What was the world's most successful management company at this year's majors?
What about ISM, who look after the affairs of Lee Westwood and Ernie Els? Not them either.
Take a bow Dublin based Horizon Sports Management, which poached Ross Fisher from IMG at the start of this year and Graeme McDowell from ISM two years ago.
Of the 12 players to make the cut in all four majors this year, Fisher and McDowell finished first and tied second respectively.
Fisher was T-30th in the Masters, 5th in the US Open, T-13th in the Open and T-19th in the US PGA last week. As for McDowell, he tied for second with Henrik Stenson (represented by Johan Elliot at Stockholm based Sportyard), the Ulsterman finished T-17 at Augusta, T-18 at Bethpage, T-34 at the Open and T-10 at Hazeltine.
CBS Sports' Steve Elling compiled the 2009 Grand Slam leaderboard which shows Fisher pipping McDowell and Stenson by a shot with a cumulative +2 total. Lee Westwood was fourth and Rory McIlroy fifth.
Amazingly, not one of that quintet them is currently a member of the PGA Tour and only four Americans made the list.
