Aryna Sabalenka received "hate" in the dressing room after Russia's invasion of Ukraine.
Sabalenka finished as runner-up at Indian Wells last week, losing to Elena Rybakina, who she defeated in the Australian Open final in January.
Born in Belarus, an ally of Russia, the 24-year-old revealed ahead of her Miami Open campaign that "weird conversations" had come from members of other players' teams, rather than her fellow pros.
"It was really tough for me because I've never faced that much hate in the locker room," she said. "There are a lot of haters on Instagram when you're losing matches, but in the locker room I've never faced that.
"I had some, not like fights, but I had some weird conversations with, not the girls, but with members of their team. It was tough. It was a tough period. But now it's getting better.
"It was really tough to understand that there's so many people who hate me for no reason. I did nothing."
24 - Since 2018, when Aryna Sabalenka won her first match against a top-10 (Karolina Pliskova in Eastbourne), she is the player with the most top-10 wins: 24, surpassing Maria Sakkari (23).

Players from Russia and Belarus have been classed as neutral since the invasion, and were banned from last year's Wimbledon.
Ukraine's Lesia Tsurenko pulled out of her match against Sabalenka at Indian Wells after suffering a panic attack following a conversation she had with WTA chief executive Steve Simon about tennis's response to the invasion.
World number one Iga Swiatek had called for greater support for Ukrainian players as a result of the conflict but another Belarusian, Victoria Azarenka, disagreed.
"There are certain players that have different feelings and behaviours. Overall, I don't necessarily share the same opinion as Iga does," Azarenka said.
"I'd encourage her to look at the things that have been done before she makes comments. As a player council member I'm happy to provide the facts. That would be a more appropriate way to have that conversation."
