Australian rookie Stephanie Na finished in a tie with seven other women for third as Diana Luna claimed her second victory in a week at the SAS Ladies Masters in Norway. Na hit a blistering final-round 68 to climb the leaderboard and finish at 10-under overall, two strokes behind Luna. Melissa Reid was one stroke back after a 71 while Trish Johnson was one of seven women in a tie for fifth, one place ahead of Rebecca Hudson. Luna sealed her third career title and her second in a week following her victory at the AIB Ladies Irish Open at Portmarnock Links on Sunday. The 26-year-old from Rome carded rounds of 67, 70 and 70 for a total of 12-under, finishing one stroke clear of Laura Cabanillas from Spain. She came from three shots behind the second-round leader Veronica Zorzi, also from Italy, a two-time French Open champion who slipped back to 10-under in a share of third with seven other players.
