Ecuador's Jhonatan Narvaez gave the Ineos team their third stage win in this year's Giro d'Italia, crossing the line alone on a wet stage 12 at Cesenatico on Thursday.
"It is not a problem for me to race in the rain, in fact, I prefer it to the hot weather."
Portugal's Joao Almeida retained the overall race leader's pink jersey in the stage around the home region of Italian cycling great Marco Pantani, who died in 2004.
Narvaez joined Ineos last year and was competing in his second Giro, which compatriot Richard Carapaz won last year.
Friday's 13th stage covers 192km from Cervia to Monselice, overly mostly flat terrain before two short, steep climbs near the finish line.
12. Wilco Kelderman (NED/SUN) 8:25, 16. Domenico Pozzovivo (ITA/NTT) s.t., 17. Vincenzo Nibali (ITA/TRE) s.t., 20. Jakob Fuglsang (DEN/AST) s.t.
