DES MOINES (AP) - The mother of Ames, Iowa, basketball star Harrison Barnes says he has narrowed his list of potential college choices to six schools.

Shirley Barnes says her son, considered by many the top basketball player in the Class of 2010, is considering North Carolina, Duke, Kansas, Oklahoma, UCLA and Iowa State.

She says Barnes will make an official visit to North Carolina on the first weekend of September and to Duke the weekend of Oct. 23.

Barnes' visits to Kansas, Oklahoma and UCLA are still being arranged. Barnes, a senior at Ames High, won't make an official visit to Iowa State since he lives just a mile from campus.

Shirley Barnes also says she doesn't believe her son will make a decision before the early signing period ends in November.
