TOKYO (AP) — Caroline Wozniacki overpowered Japanese teenager Naomi Osaka 7–5, 6–3 to win the Pan Pacific Open on Sunday.
Wozniacki, who also won here in 2010, took control in the second set when she broke in the second game.
The former No. 1 led 5–0 before Osaka fought back to give home fans some hope, but Wozniacki sealed victory in the ninth game when Osaka's return went wide.
Osaka, playing in her first WTA final, had led 3–1 in the first set but couldn't sustain the momentum.
Wozniacki, who has faced ankle and wrist injuries this season, took a medical timeout in the first set and came back with a bandaged left leg. She broke Osaka after returning and won three of the last four games of the set.
