SINGAPORE — America's Stacy Lewis pulled off the shot of a lifetime Sunday on the way to a narrow one-stroke win after a nerve-shredding final day at the HSBC Women's Champions in Singapore. Lewis, the two-day leader, was locked in a three-way tie with Choi Na-yeon and Paula Creamer when she unleashed a blistering hybrid shot from the fairway on the par-five seventh, landing just inches from the hole. The tap-in eagle gave Lewis the outright lead ahead of Choi, the world No. 2, and whiplash victim Creamer, and despite bogeys on 15 and 17 in a gripping close she held on for her sixth career win. Lewis, who spent most of her teenage years in a back brace to correct a curve in her spine, carded one-under-par 71 on a cloudy day at par-72 Sentosa Golf Club for an aggregate score of 15-under 273. Choi finished with 72 for 274 while Creamer, also playing the final group and still feeling whiplash injuries after a car crash last Sunday in Thailand, carded 71 to finish a shot further back in third. Thai sensation Ariya Jutanugarn, 17, cruelly robbed of victory last week by a triple bogey on the final hole, signed for 71 to finish fourth, five strokes off the winner, with Candie Kung, Jessica Korda and Danielle Kang sharing fifth. World No. 1 Tseng Yani showed her disgust at her closing score of 74, to wind up 13 off the lead on two-under-par 286, by tossing her ball into the lake after holing out on 18. Van der Walt wins Dawie van der Walt won his first European Tour tournament Sunday by finishing two shots ahead of fellow South African Darren Fichardt in the Tshwane Open. Van der Walt fired a five-under-par final round 67 for a total of 267 over the Ernie Els-designed Copperleaf Golf and Country Estate while Fichardt closed with a 69 on the 7,791-yard layout. A two-meter, 110-kg giant, Cape Town-born Van der Walt was one shot ahead of four-time European Tour winner Fichardt at the turn and extended it with a birdie at the par-five 15th on a hot, overcast afternoon. Both title challengers parred the last three holes and Van der Walt collected a 237,750-euro ($310,690) check and a three-year exemption from qualifying for European Tour events. The winner of the inaugural Tshwane Open was a model of consistency over the four days of a tournament hit by two-hour delays Friday and Saturday when seasonal thunderstorms rolled over the course south west of here. “I hit the ball really well this week and probably missed only six or seven greens in regulation,” said the slightly nervous champion after receiving his winner's check and trophy. “My tee-to-green game was good, my putting solid, and to bogey only one hole throughout the tournament on such a long and challenging course was really awesome.” — Agencies
