Brittany Lincicome, the first woman to compete in a PGA Tour event in a decade, carded a six-over 78 in the opening round of the Barbasol Championship.
Just the sixth woman to tee it up at a PGA Tour stop and the first since Michelle Wie in 2008, the big-hitting American got her day off to a confident start with three straight pars but then watched her round unravel mixing a triple bogey, a double bogey and two bogeys with a single birdie.
With the top players in the men's game competing in this week's British Open, Lincicome, an eight-time LPGA Tour winner with two major titles, entered the Barbasol with the goal of becoming the first woman to make a cut in a PGA Tour event since Babe Zaharias did it twice in 1945.
If the 32-year-old is to make the weekend she will have to produce some second-round magic as she currently sits at the bottom of the leaderboard, 13 shots adrift of early first round leader Argentine Andres Romero, who signed for a seven-under 65.
"I was a lot calmer than I thought I was going to be, which was a relief," she said in a video published on the PGA Tour's website.
"After that first tee shot I was like, 'Okay, let's go, we can do this'. It was just so much fun being inside the ropes with the guys. I love playing with the guys.
"(It's) literally two bad holes and if I can do better on those two holes tomorrow I'll be pretty good."
