Jason Day has failed to capitalise on multiple birdie chances on the front nine in the third round of the Masters and Adam Scott is treading water as Jordan Spieth continues to lead.
Day missed five birdie chances from inside 15 feet on the front side on Saturday, making the turn at one under on his round to be four under and tied 13th, 11 shots behind leader Spieth.
The young American had two early birdies and a bogey to sit at 15 under, now six clear of his nearest chasers.
Three-time Masters winner Phil Mickelson is making a charge, three under on his opening seven holes to be at nine under where he shares second with Charley Hoffman (six holes).
Dustin Johnson is fourth at eight under (six holes) where he is joined by world No.1 Rory McIlroy who is six under on the round through 15, trying to apply some heat.
Fourteen-time major winner Tiger Woods is also trying to surge, four under on his round through 12 to be six under.
Scott, the 2013 champion, is even par on his round to be three under, needing a miracle on the back nine to be in the conversation.
Day birdied the second and seventh holes but missed a five-foot chance on the third, a seven-foot chance on the fifth, a 10-foot chance on the sixth, a 15-foot chance on the eighth and a five-foot chance on the ninth.
Had he even nailed half of them he might have been able to get back into the tournament.
Scott birdied the second and third holes to start strong but unravelled with a bogey on the fourth and a double bogey on the fifth.
The Queenslander failed to get up and down from a bunker on the fourth and then nuked his approach on the fifth into dense bushland, forcing him to take an unplayable and repeat his shot.
