JOHNS CREEK, Ga. -- If form follows this week, the player hoisting the Wanamaker Trophy on Sunday as winner of the PGA Championship will hail from South Africa or Europe -- specifically, perhaps, the U.K. -- and bring more fame and fortune to a former European Tour pro who started his business with a handshake.
Major championship winners Charl Schwartzel, Rory McIlroy and Darren Clarke are all represented by Andrew "Chubby" Chandler, an Englishman who runs International Sports Marketing and, despite his outgoing and gregarious nature, is somewhat sheepish about talk of one of his clients completing the "Chubby Slam."
"I get embarrassed about it, to be fair," Chandler said. "It's an unbelievable situation, winning. But my name's Andrew, and nobody'd ever call it the Andrew Slam. It's just because I've got a name like Chubby, isn't it? It's something for the media to get their teeth into. I just wonder whether the guys get fed up with it, too."
Well, not really.
McIlroy, told that Chandler said he was embarrassed by the whole thing, elicited plenty of laughter when he said: "No he's not."
"To be honest, we're having a lot of fun about it," McIlroy said. "I think it's funny. I don't know who came up with the name the Chubby Slam, but it's pretty funny and it would be great if it happened."
Those in the ISM stable seem to take pleasure in their collective success and no doubt would love to add to the run this week at Atlanta Athletic Club, where the 93rd PGA Championship begins Thursday.
Going back to the 2010 British Open at St. Andrews, where South African Louis Oosthuizen won the title, Chandler's clients have won four of the past five major titles, with only Martin Kaymer at last year's PGA breaking the streak.
"Now and again you sit down and think what's going to happen next," said Chandler, 58. "We even have a racehorse at home that keeps winning, as well. There's a lot of thought that goes into the preparation of the guys now. It's gone from being sort of a party outfit to being very detailed compared to maybe other teams.
"I think Lee Westwood's physio [fitness] has an awful lot to do with that. He's a very structured person and he's made us realize how much we have to get detail into their lives, which has improved everything."
Westwood, ranked No. 2 in the world, is one of seven ISM players ranked among the top 50 in the world, including Masters champion Schwartzel, U.S. Open champion McIlroy and British Open winner Clarke.
The others of the 11 in the PGA field are South Africans Oosthuizen, Ernie Els and Thomas Aiken; Englishmen David Horsey and Simon Dyson, who recently won the Irish Open; Sweden's Fredrik Andersson Hed; and France's Gregory Bourdy.
Clarke was the first to sign on more than 20 years ago when Chandler was winding up his own golf career. They had a handshake deal that continues today, and it was Chandler who -- on the eve of the Open last month, when nobody was talking about Clarke -- fancied his chances.
"He's a proper links player," Chandler said, referring to Clarke's ability to navigate his way around Royal St. George's. "He plays it on the ground more than anybody."
As for this week, Chandler very much likes the chances of Westwood and McIlroy.
"They both obviously had great preparation last week," Chandler said. "And you can see from Lee's body. He's been in the gym for three weeks really working hard. It turns out he carries himself differently when he's been working that hard. So he's in great shape. And Rory cruised through the Irish Open and built up a bit last week, and I detect that he's going to be absolutely ready on Thursday."
Westwood, 38, certainly seems a prime candidate to break through for his first major as he has watched others around him do it. He reached No. 1 in the world for the first time last year, won twice in Asia after the Masters, lost in a playoff to Luke Donald at the European Tour's BMW Championship and was tied for third at the U.S. Open.
He did miss the cut at the British Open but was tied for ninth last week at the Bridgestone. "My game is in really good shape," he said.
As for the Chubby Slam, Westwood chose to poke fun at his friend and manager.
"I'm not impressed with his preparation," Westwood deadpanned. "I've seen him drinking a bit; he's not been in the gym, haven't seen him on the range yet. I wouldn't hold out much hope for him. He gets a bit flat at the back and bounces it off his shoulder occasionally.
"He doesn't function well in the heat. He drinks a lot, but not water, unless you count tonic water."
Chandler sat in the back of the room, chuckling. All is good right now, especially as it relates to his group of golfers, who seem to be enjoying giving the big man some stick as much as hauling home all the hardware.
But it's more than just all laughs.
"I don't think you can call four major champions in the same year a coincidence," McIlroy said. "The whole ISM family, we're all very comfortable with each other. We've seen one another win majors, starting with Louis last year and then Charl and myself, Darren. We probably motivate one another.
"If one of Chubby's guys were to win this week, it would be a great achievement for the company and personally for Chubby. I'm trying my best to complete the Chubby Slam, and I'm sure a lot of other guys are, as well."
