Collin Morikawa closed in on his second major at the British Open on Sunday as the American took a three-shot lead over Jordan Spieth into the back nine at Royal St George’s. 

The American, making his debut at the Open Championship, sank a hat-trick of birdie putts at the seventh, eighth and ninth to hit the turn at 14 under par for the championship. He could become the first British Open debutant to win since Ben Curtis’ success 18 years ago.
