Spain:Briton Gary Boyd equalled the Mediterraneo course record of 63 on Saturday to lead the Castello Masters third round by two strokes.
Matteo Manassero, the 17-year-old Italian hoping to become the youngest European Tour winner, shares second place with Sweden`s Christian Nilsson, who produced another miraculous shot to maintain his challenge.
Englishman Boyd, in his rookie year on tour, went eight-under just three hours after his friend and compatriot John Parry had also shot 63 to lie five strokes off the pace.
Now Boyd, on 14-under 199 for the tournament, is determined to match Parry`s recent win in the tour`s Vivendi Cup.
"John`s my room-mate and we`re feeding off each other this year, trying to push each other along," the 24-year-old told reporters.
"But a lot of my friends have won on tour; I`m the only one left. I`m going to be trying to change that."
Manassero holed a 40-foot birdie putt from off the green on the 17th for a 67.
It kept alive his chances of bettering New Zealander Danny Lee`s triumph at the 2009 Johnnie Walker Classic, when Lee was 18.
Manassero felt his driving and putting this week have given him a great opportunity.
"You have to hit the ball straight here, that`s the sort of course I like," Manassero said. "And the greens are pure, you can hole some long putts on them."
Nilsson finished second in last year`s Castellon event behind his compatriot Michael Jonzon.
The Swede preserved his round of 66 in breathtaking fashion on the last, finding the green despite having to play from the base of a dry-stone wall with an advertising hoarding blocking his route.
