INDIANAPOLIS – Lexi Thompson shot a closing round of four-under 68 on Saturday to win the inaugural Tech Championship tournament, the last tune-up before the final major championship of the season. Thompson’s four-shot victory at the Brickyard Crossing golf course gave her a 19-under 197 in the 52-hole event. “It was such a great week overall and it was a huge honour to be here in Indiana …. definitely a memory that I’ll never forget,” the 22-year-old American said. New Zealand’s Lydia Ko shot an even-par 72 Saturday to finish alone in second at 15-under 201 for her first top 10 placing in three months. Australia’s Min-Jee Lee (67) placed third, while fourth place went to rookie Olafia Kristinsdottir, the first USLPGA Tour player from Iceland. Canada’s Brooke Henderson (69) and South Africa’s Ashleigh Buhai (71), American Lizette Salas (69) and South Korea’s Kang Hae-Ji (68) tied for fifth at 12 under, seven strokes back of Thompson.
