Leona Maguire eased into the KPMG Women's PGA Championship by posting a level-par 72 in the opening round at the Atlanta Athletic Club.
Arriving at the year's third major off the back of a second place finish on the LPGA Tour last week, Maguire had an early wobble, dropping a shot on the first hole.
However, the Cavan native played steady golf on the front nine and bounced back with a birdie on the fifth hole to get back level.
Another bogey on the eighth meant that Maguire turned at one over par, and remained on one over at 17 after a birdie-bogey combination on 12 and 13.
A fine birdie two on the penultimate hole left Maguire going down 18 with a chance to shoot an under-par round, finishing on a par five, however, she settled for level par heading into Friday's second round.
Four-time Solheim Cup player Lizette Salas leads the way in round one after the American posted an impressive five-under 67.
England's Charley Hull leads the European challenge on four under, while last week's winner, Nelly Korda, is two shots further back after an opening round 70.
Stephanie Meadow was out with the afternoon starters, and the Jordanstown native had a disappointing front nine, making the turn on four over par, which included a double bogey on the ninth hole.
The Irish Olympian then dropped three more shots with bogey, double bogey on 13 and 15 before grabbing her only birdie of the day on 17 to sign for a six-over 78.
