The PGA Championship: Day 1 August 11 2011 By Helen Ross, PGATOUR.COM JOHNS CREEK, Ga. Tiger Wood was grim-faced as he faced reporters after shooting a 77 on Thursday at the Atlanta Athletic Club. The round of 7 over had started with such promise as Woods birdied three of his first six holes, briefly holding a share of the lead. When he signed his scorecard, though, Woods had posted his highest opening round ever in a major championship. Unlike a week ago at the World Golf Championships-Bridgestone Invitational, where Woods returned to competition after a three-month layoff and focused on the positives, the former world No. 1 appeared extremely frustrated. "I' not down," Woods said. "I' really angry right now. So there's a lot of words I could use beyond that." Woods?round started to disintegrate on the final four holes of the back nine, which he had said earlier in the week was the most difficult closing lineup he could remember. He made double on Nos. 15 and 18 and bogey on the 16th. "It was a tough stretch," Woods said in understatement. Woods?troubles continued on the front nine as he bogeyed three of his first four holes, made one birdie at the fifth, doubled No. 6 and bogeyed the ninth. Only one other time had Woods recorded scores of double bogey or higher on three holes during a single round. That was at the 2007 Bay Hill Invitational where he had two double bogeys and a triple bogey. Asked whether he was more frustrated by the score he shot or where he stood in the process of rebuilding his swing with Sean Foley, Woods didn't hesitate. "Both. Both," Woods said. "Because I was 3 under early, and I said, you know what, every shot I hit up to that point were all mechanical thoughts, I put the club in a certain position, and I was doing that and I said, you know what, I'm feeling good. Let's just let it go. And it cost me the whole round." Woods said he had a "laundry list" of things to work on before he teed off on Friday. He realized he got away from a more mechanical approach, concentrating on the things he's been working on with Foley, and old habits began creeping into his swing as the day progressed. 'I thought I was playing well enough that I don't have to do that,?Woods said. 'I can just go out there and play and let it go and just play by feel and see the shot, hit the shot, feel it and I'm not at that point yet. My motor pattern is getting there, and I start fighting it, and I couldn't get it back. Obviously it's tough.' Consequently, Woods is in danger of missing the cut at a major championship for only the fourth time in his career. 'I've been in this process before: I've been through it with Butch; I've been through it with Hank; and now I've been through it with Sean.,Woods said. "I just thought, this is a major, and you peak for these events. And once you get to a major championship, you just let it fly, let it go. "And I did and it cost me." Woods could now find himself on the sidelines for the next six weeks. He started the week ranked No. 129 in the FedExCup standings" and only the top 125 at the end of next week Wyndham Championship advance to the PGA TOUR Playoffs for the FedExCup. Woods said last week he had family obligations and would not compete in Greensboro. So based on last year's point totals, Woods likely needs to finish 14th or better in order to be among the top 125 at the end of the Wyndham Championship.
