Sullivan shares lead in Qatar
Former Ryder Cup player Andy Sullivan credited a renewed sense of focus after claiming a share of the halfway lead in the Commercial Bank Qatar Masters.
Sullivan carded a second consecutive 66 at Education City Club in Doha to reach 10 under, a feat matched late in the day by Spain's Jorge Campillo. England's Oliver Fisher is a shot off the pace alongside France's Romain Langasque, Holland's Joost Luiten and the Swedish pair of Alexander Bjork and Marcus Kinhult.
Sullivan said: "I've got it under lock at the moment. I feel like I am in control of myself, which is the most important thing for me.
"I really felt like I took my time a little bit more on shots. When I have been doing well before I generally rush the shot, maybe try to hit it a bit quickly, so I have been trying to take my time a little bit more and be a bit more composed.
"I feel like I have grown up a little bit now. I think that having a laugh on the golf course is all well and good and I still enjoy it, but for me I have really had to knuckle down the past two days to keep myself in check because there are times when I find myself wandering."
