Rafael Cabrera-Bello again made the most of his chance to impress playing partner and Ryder Cup captain Paul McGinley by firing a seven-under-par 65 to move two shots clear after the second round at the Qatar Masters.
The Spaniard, who also led last week's Abu Dhabi Championship after two rounds before finishing fourth, hit eight birdies and covered the back nine in 31 to move to 13 under for the tournament.
"This feels like home, I like playing in short sleeves a lot with a little breeze, I like seeing palm trees, I like seeing the sun around the courses," the Spaniard told Al Jazeera.
South African George Coetzee, the overnight leader, slipped to second after shooting 69 earlier in the day.
British duo Steve Webster and Matthew Baldwin and Sweden's Johan Carlsson are a further shot adrift on 10-under.
