William Woods' lone representative for round four, Maria Zrodowska, recorded her worst score of the four days at the 26th annual Women's Golf National Championships at Rose Creek Golf Course in Oklahoma City.
She finished the day with an eight-over-par, or 80, adding to a 306 four-day score, to enter a nine-way tie for 29th place.
Zrodowska started and ended the back nine with a double bogey. In between, she sunk six pars and a birdie, posting a three-over-par through the first nine.
Her bad start to the front nine put Zrodowska up four more strokes after the first three holes. She finished the round with four pars and a bogey.
Zrodowska shot a 74, 78 and 74 through the first three rounds in this year's national championships. She tied for fifth in the 2019 national championships.
