Playing partners Rory and G-Mac must park management split

Rory McIlroy’s partnership with fellow US Open winner and long-time friend Graeme McDowell could be tested over the opening two rounds of this week’s BMW PGA Championship at Wentworth.

McDowell surprisingly lifted the lid last week in Bulgaria on McIlroy’s decision to sever a five-year management deal with Horizon Sports Management.

However, neither Horizon nor the double Major winner has issued a formal statement confirming split.
