Errani and Vinci: frenemies!

I love this adorable photo gallery celebrating Italian tennis stars Sara Errani and Roberta Vinci. Together they make a formidable doubles team and won this year's French Open. Alone, they will face each other today in the singles' quarterfinal, the first time for either player to reach the quarters at the US Open. However that goes, an Italian player is guaranteed a spot in the semis, likely to face Serena Williams.
