England's Luke Donald moved to within a shot of the lead at the halfway stage of the RBC Heritage in South Carolina after a second round 68.
The world No 6 followed up his opening 69 with a three-under-par round to move to five under for the tournament, tucked in behind leading American trio Kevin Streelman (70), Charley Hoffman (70) and Steve LeBrun (68).
The 35-year-old former world No 1 has had a slow start to the season, with just a solitary top 10 and is currently down in 70th place on the FedEx Cup standings.
But he is showing signs of a return to his best form as he mixed five birdies with just a couple of bogeys on the tough Hilton Head links.
Donald, who was edged out by American Brandt Snedeker in a play-off for the 2011 Heritage title, was delighted to improve on his opening round of 69.
"Today I hit it a lot better," he said. "It was tougher and the wind was up but I had a lot more control today.
"I hit a lot more fairways, a lot more greens. I managed my game very well. It was more of a Luke Donald round today which is pleasing."
Northern Ireland's former US Open champion Graeme McDowell is a shot further back after an impressive four-under 67.
The Northern Irishman carded five birdies and just one bogey to record the joint-best score of the day, along with Australian Matt Jones who bounced back from his 75 on Thursday in style.
Overnight leader Brian Davis did not have a good day, however.
The Londoner, who three years ago penalised himself in a sudden death play-off at this tournament, held a one-shot lead over Streelman and Hoffman overnight after carding a 65 on Thursday.
But as one of the late starters on Friday he endured the worst of the blustery conditions and after going out in 40, he eventually signed for a four-over 75. At two under for the tournament he is four shots off the lead.
Play was halted late in the day due to the threat of lightning as heavy thunderstorms closed in and 17 players will have to complete the second round on Saturday.
The cut is projected to fall at one-over 143 with Snedeker, Ernie Els and Vijay Singh among those in danger of missing out.
