It wasn't a good day for Ireland's women's golf team, as both Leona Maguire and Stephanie Meadow struggled to make an impact in yesterday's third round.
Meadow signed for a level par 71, leaving her on one over for the tournament, and still recovering after a poor round of 77 did serious damage to her prospects in Wednesday's opening 18 holes.
Maguire suffered a series of bogeys on the back nine to sign for a disappointing 74, leaving her on level par for the tournament. It was not what she had hoped for, having shot herself back into contention with an excellent six-under-par 65 in the second round at the Rio course
But it just didn't happen for her yesterday, as she slumped to a string of five bogeys in the final seven holes.
World number one Lydia Ko stormed into medal contention with the aid of the day's second hole-in-one in Rio. Ko began the third round seven shots off the lead held by seven-time major winner Inbee Park, but raced to the turn in just 29 shots.
After birdies at the first, fifth and sixth, the New Zealander (19) holed out from 140 yards on the par-three eighth - China's Xiya Lun having done so earlier - and then almost spun her approach to the ninth back into the cup.
