Months of traveling coast-to-coast in the States and overseas caught up with Ireland’s Áine Donegan on Sunday, as the Clare amateur lost her grip on low amateur honors at the U.S. Women’s Open with an under-the-weather 77 at Pebble Beach.

A back-nine 40 dropped Donegan to a T46 finish at 9-over par for the week, one shot behind Italy’s Benedetta Moresco in the race for the amateur silver medal. Donegan’s 11-foot birdie chance for a share of low am on 18 pulled up 8 inches short in a round defined by low energy.
