Germany's Doll powered to victory in the men's 15km mass start over Johannes Thingnes Boe.
The 31-year-old claimed the third World Cup win of his career after registering only one penalty to come home in a time of 37:14.9.
Boe finished 31.3 seconds behind him to earn silver after carrying three penalties, but it was enough to ensure two Norwegians on the podium as compatriot Sturla Holm Laegreid claimed bronze, as he finished just under a minute behind Boe.
"I am really proud of my standing shooting and my last lap; that I could stay in front of Johannes Thingnes Boe," Doll said after his first mass start win.
"Everybody knows he is a really fast skier. I was a little bit nervous when I left the shooting range -- I knew I had to push really hard in the first half of the lap and see if he would come closer or if he would lose maybe some seconds.
"The first half of the lap was really hard and then when I went to this long uphill to the Huberalm I saw he was not in reach, so I had some seconds to enjoy this moment."
Doll is now 11th in the overall World Cup standings with Boe two places ahead of Laegreid in fifth, as France's Quentin Fillon Maillet remains top with 636 points after an eighth-placed finish.
