Canada's Brooke Henderson is No. 1 on the LPGA Tour standings.
She was elevated to the top spot on the Race to CME Globe rankings on Monday after winning the Hilton Grand Vacations Tournament of Champions.
Henderson won the season-opening elite 29-player tournament by four strokes.
The native of Smiths Falls, Ont., now has 13 professional wins, the most in Canadian golf history.
Henderson finished 2022 third in the Race to CME Globe rankings and seventh in the Rolex Rankings.
The 25-year-old remains in seventh in the Rolex Rankings, which evaluate a player's performance over a rolling two-year period weighted in favour of the current year.
The Rolex Rankings are sanctioned by 10 women's professional golf tours across North America, Europe, Asia, and Australia.
