Jungels, who wore the pink jersey earlier in the 100th edition of the race, finished the 199 km ride from Valdengo to Bergamo just ahead of Colombia’s race favourite Nairo Quintana after finding himself in the rare position of a bunch sprint.
With a host of fellow all-rounders and climbers for company, the Quick Step all-rounder took his chance 100 metres before the finish to claim his maiden win on the three-week Italian race.
“This is my first sprint victory. To do it at the Giro in front of these guys is wonderful. It’s not easy to realise but I’m super happy with this victory,” said Jungels, who finished sixth overall on his debut last year.
“I knew I had good legs today as I felt good in the climbs. I tried my luck in the final climb but it was a bit longer than I expected.
“In the downhill I was in a perfect position, on the wheel of (Domenico) Pozzovivo for sprinting.”
Sunweb team leader Dumoulin and the chasing peloton crossed the line six seconds later to allow the Dutchman to maintain an overall lead of 2min 41sec on rival Quintana before the race’s third and final rest day today.
Dumoulin has been in the race lead since crushing the field to win the 10th stage time trial last Tuesday in Montefalcone, a win that pushed Quintana into second overall at nearly three minutes behind.
