(CNN) -- A week can be a long time when you're one of the planet's best young skiers. 

On Wednesday, Mikaela Shiffrin turned 18. On Saturday she added the World Cup slalom crown to last month's world championships title, and on Tuesday she'll be back from Europe to appear on U.S. national television. 

"Hopefully I don't trip when I'm going on stage. If you knew me for longer than a day you would know that I spill things and I break things and I trip a lot. You would not think I'd be good at slalom." 

But she's so good that she denied the world's best female skier this season yet another accolade at the finale in Lenzerheide, Switzerland. 

Tina Maze had been poised to add the slalom title to her overall, giant slalom and super-G Crystal Globes, having been denied the downhill when fog canceled racing on Shiffrin's birthday. 

The Slovenian was the fastest on the opening run, and led the standings by seven points, but Shiffrin made up a 1.17-second deficit to claim her fourth World Cup race this season and become the fourth youngest woman to win the title. 

She is only the third non-European to win the slalom globe, following compatriot Tamara McKinney in 1984 and Canadian Betsy Clifford in 1971. No other non-European woman has won four World Cup races in a season. 

"I was freaking out, this time there was really too much emotion," said Shiffrin, who last month in Austria was the youngest winner of the slalom title at a world championships since 1974.
