Eugenie Bouchard ousted in 1st round at Connecticut Open

Canada's Eugenie Bouchard was upset by Italy's Roberta Vinci 6-1, 6-0 at the Connecticut Open on Monday.

"I didn't expect an easy win," said Vinci, who had to qualify for the tournament. "Eugenie's a great player."

Meanwhile, Agnieszka Radwanska breezed into the second round with a 6-0, 6-2 victory over American CoCo Vandeweghe.

The Krakow, Poland native needed only 65 minutes to set up a second-round meeting with France's Aliza Cornet, who advanced with a three-set win against Yulia Putintseva of Kazakhstan.

"I just started very well," said Radwanska, who wore a Lotto Women's Lux Diamond Dress that resembled a disco ball and sparkled under the Stadium Court lights at night. "Everything was really working for me and I was really focusing on each ball."

Among the other top players to advance were 20-year-old American Madison Keys and sixth-ranked Lucie Safarova from Czechoslovakia. Eighth-ranked Karolina Pliskova, from Czechoslovakia, survived a scare from Slovakia's Polona Hercog before advancing with a 2-6, 7-6 (7-5), 6-2 victory.

Keys battled back from a 0-4 deficit to win the first set 7-6 (7-4) and was leading 4-2 in the second when Svitolina retired due to a lower back injury.

"I'm really happy with how I turned things around today," Keys said. "I kind of just started [hitting] balls on the court, it wasn't rocket science. I stopped missing so many."

Keys, who reached the top 20 after advancing to the Australian Open semifinals earlier this year, is the second-highest ranked American (19th) behind Serena Williams.

Keys vs. Kvitova

Next up for Keys is fourth-ranked Petra Kvitova, who is the top remaining seed at No. 2 after American Simona Halep withdrew Sunday due to injury.

Keys already beat Kvitova once this season, prevailing in straight sets in the round of 32 at the Australian Open.

"Obviously I played really well when I played her in Australia and she was playing well," Keys said.

Safarova had a little easier time beating Russian Daria Gavrilova 6-3, 6-4 in the final afternoon match.

France's Kristina Mladenovic also knocked off eighth-seeded Sara Errani from Italy 6-2, 4-6, 6-4.

Ukraine's Olga Savchuk and France's Caroline Garcia also advanced to the second round.
