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).

David Ferrer is already into his second semifinal of the young 2013 season while Bernard Tomic stays hot in Sydney.

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).

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

“I know by now the score of a set is irrelevant,” said Roddick, whose only career loss to Muller came at the US Open. “Whether it’s 7-6 or 6-1, it still counts the same. You just try to start over and put some holds together. I was able to [slide] out the second set and I think he might have gotten a little tired in the third.”

Errani will next face Stosur, who beat down No. 15 seed Dominika Cibulkova 6-4, 6-1. The Italian Errani is 0-5 career against Stosur, another mountain to climb.

“I think Victoria is the player to beat,” Williams said. “She has won I don’t know how many tournaments this year alone. That’s an amazing amount. So if you look at the stats, you just have to put her up there as the player to beat.”

Andy Roddick turned back the clock to stun Roger Federer in the third round at Miami Monday night.

The No. 1 seed failed to drop a set throughout the tournament. “Monica has a unique game, a really different style,” Azarenka said. “You really have to dig deep and be patient against her, but you also have to be aggressive. If you stand there and just dig the balls back, she can beat you. So I just tried to stay aggressive and fight for every point and I’m happy how it turned out.”
