It was a pity that not many turned up to watch the cream of world table tennis in action but those who did, enjoyed to the hilt.
The men's final was a repeat of the 2014 Asian Games title clash with little separating the class of world no. 2 Xu and Fan Zhendong, a place below his Chinese teammate in the latest ITTF rankings.
The 18-year-old sensation Fan led 3-1 and was on course for a maiden title before Xu rallied back for an 11-8 11-13 11-13 5-11 11-8 11-4 11-7 victory.
The momentum shifted back to Xu after he won the fifth with a lucky net cord. From there on he kept control on the proceedings to scrape through. It was a sheer treat to watch left-handed Xu unleash expansive forehand drives with his rare penhold grip and more often than not, those powerful strokes were irretrievable.
