Gary Evans will lead the English challenge going into the final two rounds of the Open after carding a 75 to lie five shots off the lead.
Evans could not match his first round score of 71 but did enough to maintain his hopes of another challenge after finishing fifth in last year's championship.
The Worthing golfer moved up to joint third at one point with a birdie at the seventh but ended the day in joint 16th.
Mark Roe lies just one shot behind Evans on five over after a stunning start put him on the way to a one-under 70.
Roe opened up with six threes in a row which included an eagle at the fourth hole and birdies at the first, second and fifth.
"I'm wondering has anyone had six threes in a British Open," said Roe, who has
just three European Tour victories in a career going back to 1981.
"It was a rollercoaster run but I get used to that. I made one mistake and that was my tee shot at the par five and it cost me an eight.
"I hit a bad tee shot and it went from bad to worse. I could see the leaderboard and it said I was lying third. But this golf course is brutal."
Nick Faldo and Ian Poulter will play together on Saturday after making the cut by just one shot.
Faldo followed his first-round 76 with a 74 and Poulter saved himself with a one-over 72.
But young hopefuls Justin Rose, Paul Casey and Luke Donald all bowed out along with Lee Westwood, who was just one shot adrift of the cut-off mark after a 75.
Rose finished on 17 over after just one birdie in 36 holes, Casey on 14 over and Donald on 13 over.
