Jiaqi, at 2582 USATT rating, came in as the top rated "final 4" player (even though the announcer wrongly said Liu Xibo to be the top seed). But she did not quite do very well until the last match of the tournament, when she hung in there to beat Liu Xibo after Xibo led 3 games to 1 with a 5-point lead in the 5th game. But that was too little too late as the tournament rankings were already determined before even that match started.
Jiaqi, champion a couple of years ago, finished at #4 at the Open event.
