Fourth seed Marion Bartoli began her final warm-up to the U.S. Open in impressive style by blasting Australian qualifier Anastasia Rodionova 6-1 6-4 in first round action at the New Haven Open on Monday.

The 26-year-old Frenchwoman, one of four top 10 players taking part in the U.S. Open tune-up, was forced to save three break points in the opening but was never threatened in setting up a second round meeting with Czech Klara Zakopalova.

Fifth seed Agnieszka Radwanska of Poland cruised into the second round by pounding Russia's Ekaterina Makarova 6-1 6-2 while eighth seed Anastasia Pavlyuchenkova came out on top of an all-Russian clash rallying past Vera Dushevina 3-6 6-4 6-3.
