Gleaming white teeth were the only facial feature visible under Emma Raducanu's visor as she celebrated a major win Friday at the Miami Open and reflected on an emotionally strenuous start to her 2025 tennis season.

Emma Raducanu faces a tricky second-round test at the Miami Open against in-form American and namesake, Emma Navarro. The former US Open champion stormed through her opening encounter against 19-year-old Japanese wildcard Sayaka Ishii, a former top junior player ranked 188th in the world.

The British No. 2 had never won a match at the Miami Open before this week, losing in her two previous appearances in 2022 and 2023. But she finally scored a victory over teenage wildcard Sayaka Ishii in the first round on Wednesday, setting up a meeting with Navarro.
