Australia's Brett Rumford is tied for second but Ireland's Paul Dunne is in pole position to claim a second European Tour title after establishing a healthy lead at the halfway stage of the Spanish Open.
Dunne, who held off Rory McIlroy to win the British Masters at Close House in October, carded nine birdies and two bogeys to add a 65 to his opening 66 at the Centro Nacional de Golf.
At 13-under-par Dunne leads by three shots from Spain's Nacho Elvira, England's Callum Shinkwin and Rumford, with world No.4 Jon Rahm a shot further back alongside Scotland's Marc Warren, England's Robert Rock and Sweden's Henric Sturehed.
"It was one of those days, I wasn't really thinking about the score and the score kind of built on itself," Dunne told Sky Sports.
"Turns out all three of us in the group shot seven-under so it was an enjoyable day. The conditions were a lot better and playing early we had better greens than we did yesterday."
Next-best of the Australian contingent was Marcus Fraser, who moved to seven-under following a 66. Jason Norris is one shot back after following his opening-round 67 with a 71.
Jason Scrivener is at five-under tied for 39th while Adam Bland, Nick Cullen and Andrew Dodt failed to make the cut.
