Dutch rider Taco van der Hoorn claimed a surprise breakaway win on stage three of the Giro d"Italia, a 190-km ride from Biella to Canale, on Monday as Italy"s Filippo Ganna retained the overall lead. Van der Hoorn, riding for the Belgian team Intermarche-Wanty-Gobert Materiaux, attacked out of a dwindling and seemingly doomed breakaway group with just under nine km to go and held off the chasing peloton to win by four seconds. Davide Cimolai, of Israel Start-Up Nation, sprinted to second place ahead of former three-time world champion Peter Sagan of Bora-hansgrohe in third. Ineos Grenadiers rider Ganna holds onto the overall leader"s pink jersey for a third day after completing a rain-soaked stage safely in the peloton. Norway"s Tobias Foss climbed into second place in the general classification, 16 seconds down on Ganna, after leapfrogging fellow Team Jumbo-Visma rider Edoardo Affini, who lost time and dropped down the rankings. Deceuninck-Quick-Step"s Remco Evenepoel moved into third place, 20 seconds down on Ganna. Ganna, the world time-trial champion, is expected to relinquish the overall lead in Tuesday"s fourth stage to Sestola, which ends with a steep, 4.3km climb and a 2.5km dash to the finish.
