A bogey at the first hole of the final round by Ricky Barnes means he and fellow American Lucas Glover will hold a five-shot lead over the chasing pack when play at the US Open resumes on Monday morning (US time). The fourth round of the weather-delayed Open finally got under way late on Sunday but Barnes, who briefly led by six at one stage earlier in the day, made a mess of the opening hole and then hooked his tee shot into the hay at the next before the hooter sounded to end play. The tour rookie opted to mark his ball rather than hack it out with Glover nicely positioned in the fairway after safely parring the first, and will do well to make bogey when he returns. The good news for the leaders was that none of their closest pursuers fared much better – the penultimate pairing of David Duval and Ross Fisher both bogeyed the first with the latter facing a testing par putt at the second hole first thing in the morning. The Australian challenge is now a distant memory, with Adam Scott and Michael Sim – playing in a twosome with Tiger Woods – at four-over and a distant 11 shots off Barnes and Glover&aposs pace, while 2006 US Open winner Geoff Ogilvy is five strokes further back. However, Phil Mickelson and Hunter Mahan remain on two-under-par having completed two holes – the former seeing two birdie attempts slip agonisingly by. Only 11 players were under-par when the final round got under way but that was reduced to seven in the two hours or so of play the fading light allowed. Ominously, Woods got it to even-par for the tournament – picking up a shot with a birdie at the seventh, playing on after the hooter when he drilled a four iron to eight feet and coolly knocked in the putt in near-darkness. Woods had failed to get his round going after dropping a shot at the first, and although he birdied the next he saw two good chances slip by before the final blow that he hopes will have sent a message to those further up the leaderboard. The defending champion could be thinking a score of three- or four-under may be good enough for a play-off, and if his putter gets hot for the first time this week he may yet land a 15th major title.
