Langer, a runner-up in this event four times though never a winner, came out like a man possessed. A remarkable birdie run of seven started on his ninth hole and lasted through the sixth en route to a back-nine 30.
He added another birdie earlier in the round, on his sixth hole, and posted no bogeys for a 64, two off the course record.
Celebrating his 45th birthday on Tuesday, Langer is looking for his first win of the season following a pair of victories in 2001.
'It would be nice to win this one but lets not jump too far ahead, Langer said. It is only the first day and there are a lot of guys just one or two shots behind me. But it is nice to be in this position and hope my game will continue the way I played today.
Bland caught fire early Thursday on the courses back nine, his front nine, carding birdies on six of his first nine holes for his 65. He, too, was without a bogey on the day.
'I have been playing well for a while now and it is nice to get out of the blocks a little earlier and put a number up, said Bland.
Poulter, also without a bogey, had a birdie to start and end his round and sandwiched in another five to close with a 65.
Coles' scorecard looked quite a bit different, though, as he, too, shot 67 for a share of second place. His last six holes saw him post two birdies, two pars, a bogey and an eagle. Another eagle at the 11th and a couple more birdies on the front side closed out his scoring.
American John Daly, the defending champion, did not dissappoint in terms of drama. After getting to 4-under after nine, Daly then went bogey, bogey, birdie, double, bogey, birdie, par to finish his day at 2-under.
True to his brillance, and his inconsistency, Daly played one stretch of 11 straight holes without making a par, which included six birdies, four bogeys and a double bogey.
South African Trevor Immelman stood two strokes off the pace with a 66, and a large group of 11 golfers were three back, in with 67s.
