"You know she's lying": Tomljanovic gets into heated argument with Ostapenko over medical timeout 

Ajla Tomljanovic captured a monumental 4-6, 6-4, 6-2 win over Jelena Ostapenko to make her second major Round of 16. Following her triumph, however, viewers were talking more about the heated argument that took place between the two rivals on Court 15 than the result itself.

Tomljanovic accused the Latvian of faking an injury and exercising gamesmanship in attempt to hinder her game.

Twice breaking Ostapenko's serve to take a 4-0 lead in the deciding set, Ostapenko unexpectedly requested a medial timeout, stating she pulled an abdominal muscle. The Aussie quickly approached chair umpire Fiona Edwards with audible irritation.

"You know she's lying, right? We all know," Tomljanovic told the umpire.

Tomljanovic demanded to see the tournament's supervisor as Ostapenko waited for the trainer to arrive for treatment. The conversation between Tomljanovic and the chair would go on for a few minutes, but the decision to grant Ostapenko's request wasn't overturned.

Since Ostapenko's issue was a developing acute medical condition, an immediate stoppage to treat the injury with a physio is fair game. Tomljanovic's frustration is nonetheless valid: the current MTO rules are vague, leave room for individual interpretation, and are difficult to enforce. Many players over the years have expressed frustration over the easy-to-abuse rules that can lead to strategic plays instead of genuine medical assistance.

When Ostapenko eventually returned to the court from treatment, Tomljanovic finished strong to secure her last 16 spot, but the drama wasn't over as the two hesitated before shaking hands at the net.

"If you think I'm faking it, you can talk with the physio," Ostapenko said, quickly adding "Your behavior is terrible. You have zero respect."

"Honestly, You're one to talk," Tomljanovic responded as the crowd whooped.

Exiting the court, Ostapenko called her "the worst player on tour."

Following the match she told press she had indeed pulled her abdominal muscle in the second set, and was experiencing pain when serving. Ostapenko explained she felt Tomljanovic was "the worst" on tour because of her "very disrespectful" attitude.

Tomljanovic backed her on-court statements, confirming that she believes the 2017 Roland Garros champion was not truly injured, but was instead attempting to disrupt her momentum.

Set to play 18-year-old Brit, Emma Raducanu for a spot in Wimbledon's quarterfinals, it appears what's past is past, and she's looking forward to continuing her excellent grass-court campaign.

"My feelings towards winning exceeds any drama that happened," Tomljanovic said.
