Graeme McDowell remains in the hunt for the Zurich Classic title, sitting just outside the top ten, five shots off the lead going into the final day in New Orleans.

Playing alongside Sweden's Henrik Stenson, the duo carded a third round 66 to sit on 18 under par, five shots off leading groups of Jon Rahm and Ryan Palmer, and Scott Stallings and Trey Mullinax.

McDowell and Stenson shared three under on the front nine in the third round's best-ball format, and added three further birdies on the back nine.

Unfortunately, their bogeys proved to be in-sync, which saw the pair lose two shots on the 12th and 17th holes respectively. McDowell holed out from about 80 yards to make eagle on the short par-four 16th to get the round back to six under.

The final round will return to the alternate shot format, which will put pressure on all contesting partnerships with lots of fluctuation expected at the top of the leaderboard.

After a more than seven-hour rain delay on day one, teams got back on track to complete the third round on Saturday, with Rahm and Palmer playing 30 holes and Stallings and Mullinax completing 27 for a share of the lead at 23-under 193.

In the alternate-shot second round, Rahm and Palmer carded a seven-under 65 followed by a 64 in the best-ball third round, making just one bogey when both players found the water off the 17th tee.

Rahm gave a solid performance in the third round, making eight birdies, with Palmer saying he had learned a lot from the Spaniard.

Seamus Power and his Canadian partner David Hearn, meanwhile, sit in 21st place heading into the final round in Louisiana.

Power and Hearn carded an eight-under 64 in the third round, with the pair carding a bogey-free 18, thanks to the best-ball format and now sit seven shots off the lead in a tie for 21st place.

"He's just fun to be around," said leader Palmer, speaking about playing partner Rahm to the PGA Tour website.

"He's actually a great guy. I've enjoyed every second with him. When you're up close and personal and watching it and see the shots he can hit around the green, you know, his short game is phenomenal. You can learn something from that, too, so I learned a lot. Honour to be a part of it."

Stallings and Mullinax share the lead with the Spanish-American duo after following up their second-round 70 with a blemish-free 62 in the third round, including an eagle from Mullinax on par-five second.

Brandan Grace and Justin Harding sit in third one shot back, while England's Tommy Fleetwood and Spanish team-mate Sergio Garcia finished in a tie for sixth at 19 under ahead of Sunday's alternate-shot final round.
