Dustin Johnson delighted by opening-round showing at The Open

Dustin Johnson has admitted that he was delighted with his first-round performance at The Open, having taken a one-shot overnight lead.

The American managed to get the better of compatriot Jordan Spieth at St Andrews, as he chases redemption from his US Open slip-up against the same opponent last month.

After opening with only the third bogey-free round of his Major career, Johnson insists that the events of Chambers Bay are now firmly behind him.

"I played really well, did everything I was supposed to," he is quoted as saying by The Guardian. "I couldn't control what the ball was doing on the greens there.

"There's really no bad feelings from that, only good. I played really well and then it carried over to today. I played really well today."

Johnson is one shot clear of a group of six, which includes Englishman Danny Willett and 1999 champion Paul Lawrie.
