SOUTHAMPTON PARISH, Bermuda, October 20, 2009 (AFP) - US Open champion Lucas Glover seized control on the first day of the PGA Grand Slam of Golf firing a course record six-under 65 Tuesday.

Glover has a two-stroke lead over fellow American and British Open champion Stewart Cink at the Port Royal Golf Club course.

Glover's superb round included two long putts on the fourth and seventeenth holes.

The Grand Slam event comprises the four major championship winners of the year.

The $1.35-million tournament wraps up Wednesday with 18 holes.

Stewart shot four-under 67, Masters winner Angel Cabrera had a one-under 70 for third place and giant-killer Yang Yong-Eun, who beat Tiger Woods in the PGA Championship, is fourth following an even-par 71.

Glover's first long birdie, and second birdie of the round, came on the fourth hole.

"That was a hit-and-hope and it just went in," said Glover. "It had to be 50, 60 feet."

One of the few stumbles of the day came on the par-three No. 16 where he made bogey to drop to four-under for the day.

"It's a shame because it's so pretty but it's so hard," said Glover of 16. "I think we had a little four-, five-minute break there just taking it all in. We had a good time on that tee and we all hit pretty bad shots."

Glover bounced back on No. 17 by rolling in a 30-foot eagle putt then parred the final hole.

"Stewart and I were joking, we both played well today, where was that last week, that kind of thing," said Glover. "I didn't hole much at The Presidents Cup, so pretty excited to see some go in."
