Graeme McDowell hoping his maths teacher’s course design boosts Irish Open chances

Graeme McDowell hopes the ultimate in home comforts can help him find the missing piece of the jigsaw in the £5.4million Dubai Duty Free Irish Open at Portstewart.

McDowell was born just a few miles away in Portrush and is staying in his parents' home this week, a house he bought for them after winning his first European Tour title in 2002.
