PONTE VEDRA BEACH, Fla. — Robert Streb and Charley Hoffman now have more work to do if they want to make the Presidents Cup team for the first time.

A computer error caused the PGA Tour to readjust the U.S. standings. Streb had been in 11th place, 365 points behind the 10th spot to automatically qualify. Now he is in 16th place, 881 points behind. Hoffman went from 12th place to 15th place.

The U.S. standings are based on FedEx Cup points for the 2015 team. Tour officials realized this week that double the points had been awarded starting with the Frys.com Open in October. Points were not supposed to count as double until the first event of 2015 at Kapalua.

Streb won the McGladrey Classic in October. Hoffman won the Mayakoba Classic in Mexico a month later. Other fall winners who fell in the adjusted standings were CIMB Classic winner Ryan Moore (17th to 21st) and Las Vegas winner Ben Martin (26th to 34th).

The top 10 players in the U.S. standings, including HSBC Champions winner Bubba Watson, were not affected.

J.B. Holmes went from 13th to 11th.

Three tournaments remain for Americans to earn one of 10 spots on the team before Jay Haas makes two captain’s picks. The International team is determined by the world ranking. The Presidents Cup is Oct. 8-11 in South Korea.
