Darren Clarke looking forward to 'fun' US PGA

Ryder Cup captain Darren Clarke is going into the US PGA in a relaxed mood while he discusses the emergence of Shane Lowry and Rory McIlroy's chances at Whistling Straits.

Lowry won the WGC-Bridgestone Invitational at the weekend and will be pushing for a place in Clarke's team to face the USA next year.

Clarke believes world number one McIlroy can bounce back from his ankle injury and secure a fifth major title this week.
