OFTERSCHWANG, Germany, March 10 (Reuters) - Tina Maze won her duel with world champion Mikaela Shiffrin in a women's World Cup slalom on Sunday to keep her chances alive of scoring a grand slam of crystal globes this season.
Led by her young American rival in the morning run, the Slovenian overall runaway leader fought back in the afternoon to snatch her 10th victory of the World Cup season, her second in a slalom.
In a combined time of one minute and 52.85 seconds, Maze beat Swiss hopeful Wendy Holdener by 0.25 seconds while Shiffrin settled for third, 0.75 adrift.
With 2,254 points, the utterly dominant Maze again increased the all-time points record in the overall World Cup and totals more than twice the score of nearest rival Maria Hoefl-Riesch of Germany, who is on 1,065 points.
The Slovenian, who beat Hermann Maier's previous record total of 2,000 points last weekend, also improved on one of the Austrian's other career statistics by earning her 22nd podium of the season.
In the slalom World Cup standings, she now leads second-placed Shiffrin by seven points with only one race left at the Lenzerheide finals next week.
Maze remains in contention to win all four discipline World Cups on top of the overall big globe. (Editing by Mark Meadows; email@example.com; +44 20 7542 7933; Reuters Messaging:; firstname.lastname@example.org)
