Olympic champion Chad le Clos fought back hard on the final lap to snatch victory from Japan’s Daiya Seto in the 200m butterfly in Barcelona on Wednesday evening. After missing the podium in this event in the opening leg of the Mare Nostrum series in Canet at the weekend‚ the South African star bounced back with his trademark strong finish to clock the second-fastest time of the year so far.He touched in 1min 54.90sec to finish 21-hundredths of a second in front of Seto‚ who boasts the quickest time of 2015 to date‚ a 1:54.46.Seto‚ also the fastest in the world for 2014‚ and the ever-competitive Le Clos are gearing up for a titanic battle at the world championships in Kazan‚ Russia‚ in early August.But SA’s other Olympic swimming champion‚ Cameron van der Burgh‚ had to settle for third spot in the 100m breaststroke.He took an early lead‚ but by the time he got to the turn he was behind new world record-holder Adam Peaty and Japan’s Yasuhiro Koseki‚ the Pan Pacific champion.Commonwealth Games champion Peaty touched first in 59.55 ahead of Koseki‚ in an outside lane‚ in 59.81.
