NDIAN WELLS, Calif. -- Robby Ginepri became the first American to win his way into the second round of the BNP Paribas Open by beating Paoli Lorenzi of Italy 1-6, 6-3, 6-4 on Thursday.
The oft-injured Ginepri was joined later by Sam Querrey, a 7-6 (1), 6-4 winner over fellow American Tim Smyczek. But the other U.S. players -- Jack Sock, Jesse Levine and Rhyne Williams -- were sent home after three-set losses.
Harrison is in the same quarter of the tournament bracket as No. 4 seed Andy Murray.

Jelena Dokic retired after the first game of her match with Gisela Dulko of Argentina because of a right wrist injury. Greta Arn of Hungary lasted five games and was down 4-1 in the opening set of her match with Johanna Larsson of Sweden when she retired with neck problems.
Other men advancing to the second round were Andreas Seppi of Italy, Santiago Giraldo of Colombia, Philipp Kohlschreiber of Germany, Sergly Stakhovsky of the Ukraine, Matthew Ebden of Australia and two Spaniards, Pablo Andujar and Albert Ramos.
Varvara Lepchenko, who was born in Uzbekistan and lives in Allentown, Pa., also advanced with a 7-6 (3), 6-2 victory over Alexandra panova of Russia.
