Rory McIlroy is quitting Dublin-based sports agency, confirms Ryder Cup team-mate Graeme McDowell However, McDowell, who has been with the Dublin-based Horizon agency for four years, informed reporters at the Volvo World Matchplay in Bulgaria that there had been a parting of the ways, but that it was "amicable." It is believed McIlroy is taking at least one member of the Horizon staff with him, as he prepares to end the contract with the agency and go on his own. Conor Ridge, the Horizon chief executive, on Friday refused to comment, but it is likely that is because of the legal issues involved. Reports in Ireland and the US suggest his father, Gerry, will take a prominent role in his new management team. A media manager may also be required. McIlroy has spoken for his admiration of Roger Federer and it is surely no coincidence that the tennis superstar has recently put together his own backroom. McIlroy's Ryder Cup team-mate Ian Poulter is determined to bounce back at Wentworth after going out of the Volvo Matchplay at the earliest opportunity on Friday, following missed cuts at both the Masters and the Players Championship. "I'm disgusted," he said, after losing to South Africa's Thomas Aiken on the 18th. I'm going to find the tallest tree with the shortest rope. I'm p----- off and will stay p----- off for a couple of hours and then get to England and win at Wentworth. McDowell is now the favourite after accounting for Scotland's Stephen Gallacher 4&2. Last year's beaten finalist plays American Bo van Pelt to go through to this afternoon's quarter-finals. Scotland are still represented as Scott Jamieson takes on the Chilean Felipe Aguilar, while Chris Wood will fly the England flag against South Africa's Richard Sterne. Next Tuesday, the R&A and United States Golf Association will announce their decision on whether to ban "anchoring." The rules change, which will effectively outlaw belly-putting, will come into effect in 2016. The move by the two governing bodies has been heavily criticised by the PGA Tour.
