Graeme McDowell encouraged by recent form

Northern Ireland's Graeme McDowell says he feels he is getting back to his best as he prepares for the US PGA Championship at Whistling Straits.

The 2010 US Open champion felt there were a lot of positives to take from his performance at last week's WGC-Bridgestone Invitational and said he was starting to enjoy the game again.

And McDowell, 36, added he was expecting massive crowds at the last major of the year to witness world number one Rory McIlroy's return from injury.
