If Keegan Bradley had to sum up the opening round of the PGA Grand Slam it appears “fun” would be the appropriate adjective.It's no wonder the affable American enjoyed himself at Port Royal yesterday, having seized control at the turn with a sizzling front nine to leave him five shots clear.Although he was eventually pegged back by Rory McIlroy, who he finished tied with at four-under par, Bradley still couldn't take the smile off his face.“It was a great day. I got off to a really good start and I kind of slowed down on the back, but actually still played very well,” said Bradley, who won the PGA Championship in August. “The two putts I missed I thought could have gone in personally, but it was still a lot of fun.“But you know, it's a lot of fun to be out there, have the crowds behind you and it's a real different experience for me. I've never played in an atmosphere like this. It's really, really fun. I've really enjoyed my time so far.”Bradley recovered from bogieing the first hole to make a red-hot start highlighted by two eagles in his first seven holes.He described his stunning six-irons onto the green to set tap-in eagle putts at the second and seventh as two of his best shots of the year.“Yeah, I got off to a pretty scary start. I made probably about a 20-footer for bogey on one and then on two, I hit a really great six iron to that pin, that back left pin, basically a tap-in and on my second one, I had another six iron right at it,” said Bradley.“It was really two of the best shots I've hit all year really, right at the pin the whole time.”The 25-year-old, one of only three golfers to win on their major debut, believed Port Royal suited his style of play with it reminding him of some of the courses he plays in Florida.“It's a good course for people who can hit it out there and hit it high. You can fly a lot of the bunkers. It's just a good course,” he said.“I play a lot of these courses, courses like this in Florida, same grass, Bermuda. It seems to fit my eye. Seems to fit Rory's eye, too. He hit a lot of long drivers out there that were really, really impressive.”It was a contrasting day for Charl Schwartzel, who at one under par was sitting pretty and confident of closing the gap on Bradley, then five shots ahead.But on the 12th cracks started appearing in the Masters winner's short game as he suffered three successive bogies to leave a dent in his scorecard.That dent then become a severe one with the wheels really coming off the 16th where he took a triple bogey after plonking his tee shot into the water.The final two holes were marginally better for the 27-year-old, who made no attempt to hide his frustration at being unable to marry his promising start with a strong finish.“(It's) disappointing. I thought I actually played really well up until 12. I hardly missed a shot,” he said.“I didn't make any putts on the greens, and yeah, then I three-putted 12 and missed a short one on 13 and 14. And then another three-putt on 16. That was frustrating. I'm pretty disappointed. I thought I played much better.“(As for hole) 16, I mean, Rory hit a six iron and it stayed pretty straight. And that's what I thought; I thought the wind was just dead straight from behind.“I hit a good five iron and it started where I wanted to, and it just went left. I don't know, the wind sort of swirled a little bit in there and took the ball left and hit the slope.“It wasn't actually a bad shot. The problem is that you get penalised by hitting off the tee again.“That's the second time around I hit the same shot that finished on the green and I just probably just rushed those putts and ended up three-putting where I shouldn't have.”On the 17th the heavens opened, rendering Port Royal a lot tougher to negotiate with a loose chip shot costing Schwartzel a chance of a birdie.However, he refused to blame the driving wind and rain for his disappointing finish, believing the “damage had already been done” by then.“We just got a bit of rain coming in the last two holes . . . you could see it coming over the ocean, and we tried to speed up to see if we could finish before it came, but that was pretty severe rain,” said Schwartzel, who only joined the PGA Tour at the start of this year.“I think if it carried on raining like that for another half an hour or so, it probably could have flooded the course.“But you know, my damage was done before that.”
