After Da Silva dropped a bogey on the challenging 501-yard 18th hole where the players were struggling to reach the green, Rai sank a 20-footer to ensure he stayed level with the experienced Brazilian. \"It was tremendous. As a professional golfer, you must know every shot counts out here. I was mentally prepared for that putt,\" said the 24-year-old Rai, who fired birdies on the second, ninth, 11th and 17th holes.In-form Da Silva produced some spectacular shots, including a monster birdie putt off the 14th green to give himself a chance of winning a title in his Asian Tour debut season.\"I\'m feeling very confident and I feel my putting is working again. I\'ve been hitting the ball reasonably well but my putting hasn\'t been there. But the last couple of weeks I\'m beginning to find that form back again,\" said the 39-year-old.\"The winds were so strong on the 18th and I was actually hoping for the officials to call off play. I couldn\'t even make it to the front of the bunker in two. I\'ve been in this position before and I\'ll try to stay patient, focus on my shots and hopefully they will be good enough to win this tournament.\"
