Fulke fired a 4-under-par 68 on Friday to move to 9-under-par through 36 holes at Montecastillo, one shot clear of Spaniard Jose Maria Olazabal. Northern Irishman Darren Clarke is two strokes back, tied at 7-under with Swede Fredrik Jacobson and Aussie Stephen Leaney. Scot Colin Montgomerie stands in sixth place alone at 6-under after shooting his second-consecutive round of 69.
Fulke, who began the day in Jerez, Spain, tied for the top spot with Olazabal, birdied three of his first five holes in the second round to take sole possession of the lead. The 2000 Scottish PGA champion went out in 33 and came home in 35. Through two rounds, the Swede has carded ten birdies to just one bogey.
Including his final round 62 at last week's Italian Open, Fulke has played his last 54 holes in 19-under-par. He'll have to continue that torrid pace if he wants to fend off his pursuers.
'There are some big names just behind and it's up to me to keep in front of them,' said Fulke. 'Overall, I haven't made any mistakes and that was a pretty solid round of golf.'
Fulke will be again paired with Olazabal in the third round. Friday, the Spaniard carded a 3-under-par 69, though he did so without birding any of the four par-5s.
'I was disappointed about that,' the 2000 Benson & Hedges International Open champion said. 'I missed three drivers and couldn't make birdies, which is a pity. It could have been a much better round and it leaves a bad taste.'
The shot of the day belonged to Montgomerie. Monty aced the par-3 14th with a 6-iron from 174 yards. The hole-in-one, his 6th on Tour, help keep him in contention entering the weekend.
'It was an eagle, 2-under-par, and that was the key to the day,' Montgomerie said. 'It wasn't a fluke because you're meant to do it, but you need a bit of luck. One shot like that can chance you body language. This might be my week. You never know.'
