McDowell primed for daunting defence

Graeme McDowell believes he faces a much sterner challenge this year as he sets out to defend his Ballantines Championship title at the Pinx Golf Club on Jeju Island.

As well as a tougher field, including the likes of three-time major winner Ernie Els, world number nine Henrik Stenson and Lee Westwood, McDowell believes the change in timing of the tournament will also play a decisive role.
