Shiffrin led after Sunday's first run by 1.47 seconds, a huge margin in slalom, and that is becoming her tactical approach: Ski as aggressively as possible on the first run on a relatively clean course to build the biggest lead possible, then be judicious about where to push and where to be careful on the second run when the course is bound to be chewed up for the first-run leaders because they are the last to race in the second run. The American is the first female skier with three straight wins at the start of a year since Vreni Schneider of Switzerland achieved the feat in 1989.
Only Annemarie Moser-Proell (41) won more World Cup races before turning 23 - and Shiffrin, with her birthday in March, has plenty of opportunities to better that. "To be honest, I am not really counting". "For sure I want to win, but everybody wants to win. The surface is incredible and froze overnight so it's just so much fun to ski".

"She's skiing super fast", runner-up Frida Hansdotter of Sweden said Sunday in the post-race news conference.

"I let it go down the hill and I am really, really happy with my skiing that run", said Shiffrin, who also triumphed in Saturday's giant slalom on the same course. "We need to train harder and ski faster".
"A lot of the girls have been sick so I didn't feel like it was an excuse for today".
Shiffrin is also just two wins from her total for last season of 11 victories, when she captured her first overall World Cup title, and just three from tying Vonn's single-season American record of 12 victories.More news: Vodafone Group (VOD) Raised to "Buy" at BidaskClub
