Wozniacki eases through in New Haven
Third seed Caroline Wozniacki eased into the second round of the New Haven Open with a regulation 6-3 6-3 win over Ekaterina Makarova.
The Danish former world number one was far from comfortable on her own serve in Yale, but with Makarova struggling even more, she did enough to secure a date with Sofia Arvidsson.
Swede Arvidsson beat home hope Melanie Oudin 6-4 6-1 to book her place in the next round.
Fourth seed Sara Errani won through with a 6-4 7-5 victory over another American Bethanie Mattek-Sands, while numbers six and seven seeds Dominika Cibulkova and Maria Kirilenko also progressed in straight sets.
Cibulkova saw off Anabel Medina Garrigues 7-5 6-3 while Kirilenko eased past Shahar Peer 6-2 6-2.
Up and coming Mona Barthel continued her progression with a 6-3 7-5 win over Daniela Hantuchova, Andrea Petkovic downed Timea Babos and Nicole Gibbs won an all-American clash with Alexa Glatch 6-4 1-6 6-4.
Olga Govortsova of Belarus beat Vera Dushevina 6-7(5) 6-4 6-2; her prize is a second-round clash with top seed Agnieszka Radwanska.
