NEWPORT, Wales (AP) _ Bob Boyd and Jeff Freeman teamed for an alternate-shot victory and then won convincing best-ball matches with new partners to stake the United States to a commanding lead after two days of the PGA Cup matches Saturday.

The United States had a 9 1/2-6 1/2 lead over Great Britain and Ireland. With 10 singles matches left Sunday, the Americans need only 3 1/2 points for their first victory on foreign soil since 1992.

The PGA Cup, patterned after the Ryder Cup, is only for club professionals.

Leading by a point going into the second day, the Americans won three of the four alternate-shot matches in the morning on the Wentwood Hills Course at Celtic Manor Resort, then split the best-ball matches in the afternoon.

Boyd and Freeman, both former PGA Club Pro champions, defeated British PGA champion Bob Cameron and Tony Nash, 2 and 1.

Freeman then teamed with reigning Club Pro champion Tim Thelen for a 4 and 3 victory, while Boyd and Mike Gill won their best-ball match by the same margin.

Meanwhile, Frank Dobbs continued to struggle on the 18th. He missed a 6-foot birdie putt Friday that would have given the United States a victory, then missed a 2-foot birdie putt Saturday to give GBI a best-ball win.

``It makes you sick,'' Dobbs said. ``At least you've got another day to go back and have a chance to resolve it.''

The United States has an overall 12-4-3 lead in the PGA Cup, which began in 1973.
