Notes: Insane field with two former No. 1s and an additional Slam champ all unseeded…The Top 3 seeds are current or former No. 1s…Tough opening-round matches are (5) Na vs. Tamira Paszek then the winner of Venus and (WC) Medina Garrigues, (3) Azarenka vs. Pavlyuchenkova, (11) Petrova vs. a qualifier then likely Kuznetsova, (16) Ivanovic vs. a qualifier then likely her Serb countrywoman Jankovic, (9) Stosur vs. the clay-savvy Suarez Navarro, and (2) Sharapova vs. a qualifier then likely Peng…No blue clay this year…Former champs in the field are Serena Williams (2012) and Kvitova (2011).

“I was more aggressive. I went for my shots much more than him,” Gulbis said. “But he did really incredibly well, as he always does, on the important points. It’s really tough to beat the guy.”

In the second round she upended No. 5 seed Roberta Vinci, and in the quarterfinals No. 3 seed Marion Bartoli. Barthel broke early in both sets, and in both sets held back Errani comebacks.

Maria Kirilenko and hockey star Alex Ovechkin announced their engagement on Monday via twitter.

Women’s Notes: (1) Stosur after a bye could open against Cornet, and (3) Wozniacki after a bye against the Slam winner Schiavone…Pulling from the event were Marina Erakovic, Sara Errani, Kaia Kanepi, and Aleksandra Wozniak…Returning champs in the field are Cibulkova (2011) and Schiavone (2009).

“[In the second set] I was down physically, without energy,” Kvitova said. “It seemed like I was walking, not running. I made a lot of mistakes and went 5-2 down — but then I tried not to think about my shots or tactics and started putting the ball into the court more. Then it was 7-5. I was surprised.”

John Isner and Petra Kvitova are favorites today in Saturday finals in Winston Salem and New Haven.

Wozniacki is the lone returning champion, trying to win her fifth straight New Haven Open. A win this year for Wozniacki would put her in rarified company, as only three players have won a tournament title five years in a row — Chris Evert (Charleston), Steffi Graf (Hamburg), and Martina Navratilova (Eastbourne, Wimbledon and Chicago).

the Top 8 seeds receive first round byes, and tough openers include (15) Kohlschreiber vs. (WC) Baker, winner to meet the Harrison vs. Tomic victor; (10) Fish vs. F-Lo, (8) Monaco possibly vs. The Worm 2nd rd., (4) Ferrer possibly vs. Wawrinka 2nd rd., (14) Nishikori vs. Granoller, winner to possibly meet (WC) Blake; (11) Simon vs. Baghdatis, winner to meet Raonic vs. Gasquet victor; (6) Del Potro vs. Nalbandian/Haas winner, (9) Isner vs. Viktor Troicki, victor to face (WC) Hewitt vs. Mikhail Youzhny winner; (3) Murray possibly opening vs. (WC) Querrey, and (13) Dolgopolov vs. Davydenko

The men’s and women’s Olympic semifinals from London are set, will it be Roger Federer and Andy Murray in a Wimbledon rematch for gold?
