Wozniacki joins Madrid upset victims

MADRID, May 11 (UPI) -- World No. 2 Caroline Wozniacki was a straight-set upset victim Tuesday in second-round play of the Madrid Open clay-court tennis tournament.

Wozniacki's 6-2, 6-3 loss to Alona Bondarenko means neither 2009 finalist will be around for the end of this year's event. Wozniacki lost the title match last year to Dinara Safina, who was ousted from the tournament Monday.

Bondarenko piled up five service breaks against Wozniacki and won more points (31-29) on Wozniacki's serve than the world's No. 2 did.

Four other seeded players were also beaten Tuesday. No. 6 Elena Dementieva was stopped 6-1, 3-6, 7-5 by Alexandra Dulgheru; ninth-seeded Agnieszka Radwanska fell 3-6, 6-4, 6-4 to Patty Schnyder; 12th-seeded Marion Bartoli was routed 6-2, 6-0 by Anabel Medina Garrigues; and No. 14-seeded Flavia Pennetta was dropped 7-6 (7-3), 6-3 by Andrea Petkovic.

Seeded second-round winners Tuesday were No. 8 Samantha Stosur, who beat Maria Jose Martinez Sanchez 7-6 (7-2), 6-4; No. 13 Na Li, who got by Dominika Cibulkova 6-2, 3-6, 7-5; and No. 16 Nadia Petrova defeated Anastasia Pavlyuchenkova 6-2, 7-5.

Other winners Tuesday were Lucia Safarova, Aravane Rezai and Shahar Peer.
