Radwanska and Kerber fall on Day 8
The Radwanskas won’t want to hear the name “Roberta Vinci” brought up at the dinner table anytime soon.
Urszula was knocked out in the first round by the 29 year-old Italian, and #2 Agnieska was upset today 6-1, 6-4, eliminating yet another big name from the Open field. “I think I really had the worst day.”
Four double faults led the Polish star to five service breaks, and now the favorites left are top seed Victoria Azarenka and Serena Williams, who advanced in straight sets once again, and who Agnieska thinks will win. Serena did lose her doubles match, however.
The other big upset of the day was Sara Errani  over Angelique Kerber , although it wasn’t much of a lopsided matchup. Kerber, picked to win by WFUV’s Ben Kelly, failed to move on to the Quarterfinals 7-6, 6-3.
As for the nightcap, Andy Murray  easily handled the big-serving Milos Raonic  6-4, 6-4, 6-2.
Earlier in the day, American Mardy Fish withdrew from the US Open due to health concerns. That sent Roger Federer to the Quarterfinals. Other winners included Ana Ivanovic , Marin Cilic , and Tomas Berdych .
