Maria Sharapova withdrew from the Fed Cup semifinals against the United States because of a right shoulder injury.
In a statement posted on her website yesterday, the 2006 US Open champion said she had a "tremendous amount of swelling" and doctors advised her to rest her shoulder for the next 10 days.
Sharapova reached the fourth round at Wimbledon last week, losing to eventual champion Venus Williams. Venus and Serena Williams are expected to play for the United States against Russia this weekend in Stowe, Vt.
"I know this withdrawal is very frustrating for all my Russian fans, but I promise you it is way more frustrating for me," Sharapova said. "Nothing would [have] made me happier than beating the Americans on American soil."
Russia's remaining roster includes Svetlana Kuznetsova, Nadia Petrova, and Anna Chakvetadze.
Hall of Fame Championships -- Aisam-Ul-Haq Qureshi relied on his strong serve and consistent play to upset No. 1 seed Mardy Fish, 6-3, 6-4, in another year of misfortune for the tourney's top seeds at the Newport, R.I., event.
Qureshi, a qualifier, repeatedly left Fish struggling on service returns. The No. 1 seed has not won in the tournament's 31-year history on Newport's grass courts.
In other opening-round play, Mischa Zverev defeated No. 7 seed Igor Kunitsyn, 6-1, 2-6, 6-1; Dick Norman beat John Isner, 7-6 (7-3), 6-3; wild card Scoville Jenkins ousted Daniele Bracciali, 6-2, 6-1; and Paul Capdeville topped Nicolas Kiefer, 7-6 (7-3), 4-6, 7-5.
USTA Pro Circuit -- Anna Tatishvili needed a tiebreaker to knock off Billerica's Mary Gambale, 6-4, 1-6, 7-6 (7-3), in the opening round of the Citibank Women's Pro Challenger at Sportsmen's Tennis Club in Dorchester. Top seeds Varvara Lepchenko and Melinda Czink advanced with straight-set victories.
Wimbledon finalist Marion Bartoli and 12th-ranked Daniela Hantuchova are the latest top players to commit to the Pilot Pen tournament in New Haven. They will join fourth-ranked Kuznetsova, No. 6 Amelie Mauresmo, and No. 15 Elena Dementieva in the women's draw of this year's event Aug. 17-25 at the Connecticut Tennis Center at Yale.
