Leona Maguire is six shots off the lead after day one of the season-ending CME Group Tour Championship in Florida.
The Cavan golfer, seeking a first win in 17 months, carded a two-under par round of 70.
Maguire's round was soured by three bogeys, including dropped shots on the first and fourth holes, at Tiburon Golf Club.
The 30-year-old picked up shots on the fifth and 13th, and bounced back from a six on the par-five 14th with a run of three consecutive birdies to finish the day tied for 32nd place.
