A day before they are scheduled to stand across the net from each other in the U.S. Open singles quarterfinals, Italy's Sara Errani and Roberta Vinci teamed up to reach the doubles semifinals together.
Their 6-2, 7-6 (2) victory over the 11th-seeded pair of Germany's Julia Goerges and Kveta Peschke on Tuesday assured Errani of moving up to No. 1 in the WTA doubles rankings, with Vinci at No. 2. Errani and Vinci won the French Open doubles title in June.
The American duo of Liezel Huber and Lisa Raymond had been co-No. 1s, but they lost in the third round at Flushing Meadows.
In singles, the 10th-seeded Errani or 20th-seeded Vinci will give Italy its first female semifinalist at the U.S. Open since the professional era began in 1968.
