The Canadian duo of Brooke Henderson and Corey Conners had two late eagles and narrowly missed a birdie on the 18th hole of Tiburon Golf Club Friday after the opening round of the Grant Thornton Invitational.
Henderson, of Smiths Falls, Ont., and Conners, of Listowel, Ont., had to settle for a 59, tied for second with Akshay Bhatia and Jennifer Kupcho.
UCLA alums Jake Knapp and Patty Tavatanakit birdied the entire front nine in a scramble format and finished eagle-birdie for a 14-under 58, giving them a one-shot lead.
The tournament has 16 two-player teams from the PGA Tour and the LPGA, the second year of the mixed-team format.
Knapp and Tavatanakit have a natural connection having played for the UCLA Bruins a few years apart. Their team name is “Rocco” — Knapp briefly worked as a bouncer before joining the PGA Tour and Rocco’s Tavern is a popular spot in Westwood for UCLA students.
“Really chill,” Tavatanakit said in describing the day. “I feel like everything was going the way we hoped for. The timing, momentum-building moments were pretty good. We just kept on playing.”
They cooled slightly after opening with nine birdies. Knapp hit a towering shot into about 5 feet on the par-5 17th to set up eagle, and Tavatanakit poured in a birdie putt from about 15 feet on the 18th for the lead.
Knapp won his first PGA Tour title at the Mexico Open. Tavatanakit won her first major as a rookie, the ANA Inspiration.
Maja Stark and J.T. Poston had a 61 and were joined by Sahith Theegala and Allisen Corpuz. Defending champions Lydia Ko and Jason Day were at 62 with Jeeno Thitikul and Tom Kim. Ko and Day were slowed by a bogey on the third hole, rare for the scramble format.
Thitikul last month won the CME Group Tour Championship at Tiburon and the $4 million US prize, the richest in women’s golf.
The format changes to foursomes on Saturday, the toughest of the formats because one golf ball is in play and the teammates alternate hitting shots.
