When she birdied the 14th hole by puttingt from around four meters and moving into a joint lead with Young, it gave hope for the finish.
Yesterday, Grant finished with four straight birdies on holes 15-18.
But instead, Grant lost to yesterday.
On the short, 129 meter par 3, 15th "hole in one" she had to settle for par and on the 16th she shot the shot into the rough behind the green and was noted for a bogey and disappointed body language in the late summer heat.
The commentators are curious about the Swedish language
She discussed in Swedish with her boyfriend and caddy Pontus Samuelsson and the English commentators on the European Tour's broadcast tried to figure out what they were talking about.
Without having a clue.
At the 17th, Grant had a long eagle putt for an easy birdie and was back in a shared lead.
She made her fourth bogey of the day on the 18th hole after a drive into the rough just off the green.
She then chipped too short and then missed a par putt not even 1.5 meters.
Yesterday, she hit almost all of her putts between three and four meters.
On the last four holes alone, Grant lost five strokes against yesterday.
The competition is played over 54 holes and ends on Saturday.
23-year-old Grant has hit it big, winning seven events this year.
On the occasion of the passing of the British Queen Elizabeth, the competition observed two minutes of silence at 2.20 p.m.
