He will take a one shot lead heading into the third round, moving day on Saturday, and said he was comfortable at being in front; "I think I've had to learn to be a good front-runner, I maybe wasn't quite comfortable in that position at the start of my career, especially 2011 in the Masters. I was four ahead and I wasn't quite comfortable in that position." "It's taken me a couple of years to grow into that and my mindset has stayed the same since that day at Augusta. If I'm two ahead going into the weekend here, I'm going to try to get three ahead, and if I'm three ahead, I'm going to try to get four ahead." "I'm just going to try to keep the pedal down and get as many ahead as possible. I went into protection mode once in my career and that did not work out very well so I said would never do it again." "I think it has happened to me for the better. I've put a little bit more time into my golf and refocused in a way. It's the only thing I have, I've got my family and my friends, but I just immersed myself in my game." "I've practised hard and I've done all the right things and I'm reaping the rewards. Golf is the number one priority to me and while I'm on this run of form I want to try and keep it going as long as possible." "I'm going to keep working hard and try and get even better. Hopefully I can do that over the next few years and hopefully you'll see golf like this more often from me." Tied in second place are Jason Day and Jim Furyk, both on -8 under par for the competition. Jason carded the best round of the day, a -6 under par 65, while Jim had a more modest -3 under par 68. Lee Westwood wilted under pressure, carding +1 over par 72, dropping to -5 under par. Phil Mickelson had a good day, -4 under par 67 and is currently tied in 7th position at -6 under par. He hopes to make the Ryder Cup Team on merit; "I'll be honest, there's not too many people out of the mix. There's still time now, and there's still time between now and September 2 to show. There's three tournaments between now and September 2. I don't know how many tournaments these guys are going to play, but there's still time. " " It's anybody's guess who is going to make the team after Sunday this week, too. I'm going to make the team, Tom. I'm going to make the team. I don't want you to have to use a pick to pick me." Tiger Woods missed the cut, whoever advised him to return to golf so soon after surgery needs their head examining. Tom Watson will be under enormous pressure to pick Tiger for the Ryder Cup Team, because if he excludes him Tom will become the most hated man in America. Tiger needs to withdraw himself from selection, and make life easier for Tom.
