Play has been suspended for the day with three players tied at the top of the leaderboard at the RBC Heritage on the Harbour Town Golf Links, at the rain affected end of the day. Kevin Streelman, Charley Hoffman and Steve LeBrun are at -6 under par for the competition. Steve LeBrun, Kevin Streelman and Charley Hoffman / Lecka / Getty Images In the wet, windy and difficult conditions Kevin and Charley both had second rounds of -1 under par, 70 for their totals, with Steve LeBrun shooting a second round -3 under par 68. Luke Donald also had second round of -3 under par, and shares T4 with Bill Haas, who came home in -2 under par for the day, both of them at -5 under par. The next group of players, seven in all, are at -4 under par, they are all handily placed to go forward in this competition tomorrow. They are; Johnson Wagner, Rory Sabbatini, Graeme McDowell, D.H. Lee, Pat Perez, and two Aussies, Stuart Appleby and Marc Leishman. All these players are in the clubhouse, but the cut line has still to be determined with 17 players still to complete their second rounds. The current cut line is at +1 over par, but could easily move to +2. Pat Perez said his trying to stay calm; " I'm trying to stay level, which is always, for me, trying to stay on a high, I've really worked hard on it this year. I don't have the ups and downs. It's hard, especially for me, because I've done it my whole life. But to say, that's not going to bring me down, let's try to make 5 instead of 6. And the next hole it's basically done. I didn't think I'd make a lot of birdies, but I seem to be hitting it closer than I ever have out here." One of those players teetering on the current cut line at +1 over par is Jesper Parnevik, and he is on the 18th hole with an agonising five foot putt left for his par. If he misses that tomorrow, he would drop to +2 over and that would move the cut to that number as well. Obviously there are other players on the course who could make a birdie and change things back again, it will be a very interesting early start tomorrow. Of those who have definitely missed the cut are; Vijay Singh +4, Ernie Els +4, John Daly +10, those are just a couple of the higher profile guys who have struggled in this competition.
