiest players I think I have ever watched,” said Keys, riding a 14-match winning streak.

Donna Vekic, though, is gritty herself and the Olympic semifinalist showed it by battling past Navarro later in the night session. Her losing streaks, both in Indian Wells and generally in 2025, are over.

Speaking of tiebreaks, four of the last five sets Keys and Vekic played against each other went to tiebreaks. However, their last meeting came in 2019.

Taylor Fritz vs. Jack Draper

If their last three head-to-heads — all in 2024 — are anything to go by, then expect Taylor Fritz’s match with Jack Draper to extend to three sets. Fritz won two of them before Draper prevailed in Paris in October, creating 10 break points to two for the Californian.

That was months after both experienced a US Open high. Fritz made his first Grand Slam final and Draper got to the semifinals. “I think it's a tough draw to get him in the round of 16 as a top-four seed,” said Fritz, the 2022 champ in Tennis Paradise. “He’s a very good player. I think he's probably better than his ranking is, and yeah, we have had some tight ones.”

Every match for Fritz helps in his recovery from an abdominal injury. He had to rally against Alejandro Tabilo on Monday.

“I'm not going to feel as good tennis wise as I have been, playing a lot of tennis and super confident, just because I had to take some time off to get it better. I knew I was going to have to play myself kind of into the tournament, and I'm doing that."

Ben Shelton vs. Brandon Nakashima

Is San Diego’s Brandon Nakashima due for a win against Atlanta native Ben Shelton? Maybe, if you look at their past duels. While Shelton owns a 3-0 record and won all seven sets, all seven sets were either 7-6 or 7-5.

When they met in the first round of the Australian Open this year, Nakashima even led 5-2 in the first set and had five set points. Shelton rallied to take the set, match and got to his second Grand Slam semifinal before losing to the player who topped him last year in the desert, Jannik Sinner.

With Sinner absent in the desert, Nakashima became the last seed and thus got a bye. He’s won back-to-back matches in Indian Wells for the first time in his career and like Shelton, hasn’t dropped a set.

Along the way, Shelton ripped a 150 mph serve.
