SHANE LOWRY declared mission accomplished as he fired his lowest round of the season to roar into contention for the RBC Heritage.

Seeking his first win since he claimed The Open at Royal Portrush 21 months ago, the Clara star (34) fired an eagle and five birdies in a six-under 65 to move up to tied sixth on seven-under.

He ended his day just four strokes behind the clubhouse leader Corey Conners but by the end of play he was tied for 11th, nine shots behind two-time RBC Heritage winner Stewart Cink (47) who shot a second successive, eight-under 63 to lead by a whopping five shots from Conners on 16-under.

"Pretty happy," Lowry said after he rifled a 184-yard eight-iron to six feet to set up an eagle three at the second, then followed his lone bogey of the day at the third with five birdies, including a brace of near holes-in-one at the 179-yard fourth (five inches) and 201-yard seventh (2 feet).

"I think we definitely looked to have got the worst side of the draw. I knew I needed to go out there and shoot a decent number if I was going to put myself up there for the weekend, so it was nice to go out and do it."

Graeme McDowell missed the two-under-par cut by four shots as a double-bogey six at his 17th hole scuppered his chances and he shot a level par 71 to finish in two-over.

Cink shattered the previous RBC Heritage 36-hole record by three strokes, becoming the oldest player to hold the 36-hole lead at the event.
