Peter has a one shot advantage after his opening round of -5 under par 65, at the HP Byron Nelson Championship. He joined the PGA Tour last year and is looking for his first win, he was suffering from travelling and a sore back;

"Always nice to get off to a fast start. I still have quite a bit of pain, but I really wanted to play this week. "Heading over to Europe the next two weeks. We have a big tournament, Wentworth, and then my national open back in Sweden the week after that. This is a bit of a test."

David Duval is in the group of three players at -4 under par, although he very nearly did not play due to an injury problem, his right elbow making it hard to swing;

"I'm just glad I chose to tee off today because I was seriously considering not to, can't use my right arm. I'm tickled pink it feels as good as it does right now. I'm not getting to play a whole lot right now and it would have been a hard thing to swallow not to be able to tee off."

"A little disadvantage when you don't get to play consistently, but I have the utmost confidence in what I'm trying to do right now, and I feel like I can succeed even with that sporadic schedule."

Marc Lieshman and Tim Wilkinson are the two players tied with David at -4 under par.

Last weeks winner Martin Kaymer is a whole bunch of players at -3 under par, while last weeks adversary Jordan Spieth could only manage an opening round of even par 70.

Jordan was upset at his performance;

"I kept myself in it, it was a difficult day. I was upset today, I get upset out here when things aren't going my way because I want them to so bad. Michael did a great job of calming me down, putting things in perspective, and we got a couple birdies to finish to get back in it."

"I'm really happy with the way I'm keeping myself in it around the greens, I feel very confident and comfortable around the greens. Once I hit a few fairways, my iron play will be there and hopefully get back on track and make a run."

There is a lot of golf still to play here, and I am sure that Martin Kaymer, given his current form, will be in contention come Sunday.
