The inaugural edition of the Transylvania Open features a packed field led by home favorite Simona Halep and US Open champion Emma Raducanu. But the Romanian government's latest COVID-19 regulations have resulted in the 2021 edition of the WTA 250 event being played without spectators.Raducanu had earlier expressed her excitement at making her tour debut in Romania, the country where her father was born. And fans jumped at the opportunity to watch the fast-rising teenager during Sunday's practice. Spectators thronged the Center Court for the evening session, which featured Emma Raducanu and Elena-Garbiela Ruse's second hit.Tournament officials have since shared videos from the evening, which show excited crowds cheering for the players. One of them, a 30-second long clip, even sees fans attempting a Mexican wave from the stands behind the players.Transylvania Open@TransylvaniaOpnMexican waves at Emma x Gabi Ruse second practice session 😅#TO20217:14 AM · Oct 24, 20215410Mexican waves at Emma x Gabi Ruse second practice session 😅#TO2021 https://t.co/P35RyljRe5The organizers also held an interaction session for fans featuring Raducanu and Ruse, as well as other Romanian players - including Monica Niculescu and Ana Bogdan.Emma Raducanu can be heard speaking in Romanian, to a rousing reaction from the packed crowd.Transylvania Open@TransylvaniaOpnEmma speaks in Romanian on Center Court, people going crazy for her.
