Weirather gives mum perfect birthday present with Super-G win
Lieschtenstein's Tina Weirather celebrates after winning the FIS Alpine World Cup Women's Super-G on December 14, 2013 in St Moritz
With a time of 1min 17.38sec, the 24-year-old finished ahead of Kajsa Kling of Sweden by a margin of 0.31 seconds, with Austria's Anna Fenninger taking third spot, 0.39 seconds off the pace.
It was Weirather's second World Cup win of what has been an excellent start to the season. In eight races, she has finished on the podium on five occasions.
Weirather is the daughter of former Austrian ski star Harti Weirather and Liechtenstein's two-time Olympic and two-time world champion Hanni Wenzel, who was celebrating her 57th birthday on Saturday.
"I had already bought her a present but this first place is the most beautiful gift of all," said Weirather.
This victory sees her move to within 37 points of Switzerland's Lara Gut in the overall World Cup standings.
Home favourite Gut won the first two Super-G races but only came in seventh on Saturday on a course where she recorded her very first World Cup win four years ago.
Kling followed up an impressive showing at Lake Louise in the Canadian Rockies last week with a run to second, while Fenninger's third place means she has finished on the podium in every Super-G race this season.
