Naomi Osaka battles past Siniakova to reach US Open third round

Naomi Osaka defeated Katerina Siniakova 6-2, 5-7, 6-1 to reach the US Open third round, overcoming a mid-match slump after losing the second set. Osaka, a two-time champion, struggled with tension late in the second set but regrouped to dominate the decider. She previously reached the French Open fourth round and Wimbledon quarter-finals this year, including a win over world No 1 Aryna Sabalenka. Osaka's elaborate outfits, a tribute to Allen Iverson, have drawn criticism, though she says fashion helps her express herself. She faces a tough draw with Elena Rybakina a potential fourth-round opponent.
