Second Round action continues at the BNP Paribas Open on Saturday. That means more of the seeds in action. Here are five matches to watch, led by a 24-time Grand Slam winner.

Novak Djokovic vs. Botic van de Zandschulp

When the draw came out earlier this week, eyes were drawn to Novak Djokovic and a possible second round blockbuster with Nick Kyrgios. The now good friends played doubles together in Brisbane this year and met in the 2022 Wimbledon final.

But they won’t share the court, since an emotional Kyrgios retired Thursday night due to continuing issues with his right wrist. Djokovic instead meets a lucky loser — and one with a giant killing reputation, Botic van de Zandschulp.

The Dutchman beat Carlos Alcaraz at last year’s US Open, then beat an even heftier Spaniard, Rafael Nadal, in November in what turned out to be Nadal’s final match. A lucky loser, Luca Nardi, stunned Djokovic 12 months ago in Tennis Paradise. Djokovic says he is healthy after injuring his hamstring against Alcaraz in Melbourne, and coach Andy Murray joined him in the desert as their high profile partnership continues.

“Other than Slams, few tournaments that really give me inspiration when I wake up in the morning and think about where I want to do well. Indian Wells and Miami are definitely at the top of that list,” the 37-year-old said, referring to the next leg of March’s Sunshine Double.

“I'm excited to be here and with Andy on board. Hopefully we can have a great month in the States.” Djokovic eased past van de Zandschulp in 2022 in their lone previous matchup, conceding only four games.

Aryna Sabalenka vs. McCartney Kessler

Despite results not going her way in the last few weeks, it hasn’t all been gloomy for Aryna Sabalenka. The women’s No. 1 attended a post Oscars party and “loved it.” Sabalenka wants to get back to winning ways, though, and land the BNP Paribas Open crown for the first time. She came close in 2023, losing the final to Elena Rybakina after hitting 10 double faults.

“I felt like I kind of like lost that match on my own,” said Sabalenka. “I just made a lot of unforced errors, and I kind of let that game go her way.

“To win this trophy would mean a lot, because I had a lot of crazy experiences here at Indian Wells, and I always wanted to win this tournament. “It would be incredible to have this beautiful trophy in the house.”

One of those crazy experiences came last year, when Sabalenka saved four match points to down Peyton Stearns in her opener. She meets another American with a forehand that can do damage in McCartney Kessler.

Coco Gauff found that out first hand in Dubai, when Kessler up- set the 2023 US Open winner for a maiden top 10 win. The Georgia native has soared to inside the top 50 this year thanks to winning her second title and making the final in Austin last week.

Madison Keys vs. Anastasia Potapova

Anastasia Potapova spent two hours, 40 minutes on court in the first round against Spain’s Jessica Bouzas Maneiro in a match that produced 36 break points. Potapova got the last two breaks and they were important, as the scrappy World No. 34 prevailed 7-5 in the third set after trailing 5-3.

Madison Keys, on the other hand, hasn’t played a match since edging Sabalenka to win her first Grand Slam title at the Australian Open in January. She had more reason to celebrate last month, turning 30. “I had a little bit of time at home to kind of reset, get back to practice, do a little bit of rehab and get back to 100 percent,” said the Florida resident, who sports a 1-1 record against Potapova. “Really looking forward to starting the swing in the States.”

Carlos Alcaraz vs. Quentin Halys

Carlos Alcaraz won his second straight title last year, so it might be easy to forget that he entered the tournament under a cloud. Alcaraz lost to Alexander Zverev in the Australian Open quarterfinals and suffered an ankle injury on clay. When he also dropped the opening set against Matteo Arnaldi in his first match, things looked a little bleak.

But the four-time major champion only lost one more set, capping his stay in Tennis Paradise with another win over Daniil Medvedev.

Quentin Halys owns one of the biggest serves in tennis, averaging about 14 aces per match this season (excluding a retirement). The 28-year-old from France comes in at a career high No. 59, just reaching the biggest semifinal of his career in Dubai and posting his first Top 10 win.

Taylor Fritz vs. Matteo Gigante

Taylor Fritz loves to get on court and is well known for playing through pain. He did it in the 2022 final against Nadal, overcoming an ankle injury to win the biggest title of his career in his home state.

But Fritz felt the time was right to take a little break recently, pulling out of Acapulco with an abdominal injury. “Eighty percent of my game is pain free,” said Fritz. “It’s just the other 20 percent that kind of stops me from playing 100 percent. That's why I decided to pull out of Acapulco, because probably could have forced myself through it.”

If he isn’t at his peak, does opportunity knock for Matteo Gigante? With a ranking of 217th, the left-hander defied the odds just to get through qualifying (beating van de Zandschulp to reach the main draw). The 23-year-old didn’t stop on Thursday, upsetting the gritty Sebastian Baez to notch a second career ATP win.
