MELBOURNE: Maria Sakkari took umbrage with opponent Diana Shnaider’s vocal celebrations after winning points at the Australian Open on Wednesday but silenced the teenage qualifier with a finger-wagging rant on the way to a comeback 3-6 7-5 6-3 win. World number 106 Shnaider, wearing a black and white polka dot kerchief, made a habit of roaring in Sakkari’s direction and throwing her icy stares, and it got too much for the Greek sixth seed at 5-5 in the second set at Margaret Court Arena. After a wry grin, Sakkari grew serious and walked toward the chair umpire holding up a finger, saying: “If she screams one more time in my face … No, no, no, no. “One more time … She’s coming towards me. One more time and I’m going to speak to the referee.” Taking charge of the situation appeared to work for Sakkari, who duly broke the 18-year-old Russian to take the set, then locked down the match to reach the third round.
