The Australian challenge came too late as irrepressible world No.1 Jeeno Thitikul held her nerve to record an emotion-charged and hugely popular home-town triumph at the LPGA Thailand.
Thitikul carved out a tense final-round four-under-par 68 to edge out Japan's gallant runner-up Chizzy Iwai by a shot at the Siam Country Club's Old Course on Sunday.
With her non-travelling mother making the short trip to Pattaya to watch her daughter for the only time all season, Thitikul collected herself after missing the green at the last hole to eke out a nerve-wracking, tournament-winning par.
