Olympic champion Gregorio Paltrinieri of Italy won the men's 1500m freestyle final at the world championships on Sunday to retain the title he won two years ago in Kazan. Paltrinieri clocked 14 minutes, 52.07 seconds with Ukraine's Mykhailo Romanchuk taking silver at 1.29 back and Mack Horton of Australia earning bronze at 11.85 behind.

Romanchuk gave Paltrinieri a hard race, but the Italian held on to add the world title to the Olympic gold he won in Rio de Janeiro. "I did everything I could to beat the Olympic winner, but he is the champion," said the Ukrainian.
