McDowell made most of his gains on the back nine of the less exposed Plantation Course after starting from the 10th hole.

The Portrush golfer made back-to-back birdies threes on the 12th and 14th holes and also added birdies at the two par-fives on the back nine to turn in four-under 32.

At seven under, McDowell looked well placed to make a charge at the top spot on the leaderboard, but he would finish the day on the same mark after a bogey on the fifth and a fifth birdie of the day on the short seventh.

Chappell broke clear of the field thanks to an eagle three of the par-five 15th at the Seaside Course, chipping in from the greenside bunker.
