Seamus Power and Billy Hurley III are the clubhouse leaders after the second round of the weather-affected Wells Fargo Championship.

The Waterford man followed his opening round of 68 with a one-under-par 71 to move to five under par, with American Hurley carding a 69.  

Things could have been even better for Irish Olympian Power, who coped better than most with the windy conditions at the Eagle Point course. 

The 30-year-old collected four birdies to move into the outright lead at seven-under before bogeys on 15 and 17 dropped him back to the pack.

John Peterson and first-round leader Francesco Molinari are also on five-under but they have their round to finish on Saturday after darkness brought a close to play just after 8pm local time.

Spain's Jon Rahm is one of five men on four under who have completed the round after he shot 71 in testing conditions.

World number one Dustin Johnson, making his comeback from a back injury which curtailed his shot at winning the Masters last month, is on even par after 13 holes, two over for the round.

Graeme McDowell is also in the mix after a topsy-turvy round of 71 moved him to two under for the tournament.

The Ulsterman opened with three straight birdies but had given those shots back by turn. McDowell battled back to four under with three more birdies on the back nine but bogeyed the final two holes of his round.

Shane Lowry faced an uphill battle to make the projected cut of one over par, however. The Clara golfer began the day at three over par but dropped shots at the 10th, his first, and 13th holes to fall to five over with his round still in progress.
