Amy Olson leads US Women's Open after hole-in-one on 16th

• American aces par-three 16th at Cypress Creek
• Tournament rescheduled from June due to Covid-19 pandemic

American Amy Olson's bid for her maiden major got off to a spectacular start as a hole-in-one and three birdies gave her the first-round lead at the US Women's Open in Houston, Texas on Thursday.

The 28-year-old started her day on the back nine and raised her arms in triumph after hitting the ace on the par-three 16 at Cypress Creek - one of two layouts being used at Champions Golf Course because of reduced daylight.
