Top seed and former runner-up Marion Bartoli of France was one of four upset victims Tuesday at the $235,000 Strasbourg International tennis event, a final clay-court French Open tune-up.

Italy's Camila Giorgi upended the former Wimbledon runner-up and 2011 Strasbourg finalist Bartoli in 6-3, 6-2 fashion at Strasbourg Tennis Club, where rain wiped out Monday's schedule.

Other upsets occurred when French wild card Virginie Razzano toppled second- seeded Austrian Tamira Paszek 6-1, 6-4, American Lauren Davis knocked out sixth-seeded compatriot Christina McHale 7-5, 6-3, and Spaniard Maria-Teresa Torro-Flor erased eighth-seeded Slovakian veteran Daniela Hantuchova 6-3, 4-6, 7-6 (7-4).

Four other seeded women avoided the upset bug, as No. 3 Alize Cornet whipped fellow Frenchwoman Mathilde Johansson, 6-3, 6-2; No. 4 Su-Wei Hsieh of Taiwan overcame German Annika Beck 6-7 (6-8), 7-5, 6-1; No. 5 Monica Niculescu of Romania fought back to best New Zealand's Marina Erakovic 6-7 (7-9), 6-3, 7-6 (7-5); and No. 7 Chanelle Scheepers of South Africa handled French wild card Claire Feuerstein 7-5, 6-4.

Several other women posted first-round wins, including Italian qualifier Flavia Pennetta, Czech Lucie Hradecka and Swede Johanna Larsson. Hradecka was a finalist here back in 2009.

The second round will be staged on Wednesday, including a match for the crowd favorite Cornet, who will be opposed by Polish qualifier Magda Linette.

Cornet lost to Italian Francesca Schiavone in last year's Strasbourg finale.

The 2013 Strasbourg champion will collect $41,000.
