Calderano ended victorious in the men's tournament after staging a dramatic comeback win against England's Liam Pitchford.

The 6-11, 1-11, 11-8, 11-0, 11-4, 10-12, 11-7 result saw Calderano claim his third WTT Series title of the year.

Pitchford looked formidable in the early stages and appeared to be strolling to glory as he flew into a two-game lead.

However, Calderano found himself 2-0 down on multiple occasions in the Omani capital against the likes of Frenchmen Jules Rolland and Simon Gauzy in the round-of-16 and semi-finals, respectively.

The momentum switched massively in the third game as he went on to win 22 of the next 26 points.

Pitchford then saved match point at 10-9 in game six before winning it and taking the final to a decider.

However, he got off to a poor start going down 7-2 before Calderano pushed on for the title.

In the women's final, Hayata secured her fourth WTT Series singles trophy following a dominant display.

Pan American Games champion Adriana Díaz of Puerto Rico stood in her way but was swept aside in under 30 minutes.

It was one-way traffic from start to finish, despite the two being separated by just one seeding position, as Hayata crushed her opponent 11-7, 11-5, 11-5, 11-6.

Hong Kong duo Ng Wing Lam and Zhu Chengzhu cruised to the women's doubles title in Muscat as they beat Turkey's Sibel Altinkaya and Serbian Andrea Todorovic 11-5, 11-6, 11-4 in the opening match of the finals day.

Germans Patrick Franziska and Dimitrij Ovtcharov also took a straight-games win, this time in the men's doubles final where they beat Anton Kallberg and Kristian Karlsson of Sweden 13-11, 11-4, 11-9.

The mixed doubles gold then went to Chinese Taipei's Lin Yun-Ju and Chen Szu-Yu following an 11-7, 16-18, 11-8, 11-3 result against Miwa Harimoto and Sora Matsushima of Japan.
