A wonderful third round performance from Lee Westwood in The Open has seen him pull two shots clear of the field at Muirfield. Lee Westwood / Getty Images Lee Westwood will take a two shot lead into the final round of The Open tomorrow at Muirfield, thanks to a third round of -1 under par, and a -3 under total as he chases his first Major victory. Lee said he is aware for what it will take to win tomorrow; "I know what to expect tomorrow, I know what to do, I know what it takes. My emotions were pretty calm all day although when something exciting happened like that eagle I allowed that to pump myself up. You don't really expect to make those but I could see the line easily breaking in off the hill.It's just a case of believing you are good enough to win. When you analyse it, you don't want to say it, but tomorrow is just another 18 holes. I'm playing well and putting well and there's no reason why I can't carry on." Hot in pursuit will be Americans Tiger Woods and Hunter Mahan, both players starting their final rounds at -1 under par. Hunter had a fine -3 under par round of 68 today, while Tiger fell back with a +1 over par round of 72. In fourth place is Adam Scott, he had a third round of -1 under par 70 and will stand on the first tee tomorrow at even par. Defending Champion Ernie Els has not given hope of retaining The Open title, but he has a monster job on his hands. Ernie had a -1 under par third round of 70, and will start the last round at +5 over par, and thinks he could still make it; " If I'm within six or seven shots of the lead you never know. It happened last year, I'm not saying it's going to happen every day but anything can happen in The Open. You're hoping not to be too far off going into the final round and then you're hoping for that quick start. Somebody can get hot and from where I am, if the leaders don't get hot, you're in the ball game, that's what I'm hoping for. Get that birdie at the start and then to try to get the guys to see your name, and then hopefully that makes a difference.I'm a competitor, I'm not going to lie down until the 72nd hole, that's just the nature of what's going on out there. It's such a great Championship but obviously I'm trying to play better than where I am."
