Cirstea lost her opener at Roland Garros, Birmingham and Eastbourne before upsetting Li Na en route to a third round showing at Wimbledon. In Stanford, she went all the way to the semifinals before losing her opener at the Olympics and Montréal, where she suffered a double bagel defeat at the hands of Sesil Karatantcheva. Last week in Cincinnati, she had a respectable outing that included taking eventual champ Li to three sets in the second round.
"I love this place and have really good memories from last year," the eighth-seeded Cirstea said. "It's good to be back as a seed this year with a few more wins coming in. It has been going well."
Cirstea's encounter with Gajdosova was a tight one, as she lost three straight games after racing out to a 4-1 first set lead, prevailed in a tie-break and rallied after going down an early break in the second for a 76(2) 64 triumph.
"I'm happy to pull off the match today," said Cirstea, who is now 3-0 against Gajdosova. "I played her last year in the first round here, this year again. Every single time I play her, it's quite tough, so I'm just happy to win this one.
"I was hoping it'd be a little hotter this year. I remember last year here it was very, very hot. I'm one of those players who loves to play in the heat. Put me at 2 o'clock and I have no problems. But this year it's actually not bad. Playing the night session, it was actually quite cool out there."
Other seeded winners were No.4 seed Yanina Wickmayer and No.7 seed Chanelle Scheepers. Wickmayer was a 63 64 victor over Heather Watson, while Scheepers recorded a 60 62 rout of Barbora Zahlavova Strycova - her first win in three meetings with the Czech.
One seed did go down, though it was hardly a surprise, as Aleksandra Wozniak is full of confidence after becoming the first Canadian in 20 years to make the Rogers Cup quarterfinals at her last event. On top of that, she is playing her first tournament as a Top 50 player in more than two years. She beat fifth-seeded Klara Zakopalova, 60 76(2), in a match featuring a 20-minute first set but a 58-minute second set.
Among those in action Monday is top-seeded Angelique Kerber, fresh off a run to the final in Cincinnati and an ascension to a career-high ranking of No.6.
