Webb Simpson is the 1st round leader at the WGC Bridgestone Invitational at Firestone Country Club, South Course. Webb Simpson / Getty Images Webb had a first round of -6 under par 64 to lead the WGC Bridgestone Invitational at Firestone by just one shot. Webb said he had profited from his caddie Paul Tesori's knowledge of the Firestone course; "Well, I knew it all through my caddie Paul Tesori, who's been here so many years, I just kind of had to listen to him. It's hard for us players to listen to our caddies, but he basically showed me where to go yesterday and told me where to hit it, where the lines were, what clubs to hit. I didn't feel like it was my first time because he has so much experience here." Henrik Stenson is in second place at -5 under par, 65 to occupy that position on his own. Henrik was upset about his bogey on the last hole, and the fact his new shoes caused a blister and he swapped back to his old pair; "I wish I didn't bogey the last hole, it's one area I've got to get better at. When I'm between clubs, hitting more club and swinging easy is where I've been struggling. You know, there's always something to work on. I feel like I've let a couple of tournaments go that maybe I should have closed out. They might not match the outfit perfectly, but it felt like I had socks on compared to the other ones." You notice there was no mention of the shoe maker, I guess there was too much money involved. There are four players tied in fourth spot at -4 under par, they are; Ryan Moore, Chris Wood, Keegan Bradley and Tiger Woods. Tiger reported that he had really concentrated on the wind factor and how he has taken advantage of the Firestone course in the past; "I hit a lot of good shots. I had a really good feel for the distance today, and Joey and I really read the wind right today. We changed a lot of shots out there, and we both had a really good handle on what we were doing feel-wise with the wind. Luckily, over the years I've taken advantage of it. I have played well and I've scored well, and I've won my share of tournaments here." Keegan is trying to ignore the pressure to do something crazy; " It's business as usual, I just want to not put too much pressure on myself to do anything crazy. I know this golf course fits me, so to let the course come to me is big here." Phil Mickelson, coming off his fantastic victory at the British Open two weeks ago, unfortunately seemed to struggled with his concentration and came in with a +2 over par 72. "Tonight I'll get a little bit more rest and try not to do too much and see if I can come out tomorrow a little bit more focused." Rory McIlroy will defend his title at the PGA next week, I don't think he has a hope, Rory has not won a tournament since the PGA, in a year of amazing up and down swings that included a Ryder Cup victory and a whole series of disappointments. Rory shot an even par round of 70. He said he was just throwing shots away; "I just threw a few shots away around the greens. You know, you start to save shots there and all of a sudden you're -3, -4 or 5-under par."
