Main draw action kicked off on a bright, sunny day at the Indian Wells Tennis Garden, with 16 first-round matches taking place across the grounds.

Scroll down for a rundown of Wednesday’s action.

Berrettini Survives

Italy’s Matteo Berrettini had to give everything to earn his first hard-court win of the season. Literally, everything.

The former World No. 6 had to delay his celebration after his 4-6, 7-5, 7-5 win over Frenchman Adrian Mannarino due to a sudden bout of cramping that hit him as soon as the match ended.

“He has given EVERYTHING to this contest,” said Robbie Koenig, who was commentating on the match.

Berrettini battled for two hours and 48 minutes to earn his fifth career win in the California desert.

Afraid to move, the Italian lay prone on the court for six minutes before he could get to his feet. During that time Mannarino stopped by to check on him and shake hands, then the doctors arrived to look in on the World No. 66.

When he finally got the all clear, he headed to his chair to rest, before conducting a few post-match interviews.

“I fought really hard until the very last point,” a relieved Berrettini said. “At the beginning of the third, I started to feel like a little bit cramping. I was a little bit surprised at the beginning, and then I remembered that I was sick until three days ago, so that's why I was like, ‘Okay, that's normal.’”

“That's what we do, we adjust, we try to fight our best, and that's what I did today.”

Despite the difficult sensations, Berrettini still managed to crack 23 forehand winners and win all 12 points he played at the net to defeat Mannarino for the first time in three tries.

Crucially, Berrettini saved the only break point he faced in the final set and scored a break in the final game to earn the victory — before collapsing on the court.

“I found the way to pull through,” said the 29-year-old, who will face No. 4 seed Alexander Zverev in the second round. “I was serving well, hitting well, and that's why I'm happy.”

Monfils Keeps The Dream Alive

39 and feeling fine. Gael Monfils prolonged his final appearance in Tennis Paradise with a 6-3, 6-4 win over Canadian qualifier Alexis Galarneau. The former World No. 6 becomes the fifth man in tournament history to make 17 or more main draw appearances in the California desert and also etches his name into the tournament record books as the second-oldest match winner at Indian Wells, after Ivo Karlovic, who reached the round of 16 at age 40 in 2019.

The Frenchman will face ninth-seeded Canadian Felix Auger-Aliassime in the second round.

“It’s a great feeling,” an emotional Monfils said after the win. “Their energy was phenomenal. I'm just blessed and very thankful. I had a great performance, but, you know, it was a hell of a crowd tonight.”

After falling behind by a break in the opening set, Monfils got the wake-up call and took control of the match. He still had to work for the win. The Frenchman saved a pair of break points when serving out the opening set, then survived a trade of breaks in the second before pulling away and winning the final three games from the World No. 219.

Monfils, who made his debut in the Coachella Valley 21 years ago in 2005, remembers being wowed by the site and all it had to offer as a teenager. He still feels that way now as he plays the event for the final time.

“Tennis Paradise, you know?” he said. “It's unbelievable. I came here in 2005 for the first time with my mom. I was a kid, and with my mom, we were amazed by the beautiful atmosphere. Of course there are a lot of memories that I will keep in my heart.”

Shapovalov edges Tsitsipas in battle of former Top 10 talents

Denis Shapovalov and Stefanos Tsitsipas gave the Stadium 1 faithful their money’s worth and more in the final match of Wednesday night’s session. In a battle of former Top 10 talents, the Canadian eventually came through on the strength of a late break, edging past the Greek for the fifth time in seven career head-to-head meetings, 6-2, 3-6, 6-4.

In a spirited battle between two electric shotmakers with one-handed backhands, it was Shapovalov who found an extra gear in a tense third set, scoring the break in the final game to book a second-round clash with Argentina’s Tomas Martin Etcheverry, the No. 29 seed.

“Definitely never easy to draw a guy like Stefanos first round,” Shapovalov said. “I think for both of us, it was a very tough matchup, and I knew I had to come out here and play my A game. It's never easy to do that in the first rounds, but luckily, I was able to do that today, so, yeah, definitely very happy with the win.”

Shapovalov told the crowd that he was happy to get back on Stadium 1 after losing to Carlos Alcaraz in straight sets on the big stage last year.

“He destroyed me,” the World No. 39 said.

Shapovalov, who improves to 5-4 on the season, says he’s trying to conserve his energy for bigger tournaments like this one. So far, so good.

“I'm definitely trying to play less, conserve the body and just really try to focus on the big tournaments. I’m definitely very excited to get the win today and excited for the next match.”
