Top-seeded Qinwen Zheng claimed the Toray Pan Pacific Open with a 7-6 (5) 6-3 win over American wild card Sofia Kenin to clinch her place in the WTA finals next month.
Zheng, who won gold at the Paris Olympics, fired 16 aces and only faced a single break point throughout the one hour and 52 minute victory as the world No 7 claimed her third trophy this season.
In the first set, Zheng was unable to convert five breakpoints in a tight encounter against Kenin but managed to win the tiebreak with a brilliant forehand winner.
Zheng was much more dominant in the second set breaking for 2-0 when Kenin netted a backhand, before consolidating that break to go 3-0 up.
Kenin continued to push, forcing the gold medallist to defend her first breakpoint of the match but eventually the Zheng claimed victory in the second set too.
Despite the result, Kenin, 25, put on her best performance of the season. The American was ranked as high as No 4 early in 2020, but a series of injuries, including ankle and quadricep ailments, has seen her WTA ranking drop to its current 155.
