Tessa Worley missed out on the chance to wrap up her maiden crystal globe as Mikaela Shiffrin claimed giant slalom glory in the penultimate round of the season in Squaw Valley on Friday.
World champion Worley headed to California with a 120-point cushion over overall leader Shiffrin in the giant slalom standings but will have to finish the job in Aspen next week after only managing third place.
American Shiffrin outpaced Worley by two tenths of a second on the first run, before stretching that advantage to 0.86 seconds on her second.
Italy's Federica Brignone produced the second fastest run of the day - one minute, 6.75 seconds - to launch herself to within 0.07 seconds of Shiffrin on her second run, splitting the title rivals in a performance that could have a big say in who takes home the globe.
Victory for Shiffrin pulls her level with Lindsey Vonn on four World Cup giant slalom wins - only Tamara McKinney (9) has won more.
Shiffrin is now 278 points clear of Ilka Stuhec at the top of the overall standings as she closes in on a maiden title.
