Jelena Ostapenko gives serious sideye to electronic line calling after Australian Open win

WATCH: Ostapenko ultimately kept her margins big enough to earn a clean win over Gauff on Saturday.

It sometimes seemed as if Jelena Ostapenko was up against more than one opponent when she took on Coco Gauff in the fourth round of the Australian Open.

The American teenager should have proven a sufficient challenge and yet the famously expressive and effortlessly fashionable former Roland Garros champion couldn’t help but feel hard done by the electronic line calls that overruled what she felt were surefire winners.

Ostapenko ultimately gave a vote of no confidence to former player Laura Robson during her on-court interview.

“In the system?” she asked when pressed on whether she had faith in every call. “To be honest, no!”

Even umpire James Keothavong couldn’t help but laugh as the conspiratorial 25-year-old outlined her logic in the moment, which often involves help from her team.

“Honestly, this live electronic system, I don’t know,” she said after defeating Gauff in straight sets, 7-5, 6-3. “Sometimes it feels like it makes some mistakes. Of course, we have to play. Sometimes I look at my team because I know I’m wrong, but I feel like some balls are pretty close, so I want to know what they think about the call.”

When you hit as many winners as Ostapenko—30 against Gauff alone on Saturday—it’s hard not to go on feeling over fact.

“Sometimes it’s one centimeter out, which is like ‘Wow,’ but in the deciding moments, I think it went in and that’s the most important.”

Ostapenko took the exchange in stride as she headed into her first Grand Slam quarterfinal since 2018; awaiting her there is reigning Wimbledon champion Elena Rybakina, who ousted world No. 1 Iga Swiatek in straight sets.
