Impressive Emma Raducanu into last 16 in Madrid

Emma Raducanu played a near flawless match to dismiss Ukrainian teenager Marta Kostyuk 6-2, 6-1 in Madrid and reach the last-16 of a WTA 1000 tournament for the first time. US Open champion Raducanu, who is playing just the second tour-level clay-court event of her career, committed just five unforced errors and dropped a mere three points behind her first serve en route to a 64-minute victory. "I'm definitely very happy with my performance today.

Marta is a great opponent," said Raducanu of her fellow 19-year-old opponent. "We've played several times in the juniors and then once last year. "I knew it was always going to be a really tough battle so I went out there trying to be really aggressive.

"It's pretty funny because it's my first clay-court season and I'm really enjoying it. Madrid is such a cool city and it's got such a great vibe about it so I definitely want to try and stay here for as long as possible." Raducanu will square off with another Ukrainian in the next round in the form of world number 37 Anhelina Kalinina, who posted the first top-10 victory of her career on Sunday by upsetting home favourite and world number nine Garbine Muguruza 6-3, 6-0 in 81 minutes. Kalinina is making her Madrid debut this week and is contesting just her fourth main draw at the WTA 1000 level.
