Bishop Gorman product Inbee Park had a sensational performance on the Rio de Janeiro golf course Wednesday to open the Olympic women’s tournament, but it wasn’t enough to lead the pack.

Ariya Jutanugarn of Thailand finished atop the leaderboard after Round 1, and is the first 18-hole leader in the history of women’s golf in the Olympics.

Jutanugarn had a little bit of everything on her scorecard and wound up with a 6-under 65 for a one-shot lead over seven-time major champion Park and Seiyoung Kim, both of South Korea.

This is the first time for women’s golf to be in the Olympics since the Paris Games in 1900, and back then it was only a nine-hole competition.

Park, who committed to UNLV but turned pro before college, was playing top competition for the first time in two months because of a thumb injury. She was bogey-free in her round of 66 and recorded five birdies.

Lydia Ko, the No. 1 player in women’s golf, holed out from 135 yards on the 15th hole for eagle. She shot 69 and was four shots back.
