MANCHESTER-BY-THE-SEA, Mass. - A day after a shaky start, the United States swept all six matches in the Curtis Cup to take an 81/2-to-31/2 lead over Great Britain and Ireland on Saturday.

Alexis Thompson, who has yet to lose a match, teamed with Jessica Korda to beat Danielle McVeigh and Leona Maguire, 3 and 1, at the Essex County Club in the biennial competition between female amateurs.

The United States needs to total 10 points to keep the Cup. The event concludes Sunday.

MEMPHIS - Still recovering from a bout of food poisoning, Robert Garrigus shot a 4-under-par 66 to break out of a pack and grab a 2-stroke lead over Robert Karlsson of Sweden after three rounds of the St. Jude Classic at TPC Southwind.

With four birdies and an eagle against two bogeys, Garrigus reached 11-under 199.

Karlsson, who shot a 68, is within striking distance of becoming the first European to win this event - the tour's third-oldest dating from 1958.

Elsewhere: M.J. Hur and Cristie Kerr sat atop the leader board at 13 under as the third round of the LPGA State Farm Classic in Springfield, Ill., was postponed because of thunderstorms with 46 players on the Panther Creek course. . . . Thomas Bjorn of Denmark shot a second consecutive 7-under 65 to take a 3-stroke lead over Richard Green of Australia in the European Tour's Estoril Open in Portugal.
