Phelps' legend grows as Ledecky, Hosszu win again

Already the most successful Olympian in history by some margin, Phelps triumphed in the men's 200 metre butterfly final to secure the 20th gold of his career.

Michael Phelps and Katie Ledecky further enhanced their illustrious reputations at Rio 2016 on Tuesday, the former claiming two more Olympic gold medals to take his record-breaking tally to 21.

Already the most successful Olympian in history by some margin, Phelps triumphed in the men's 200 metre butterfly final to secure the 20th gold of his career.

Chad Le Clos of South Africa had edged out Phelps in the same event four years ago, but on this occasion the South African finished outside the medals as the fast-finishing Masato Sakai and Tamas Kenderesi claimed silver and bronze. The renewal of battle between Phelps and Le Clos had been much anticipated, yet the latter was ultimately left behind as the two less-heralded names provided the biggest challenge to the victor in a thrilling finish.

Phelps was not finished there, however, and went on to help the United States to a fourth successive victory in the 4x200m freestyle relay, alongside Ryan Lochte, Conor Dwyer and Townley Haas.

Teenage sensation Ledecky held off Sweden's Sarah Sjostrom to add the 200m freestyle crown to her previous success over 400m. The American appears all but certain to end the week with three golds, given her dominance over 800m.

Tuesday's other gold medallist was Katinka Hosszu, who set a new Olympic record in beating Siobhan-Marie O'Connor by three tenths of a second in the women's 200m individual medley final.

Hosszu has now claimed three golds in Rio, all over different distances. Her previous triumphs came in the 100m backstroke and 400m IM.
