Former U.S. Open champion Emma Raducanu barely broke a sweat as she brushed aside Japanese wild card Sayaka Ishii 6-2 6-1 on Wednesday to reach the second round of the Miami Open.

Raducanu, who was ousted in the first round at Indian Wells, regained her footing against Ishii as she won 77% of her first-serve points, fired down six aces and converted five of her six break point chances in the 65-minute match.

Up next for Britain’s Raducanu will be American world No. 10 Emma Navarro, who won a WTA 500 event in Mexico in early March for her second career title before losing in the third round at Indian Wells.

“It’s going to be an extremely challenging match,” Raducanu said during her on-court interview. “She’s probably in better form, so I can go out and express myself and try and compete for every point.”
