The Park family — No. 2-ranked Inbee Park and her husband and caddie Gi — led the way after the opening round of the HSBC Women’s World Championship on Thursday.
Park birdied two of her final three holes in a bogey-free round for an 8-under 64 and a one-stroke lead at the LPGA Tour tournament.
“I think I’m going to give him 10 (out of 10) and probably 10 for the rest of the week because I’m really thankful that he’s doing this for me and in this heat," Park said. “I’m just really thankful that he’s carrying the bag."
Park's regular caddie, Brad Beecher of Australia, was not able to carry her bag because of coronavirus quarantine restrictions.
Park is the defending Olympic champion and has two previous wins at the Singapore tournament, in 2015 and 2017.
Hee Young Park (65) holed out from the fairway for an eagle to start her back nine and birdied three of her final five holes and was a stroke behind. Five players were three strokes off the lead in third with 67s, including Women's British Open champion Sophia Popov.
Lydia Ko, whose win in Hawaii a week ago moved her up to No. 7, shot 69, while No. 1-ranked Jin Young Ko had a 71 and No. 5 Danielle Kang shot 72.
ANA Inspiration winner Patty Tavatanakit shot 70. The 21-year-old Thai, who played college golf at UCLA, won the first major championship of the year in her rookie season on tour.
