The final kilometre served up a 4% incline to the finish in Manosque, Pedersen looking in no huge hurry on the right side of the road with Mohorič glued to his wheel.
The gamble by Mohorič did not work, as Pedersen jumped with 300 metres to go and he easily crossed the line for his first victory of the season, three seconds ahead of his breakaway companion.
Fred Wright (Bahrain Victorious) used a strong kick on the final stretch to grab third, just ahead of Dorian Godon (Decathlon AG2R La Mondiale) in the reduced peloton which crossed the line in Manosque 16 seconds back.
