Jamie Donaldson, attempting to win his first tournament in 249 attempts, had five birdies and an eagle in a 65 to move into a share of second with Soren Kjeldsen of Denmark and Tano Goya of Argentina.
Kjeldsen had six birdies and an eagle in the calmer morning conditions.
Italian teenager Matteo Manassero had birdies on two of his last three holes for a 72.
