Number of strokes under par that Rory McIlroy stood Thursday after the first round of the WGC Mexico Championship. Starting on the back nine at Chapultepec Golf Club in Mexico City, McIlroy rattled off six birdies and an eagle in his first 13 holes. Tree trouble off the tee at the par-5 sixth hole led to a bogey before he picked up another birdie to shoot 63. McIlroy, 29, a four-time major champion from Northern Ireland, is seeking his first victory on any tour in nearly a year, since the 2018 Arnold Palmer Invitational. American Dustin Johnson stood second at 7-under 64 in the elite 72-man event. Tiger Woods, who hit his opening tee shot out of bounds left en route to a double bogey, shot 71 (scores).
Number of years since Andres Romero, the first-round leader at the Puerto Rico Open, posted his lone victory on the PGA Tour. Romero, 37, of Argentina, shot a bogey-free 6-under 66 at Coco Beach Golf & Country Club at Rio Grande, Puerto Rico. He leads Austrian Sepp Straka by one stroke (scores).
First-round score for South Korea’s Eun-Hee Ji, who held a two-stroke lead in the Honda LPGA Thailand. Ji, 32, a five-time winner on the LPGA, won the Diamond Resorts Tournament of Champions in January. She stood 9 under after 18 holes at Siam Country Club Pattaya’s Old Course in Chonburi, Thailand. American Danielle Kang, South Korea’s Jenny Shin and Australia’s Minjee Lee shared second place at 65 (scores).
