NEWTOWN SQUARE, Pennsylvania (Reuters) — Briton Justin Rose tamed the tough Aronimink course with a commanding display to earn a four-shot lead after the third round of the AT&T National on Saturday.

Rose, who made just one bogey in a three-under-par round of 67 in bone-dry afternoon heat, moved within sight of his second victory in three starts on a 10-under total of 200.

“Today was a really good round in a lot of ways,” Rose told reporters.

Burly Swede Carl Pettersson (65) shot the day's best score to move into a tie for second with South Korea's Charlie Wi (70) on six-under, while Tiger Woods's title defence is all but over, the American falling 13 shots off the pace after posting a 70.

Rose, a stand-out on the US Tour in recent weeks, has some demons to contend with having surrendered a three-shot lead going into the final round in Hartford last week.

His final-round freeze scuttled his bid for two wins in two starts after he won the Memorial last month, his first PGA Tour victory.

“My game wasn't that good at Hartford,” he said. “I feel a lot more comfortable with more aspects of my game this week. Tomorrow, the challenge is to be as loose as possible. I'm more excited to put into play the lessons I learnt at Hartford. What I'm doing well is not carrying any baggage over from one week to the next.''
