Leona Maguire is well down the leaderboard at the of the LPGA Mizuno Americas Open, sitting in a tie for 93rd after day one in New Jersey.
In what was a disappointing round for the Cavan native, Maguire carded a two-over 74.
She bogeyed four of her opening nine holes, though birdies on the third and eighth saw her at two-over at the midway point.
After a birdie on the 11th clawed her back to one-over, she coughed up a fifth bogey of the day on the 18th.
Jeeno Thitikul of Thailand leads the competition thanks to an eight-under 64. Thitikul enjoyed a bogey-free round and leads by two shots.
Thitikul holds a two-shot advantage over Celine Boutier of France and Hye-Jin Choi of South Korea, having got around the course in just 26 putts.
"I definitely kind of stress about my putting on week off," she said. "I found out I have been doing good. I have - you know, like I had a good stroke but just didn't drop in, so I just trying to make like hand-eye coordination is right and the speed to matching the line."
Boutier made a second-half charge after starting her round on the back nine and shooting 1 over through eight holes.
Her birdie at the par-4 18th was the first of a five-birdie run to shoot her into red figures. She added birdies at the sixth and seventh.
Choi went bogey-free, while a whopping 10 players tied for fourth at 5-under 67. Among them are South Korea's Haeran Ryu - who won last week's Black Desert Championship after falling short in a playoff at the Chevron Championship major the week prior - and Lindy Duncan, who also competed in that playoff and lost to Mao Saigo of Japan.
Nelly Korda recovered from a first-hole bogey to card a 4-under 68 as she tries to build off her showing at the Chevron, where she rallied from a tough opening-round 77 to make the cut.
