Rio de janeiro:Michael Phelps won two gold medals, avenging his 200 metres butterfly defeat from the London Olympics and then anchoring the US 4x200 freestyle team to victory on a night of high drama and emotion in the pool.
Katie Ledecky of the United States won her second gold medal of the meeting and Hungary's Katinka Hosszu her third, extending their dominance of women's swimming in feats that on any other day would have grabbed top billing.
By his own admission, Michael Phelps could not have scripted it better as he won back the title closest to his heart on an evening of pure gold for the most medalled Olympic athlete of all time.
The 200 metres butterfly was the first race he swam at an Olympics, at Sydney in 2000, and the gold that got away -- the one he wanted back after being beaten by a fingertip at the 2012 London Games by South African Chad Le Clos. (UNI)
