Graeme McDowell carded a 2-under 69 in the final round of the RBC Heritage to join Webb Simpson (71) in a playoff after finishing at 9 under for the tournament. See below for play-by-play.

6:32 p.m.: After Simpson nearly holed his shot from off the green, McDowell left his birdie attempt to win just short. It didn't matter, though, as Simpson missed his 6-footer for par coming back. McDowell has won the RBC Heritage.

6:30 p.m.: Big advantage to McDowell, who is about 12 feet under the hole after Simpson missed the green right.

6:22 p.m.: Both players found the fairway off the tee. McDowell has birdied the 18th twice this week to go with one par and the bogey today. Simpson, meanwhile, has one birdie there this week.

HILTON HEAD ISLAND, S.C. -- Having grown up in Northern Ireland, Graeme McDowell is used to playing in the wind.

How else can you explain his round of 2-under 69?

McDowell birdied the 16th hole, rolling in a 7-foot putt, to get to 10 under before bogeying the 18th hole to finish at 9 under at the RBC Heritage, where the wind has been howling all day.

Webb Simpson tied with McDowell and currently playing the 18th hole.

If a playoff is necessary, players will play the 18th hole.

HILTON HEAD ISLAND, S.C. -- Charley Hofman's chances of winning the RBC Heritage may have just washed away.

Tied for the lead when he got to the tee on the par-3 14th hole, Hoffman left it two strokes back after hitting his tee shot into the water.

It was the 12th ball in the water on the 192-yard hole with water right.

Hoffman made double bogey and is now 7 under, two shots back of Graeme McDowell and Webb Simpson.

It was the first double bogey of the week for Hoffman and the first time he'd made anything other than par on the hole.

HILTON HEAD ISLAND, S.C. -- The final groups are on the back nine at Harbour Town, and the golf course is only getting harder.

The lead has come back to 9 under with Graeme McDowell, Charley Hoffman and Webb Simpson all sharing the top spot. Only McDowell is under par -- Hoffman is 2 over, Simpson even.

Luke Donald and Jerry Kelly, meanwhile, aren't out of yet. Both are at 7 under with Donald already in the clubhouse. Kelly still has four holes to play.

Even Billy Horschel and Kevin Streelman, both at 6 under, aren't done.

If there's an upside, it's that the three of the final four holes aren't the toughest on the course. The 15th, 16th and 17th rank 13th, 15th and 12th.

The 18th, of course, is a different story. It's playing as the third-hardest hole on the course with just four birdies having been made there so far.

In the final round of the 2013 RBC Heritage, the wind causes Webb Simpson’s ball to move as he is preparing to putt on the par-4 sixth hole. A rule change, however, meant there was no penalty on Simpson, who is trying to win for the first time since last year's U.S. Open.

HILTON HEAD ISLAND, S.C. -- The wind continues to blow harder here at Harbour Town and as a result the scores continue to climb.

The scoring average for the field in the final round is hovering around 74 -- three strokes over par -- which makes the scores of Luke Donald, Marc Leishman and Russell Henley look even more impressive.

All are 3 under in the final round and have moved up the leaderboard as a result.

Overnight leader Charley Hoffman is 1 over through his first seven holes and tied for the lead with Webb Simpson, who is 1 under.

Donald and Graeme McDowell, meanwhile, are two back. Donald made the turn in 4 under before dropping a shot on, while McDowell has been steady with seven pars and one birdie.

Four others, meanwhile, are at 7 under, including Leishman.

Prior to the final round of the 2013 RBC Heritage, John Maginnes from SiriusXM PGA TOUR Radio speaks with a number of the tournament leaders.

HILTON HEAD ISLAND, S.C. -- Charley Hoffman is still in the lead at the RBC Heritage -- for now.

Webb Simpson, who is playing alongside Hoffman in the final group, is now just a shot back after a birdie on the par-5 second hole.

Luke Donald, meanwhile, is two back after making the turn in 4 under. he had a chance to get within one but missed a 10-footer on the par-4 ninth.

Remember, Donald lost here in a playoff two years agoand finished in the top 3 in each of the two years prior to that.

Marc Leishman and Kevin Streelman are another stroke back at 8 under -- Leishman has played his first 10 holes in 4 under, while, Streelman is even par.

With high winds whipping across Harbour Town, scoring has been more difficult than any other day this week. Right now, the scoring average on the par-71 is just over 74. That's nearly two strokes higher than Friday when it was 72.1.

In the final round of the 2013 RBC Heritage, Marc Leishman holes a 23-foot chip shot on the par-4 first hole for a birdie three.

HILTON HEAD ISLAND, S.C. -- Charley Hoffman will get his wish in the final round here at Harbour Town.

"I say bring on the wind," he said. "Maybe the wind will blow my ball closer to the hole."

Hoffman is a few minutes from teeing off and the wind is already whipping at 20 mph, and gusts could reach as high as 40-45 mph, which is why the National Weather Service has issued a wind advisory until 6 p.m. ET.

No matter to Hoffman, who leads by three and is used to the wind living in Las Vegas.

"I like the wind," he said.

He also has come to like Harbour Town, which wasn't always the case.

"I would say I wasn't mature enough to play this golf course," Hoffman said. "I didn't understand how to play it. I would get frustrated when I hit the fairway and didn't have a shot at the green. Through the years then I took it off because I didn't think it fit my game.

"Once you learn what side of the fairway you need to hit or the green you need to hit, you have a good advantage being a good driver of the golf ball. I learned that this golf course would be good for me."
