Maria Sakkari, the No. 8 seed in women’s singles at the 2023 U.S. Open, said she smelled marijuana during her first-round upset loss to Rebeka Masarova on Monday night.

"It was weed," Sakkari said after the match, per ESPN.

Sakkari fell in straight sets, 6-4, 6-4, but it was a match that she appeared to be in full control of from the beginning. She was leading 4-1 on Court 17 against Masarova, but Sakkari said she smelled it from the beginning.

The Grecian said she mentioned the marijuana smell to the chair umpire during a changeover in the match. 

"I think it’s from the park," Sakkari told the umpire.

However, despite smelling marijuana during the match, Sakkari did not make any excuses about her play. 

"You don’t really think about it because all you care is just to win the match," Sakkari said. "I smelled it, but that was it. Like, it wasn’t something that I paid attention to."

She continued, "Sometimes you smell food, sometimes you smell cigarettes, sometimes you smell weed. I mean, it's something we cannot control because we're in an open space. There's a park behind. People can do whatever they want."

While it may not have bothered Sakkari, players like Nick Kyrgios have also complained in the past for medical reasons.

During a match last year, Kyrgios mentioned smelling marijuana, and since he is asthmatic, he did not believe inhaling it was good for him, especially on the court. 

Sakkari went through her third straight first-round exit in a Grand Slam tournament.
