The USA's David Colturi is in the lead after the first day of dives at Texas' Possum Kingdom Lake on Friday.
The men's Seeding Round - the first of four rounds in total - took place on a sweltering Friday afternoon in the Deep South, as the world's best high divers went all the way up to 28 metres and a platform positioned on 'Hell's Gate'.
The gathered spectators witnessed a slice of diving heaven, however, as Chicago-based Colturi hit a perfect inward double half that saw head judge Claudio De Miro reaching for a 10 and the 25-year-old accumulating a total of 106.40 points. Colturi will now face off against the winner of the World Series' stop in Cuba, Blake Aldridge, in Rounds 1 and 2 of the head-to-head for a place in Saturday's final.
It was a great day for the US women as well, with Cesilie Carlton heading a trio of American athletes after the first two rounds of the first Women's World Series event.
Carlton, one of seven female athletes competing from 20 metres, had a programme which included one required dive, a double half, with a fixed Degree of Difficulty of 2.6, and one optional dive, a double one and a half, with five international judges, including legendary Olympian Greg Louganis, awarding the scores.
The women's event concludes on Saturday with a third and final round, and a trio of Americans, Carlton, Rachelle Simpson and wildcard Tara Hyer-Tira, are all in contention for top spot.
