Swimmer Srihari Nataraj clocked a personal best of 54.07 seconds to win gold in the men's 100 metres backstroke in the Uzbekistan Open Summer Swimming Championships in Tashkent on Thursday. However, his performance was slower than the Olympic 'A' qualification time of 53.85 seconds.

Earlier, in the preliminary round of the men's 100m, the 19-year-old Nataraj had clocked 54.10 seconds. Though he bettered his performance in the final, it wasn't good enough for the Olympic 'A' qualification mark.
