"Math just didn't make much sense," observed American golfer Amy Olson of the challenges of navigating a route through the sand dunes of Royal Troon in the AIG Women's British Open.
Although the numbers eventually added up for the American who shot an opening round of four-under-par 67 that gave her a three shot-lead after a weather-hampered first round that featured strong winds and intermittent rain showers.
Olson, whose best finish in a Major came with a runner-up finish in the 2018 Evian Championship, kept her composure to claim a three-stroke lead over fellow-American Marina Alex and Germany's Sophia Popov.
It was a day when only three players managed to better par and, for the most part, players were in a battle of attrition with the strong winds, exemplified by Olson claiming to hit a wedge 80 yards into the wind at one point and using the same club for a 176 yards shot downwind.
While Olson kept her focus in difficult conditions to assume the first round lead, the three Irish players in the field were thrown into a battle to survive the cut.
Stephanie Meadow, with an opening 75, four-over-par, for tied-52nd, fought back from three bogeys in her opening four holes to get into a position to make the cut.
Leona Maguire and amateur Olivia Mehaffey each signed for 77s, and were left with work to do to survive the 36-holes cut. Maguire had a rollercoaster round that featured two double-bogeys, three bogeys and a lone birdie on the par five 16th and, in tied-89th position after the opening round, has a bit of work to do to make it into the weekend.
Mehaffey, from Co Down, had one double-bogey, five bogeys and a birdie on 16 in her opening round.
Even before a ball was hit in anger, there was some drama when world-ranked number 18 Jessica Korda withdrew on medical grounds which were "unrelated to Covid-19".
Her sister, Nelly, the world number four, shot an opening round of 72, one-over-par.
