Alpine skiing: a 50th victory in slalom for Shiffrin, of the United States

SEMMERING, Austria — American Mikaela Shiffrin beat compatriot Paula Moltzan for an American double in a night slalom on Thursday, becoming the first skier with 50 World Cup victories in a single discipline.

No other skier, female or male, has won an event more than 46 times in the 56-year history of the World Cup.

The result also marked Shiffrin’s 80th World Cup victory overall – two shy of Lindsey Vonn’s women’s record.

Building on a big lead of more than seven tenths of a second in the first run, Shiffrin overcame several errors in his final run to finish 0.29 seconds ahead of Moltzan, who clinched his first career podium in the discipline.

It was the first time since 1971 that the United States had done a double in a women’s World Cup slalom.

“Paula had a great run, I saw it straight away. I thought she might win. It’s so special to share a podium with her,” said Shiffrin.

Germany’s Lena Dürr finished third by 34 hundredths, followed by Shiffrin’s biggest slalom rivals, Petra Vlhová and Wendy Holdener – the only other runners within a second of the winning time.

Shiffrin can match Vonn next week, when two slaloms are scheduled in Zagreb, Croatia.

Only the great Swede Ingemar Stenmark has won more races than Vonn and Shiffrin, with 86.

Shiffrin has won six races this season, including the last four including last week’s super-G in St. Moritz and two giant slaloms in the past two days.

Canadians Amelia Smart and Ali Nullmeyer finished 15th and 16th, respectively.
