The 19-year-old from Mid-Herts, put together three very good rounds of 72, 71 and 72 for a one-under-par total of 215.
Hannah, who is in her second year at Baylor University, Texas, finished two shots behind the winner and four shots ahead of the two players who tied third.
Over the three rounds, Hannah had two eagles and eight birdies on the credit side and two double-bogeys and seven bogeys in the debit column. She finished the tournament in great style, playing the final nine holes in three-under-par 33 with a birdie four at the long 11th before an eagle at the 391yd par-four 14th where she holed her second shot.
Baylor team-mate Sian Reddick (Sene Valley) was joint 14th on 223. Sian, from Kent, was the 2004 English strokeplay champion. English girls’ champion Ellie Givens made her debut for Denver University and finished a creditable 30th. Ellie is a member at Blackwell Grange in County Durham.
Meanwhile, another Durham golfer, Anna Scott (Consett & District) returned to the US college circuit with a top ten finish in the Napa River Cardinal Cup at Simpsonville, Kentucky.
Anna, a student at Georgia State University, missed the whole of the 2006-2007 college golf season through injury. She quickly made up for lost time in this event, improving from joint 26th after two rounds to share 10th place in the final standings.
Anna had made her return to competitive action in the English ladies’ championship, where she reached the semi-finals. She followed up with a share of fifth place in the English strokeplay championship.
