Notes on the US v. Belgium first round Fed Cup tie.

Fernandez took a chance on Vandeweghe after a reportedly bad practice week from Melanie Oudin. Oudin has had a down year since her quarterfinal breakthrough at the US Open last year. Fernandez benched Oudin on Saturday, then on Sunday Oudin showed her veteran composure by not only upsetting Top 10er Francesca Schiavone but blowing out the Italian, allowing her only four games.

U.S. Fed Cup Captain Mary Joe Fernandez will have to choose between the overwhelmed Coco Vanderweghe and Melanie Oudin, who was benched from the first day for a poor practice week, in the first match on Sunday.

Vandeweghe is much like Oudin when she first appeared on tour — not in the best of shape, with a bit of a “gut” visible, and a poor mover. That changed for Oudin when she worked with her trainers to erase the extra body fat and gain speed. Hopefully that is ahead for Vandeweghe, and not just a reliance on a thumping serve and forehand.

Oudin must have put in some horrifying practice sessions this week for U.S. Fed Cup Captain Mary Joe Fernandez to make that decision.

“It’s a very nice feeling. We worked hard to get to this point, finally we made it,” Pennetta said. “In the beginning of the week everyone expected so many things…now we are 3-0 and we can enjoy it.”

Serena and Venus Williams will meet for the 23rd time Sunday in the Doha WTA finals.

Two stunning results this weekend transformed a bland-looking Fed Cup weekend into a shocker.

Nine of the current Top 10 on the WTA rankings are American, Russian or Serb players.
