VINH PHUC. — Lois Kaye Go fell short in her bronze medal bid Sunday, closing out with a 70 for 215 and ending up fourth in women’s individual play in the 31st SEA Games at the Heron Lake Golf Course.

Thai Natthakritta Vongtaveelap cruised to the gold medal with a four-under 68, capping her brilliant 54-hole performance she spiked with back-to-back 67s for a whopping 14-under 202 total.

Singapore’s Aloysa Atienza Mabutas provided the final day fireworks as she scorched the par-72 layout with a tournament-best 65 to rally from joint fourth and snatch the silver medal on a 209 total that included a 74 and 70.

Malaysia’s Jeneath Wong fired a 69 for the bronze with 209.

Ms. Go wound up six strokes farther back at fourth at 215, her bid stymied by a shaky 76 in the first round. She bounced back strong with a second-round 69 but failed to sustain her charge in the last 18 holes and settled for a two-undercard.

Mafy Singson, who also fought back with a 70 Saturday, struggled with a 73 and finished with 219 while ICTSI teammate Rianne Malixi finally broke par but her 71 could only net her a total of 221, marred by a 76 and 74.

The Thais are all poised to sweep the individual gold medals with Asit Areephan leading at press time in men’s play. He led the field at 138 after 36 holes with compatriot Weerawish Narkprachar in second with 140 and Ratchanon Chantananuwat in fourth at 142 behind Vietnam’s Minh Nguyen Anh and Indonesia’s Amadeus Susanto, who both had 141s.

The chase for team gold starts Monday with the quarterfinals, also at the Heron Lake layout, where seedings are based on the players’ finishes in individual play.

The semis will be held Tuesday with the gold and bronze medal matches set for Wednesday.
