Marta Kostyuk shook the chair umpire's hand but immediately walked straight to her chair without acknowledging Aryna SabalenkaDates: 28 May-11 June Venue: Roland Garros, ParisCoverage: Live text and radio commentaries of selected matches across BBC Radio 5 Sports Extra, the BBC Sport website and appUkraine's Marta Kostyuk was booed off court for avoiding a handshake with Aryna Sabalenka after the Belarusian's first-round win at the French Open.
Second seed Sabalenka delivered a dominant performance to win 6-3 6-2.
Belarus is an ally of Russia and allowed troops to use its territory to launch last year's invasion of Ukraine.
"I thought the boos were against me so I felt a bit surprised," said Australian Open champion Sabalenka. "But then I felt your support."
The pair did not have the traditional pre-match photo following the coin toss. After Sabalenka sealed victory, Kostyuk walked straight to shake the umpire's hand and then to her chair, prompting boos from the crowd on Court Philippe-Chatrier.
Sabalenka was startled by the initial booing, thinking it was directed at her, before realising it was aimed at world number 28 Kostyuk when the crowd again booed as the Ukrainian left the court.
"It was a very tough match, tough emotionally," said Sabalenka in her on-court interview.
Prior to the match, Sabalenka - who has previously said "no-one supports war" - had said she understood if Kostyuk "hates" her.
Kostyuk, 20, refused to shake hands with Belarus' Victoria Azarenka at last year's US Open.
