Lindsey Vonn's concussion may turn out to have been a blessing in disguise.

Having skipped the second half of last month's world championships to recover, the Olympic downhill champion now appears in top form for the tense finale of the World Cup circuit.

Vonn clinched her third discipline title in three days with a super-G victory Sunday in Tarvisio, Italy, to wrap up a memorable weekend of racing.

Vonn took the super-combined and downhill titles the past two days and has moved within 96 points of German rival and good friend Maria Riesch in the overall standings with six races remaining this season.

  • Mario Matt of Austria won his second straight World Cup slalom race in Kranjska Gora, Slovenia, and Nolan Kasper of the U.S. had the fastest second run to finish in a tie for second, a career-best showing. Matt was fifth after the opening run and finished the Podkoren course in a combined time of 1 minute, 49.19 seconds.
