All Lucas Glover needed was a new attitude, a new set of a clubs and a relaxed atmosphere.

At Port Royal yesterday he had all of those and combined they turned a struggling Tour pro into the champion of champions.

And a year that began with a break has ended with the US Open winner storming to a five-shot victory at the PGA Grand Slam.

Glover shot a second-round 66 yesterday to finish on 11-under, well ahead of Angel Cabrera who snatched second place from Stewart Cink (five-under) on the final hole.

Once again Glover's putter played a large part in his success, just as it has since he changed it at the beginning of the year.

"To be honest I didn't do much practising (before this week), and that might have helped," said Glover.

"The year I've had on the greens after changing to this Nike putter, you know, it's been more consistent, but I've always been up-and-down with the putter.

"This putter, and what I've been working on, seem to . . . keep me a little more consistent.

"I made a couple of long ones on Tuesday, and I didn't miss – I didn't miss anything I felt I should have made today (Wednesday). So I had a pretty good two days on the greens."

The new irons, howeve,r were broken out for this week, and what a difference they made.

"I always play my best golf when I'm relaxed, and it's taken me a while to realise that," said Glover. "But you know, to add to that about having a fun week instead of grinding so hard, I brought out new irons this week with the new grooves just to try and see how they work, because I wanted a couple of rounds under my belt with this new model. So Nike made a good set and I think I like them.

"I use the Nike VRs, and I knew I would have two events to work with them. I didn't give up the wedges, that would be a little too much because that would be giving up too much of an advantage but I just wanted to see how they reacted and I knew it would be breezy.

"I wanted to see how they reacted with my golf ball and in breezy conditions."

Judging from Glover's scorecard they seem to have worked perfectly, and unlike the previous two years when the Grand Slam went to a play-off, Glover's victory was something of a procession once he had broken away from the rest of the field at the turn.

The American rattled off three consecutive birdies at nine, ten and 11 to turn his eight-under-par tie with Stewart Cink into a two-shot lead.

And when he drained another long putt at 12 to rescue his par, it seemed almost inevitable that Glover would be the one wearing the 'pink jacket', at the end of the day.

Not that the day started out that way as Stewart Cink began with two birdies to tie Glover for the lead at six-under.

Glover then dropped a shot at four when his second shot found the greenside bunker, and Cink birdied five to take the outright lead.

They traded blows until the ninth when Glover again birdied and the pair went into the turn tied at eight-under.

Glover took full command on the back nine however, collecting more birdies while Cink had bogeys at 12 and 13.

Further birdies at 15 and 17 took Glover to 12-under, while Cink's challenge had already died after his tee shot at 15 went into thick rough, and he ended that hole with a double-bogey.

An eagle at 17 sent Cink and Cabrera, who also shot a second round 66, down the last tied for second, but Cink's woes on the back nine continued as he bogeyed 18, while Cabrera's par putt earned him an extra $50,000 for outright second.

Cabrera came close to mounting a challenge of his own but a missed birdie putt from 13 feet at 12 left him on five-under.

Y.E Yang ended the day little better than he started it, finishing one-under for the tournament but for a while looked like he might push Cink and Cabrera close for second.

The Korean's eagle at the shortened par-four fifth took him to four-under in four holes, but he struggled on the back nine and his challenge faded under a barrage of bogeys on the back nine.
