Goosen, last months champion of the United States Open, began his round in stellar fashion, recording birdies at Nos. 1 and 2, and then eagling the par-5 3rd.
Through his first seven holes, the big South African was 6-under, and following additional birdies at the 10th, 11th and 12th, it seemed the easy-going and smooth-swinging star might take a crack at 60.
However, a poor drive at No. 13 ' a par-5 ' resulted in his only bogey of the day.
Goosen atoned for the mistake at the par-3 17th, however, with one final birdie, but ended a bit short of everyones hopes.

I knew the chances were there, but the last few holes are tough, said Goosen following his round. I could have been 11-under if I had birdied those two (the 13th and 14th), but I would still have needed another one somewhere. Im happy with the round, though, and hope I can build on it.
While Goosens 62 matched the existing course record that he shot himself at Loch Lomond four years ago, the round did not count due to the lift-clean-and-place format that was the rule on Thursday.
Heavy overnight rains forced the ruling, and also caused a four-hour delay at the start of the round.
As a result, several groupings did not finish their rounds before darkness set in.
Jarrod Moseley and Elliot Boult managed to finish, however. They each shot 65s to sit three behind Goosen at minus-six come days end.
They were tied at the mark with young Australian superstar Adam Scott, who was at minus-six through 16 holes.
Boult couldnt have been happier with his score, as he wasnt even supposed to be playing this event.
The New Zealander received the call to action as a replacement for defending champion Ernie Els, who withdrew with back problems.
Ive got Ernies locker so hopefully I can go on and play like him this week, said Boult, who has missed the cut in three of his last four starts. Its a good omen ' and Im right next door to Colin Montgomerie as well. I am a bit lucky to get in so late but I would rather play here and try to get into the Open that way then go to pre-qualifying.
Therell be no pre-qualifying this season for Danish star Thomas Bjorn.
The winner of this years Dubai Desert Classic, Bjorn ended one shot further back, having made it to 5-under through 13 holes when play was called.
Local favorite Montgomerie had a rather indifferent round of 1-under 70, however, and had but one thought to offer at the end of the day.
It was Goosens day, claimed Monty.
Retief couldnt have agreed more. And following his beautiful performance at Southern Hills last month, hes hoping for more and more in the future.
Obviously I am a lot more confident out there now, he claimed. You realize you can play under pressure condititions.
Round One of the Scottish Open will conclude Friday morning, with the second round commencing immediately thereafter.
