World number one Luke Donald has revealed that he is happy with his "workmanlike" opening round of 70 at the Open Championship.

The Englishman putted a birdie on the third at Royal Lytham & St Annes before dropping a shot on the last hole of the day to end on level par.

The 34-year-old believes that he can mount an attack at the top of the leaderboard if he starts sinking a few more birdies.

"I think mentally I was in a good place. I felt like I wasn't getting too much ahead of myself," he said.

"I hit a lot of very solid shots but I didn't get as much out of it as I would have liked. But really it was kind of an easy 70. It wasn't one where I was getting up and down and really struggling.

"It was very workmanlike. If I continue to do that I know the putts will start to drop and I can make a few birdies."

Australian Adam Scott currently leads the field by one shot on six-under-par.
