MONTALTO DI CASTRO, Italy (AP) World track champion Fernando Gaviria sprinted to his first World Tour victory on Friday, winning the third stage of the Tirreno-Adriatico.
The Colombian, who claimed a second successive victory in the omnium at the track cycling world championships on Sunday, edged out fellow youngster Caleb Ewan in a bunch sprint.
Elia Viviani was third, just ahead of world champion Peter Sagan, at the end of the 176-kilometer (110-mile) ride from Castelnuovo Val di Cecina to Montalto di Castro.
''I'm completely happy,'' said the 21-year-old Gaviria, who signed his first World Tour contract in August. ''I want to thank my team, without them I couldn't have had this victory. It's hugely satisfying of course. I have some amazing teammates.''
It was a second straight win at the Tirreno-Adriatico for Etixx-Quick-Step after Zdenek Stybar's victory on Thursday.
Stybar remains top of the overall standings, nine seconds ahead of Damiano Caruso and Daniel Oss, who took the leader's blue jersey after BMC Racing won the opening team trial stage on Wednesday.
There was a breakaway of four riders who led for most of the day before being caught with just 1.5km (0.9 miles) remaining and Gaviria accelerated as the road pitched upwards.
The seven-day Tirreno-Adriatico continues on Saturday with the longest stage of the race, a 216km (134-mile) ride from Montalto di Castro to Foligno.
