Rafael Cabrera-Bello made the most of an opportunity to impress Ryder Cup captain Paul McGinley as he stormed into the lead in the Commercial Bank Qatar Masters on Thursday.
Cabrera-Bello outscored playing partner McGinley by 12 shots over the first two rounds in Doha, adding a sparkling 65 to his opening 66 to reach 13-under-par.
The 29-year-old Spaniard, who was fourth behind compatriot Pablo Larrazabal in Abu Dhabi last week, carded one bogey and eight birdies, five of the birdies coming in the last seven holes as he covered the back nine in 31.
That gave the former junior Ryder Cup player a two-shot advantage over South African George Coetzee, who had looked like holding onto his overnight lead after shooting a 69 earlier in the day to reach 11-under 133.
English duo Steve Webster and Matthew Baldwin shared third place on 10 under after rounds of 69 and 66 respectively, putting them alongside Sweden's Johan Carlsson, the Challenge Tour graduate firing eight birdies and an eagle in his 65.
Webster could not repeat the fireworks of his opening 65, when he recorded what is believed to be the first ever albatross on the opening hole of a tournament.
But the two-time European Tour winner still managed to chip in for a birdie on his first hole on Thursday and the 39-year-old added five more and three bogeys.
"It was a little bit scrappy today," Webster told Sky Sports. "I missed the green with a lob wedge on the first and chipped in for a birdie which was nice. I played good but didn't give myself enough chances so 69, I'm happy with that."
Webster had holed his second shot to the par-five 10th - his first hole - from 254 yards on Wednesday, and was entertaining thoughts of an amazing repeat when he reached the hole again this morning.
"I had the perfect yardage for my five wood again but just pulled it a bit and hit it to 40ft," Webster added. "It was in my mind again and I thought back-to-back would be nice but it didn't happen.
"I was a bit disappointed how I played today, I warmed up great on the range at 5:30am but I never quite got going on the course. To shoot 69 I have scrambled a little bit."
Webster explained he had worked hard on his putting earlier in the week with coach Damian Taylor, who also works with Larrazabal.
"It would be nice to do the double," Webster added. "We did a lot of work Monday and Tuesday on my putting, probably six hours, and changed the shaft in my putter for a little bit more feel and it's working well this week. If you can make a few putts it makes all the difference out here."
Coetzee, who finished second in Qatar last year when Chris Wood eagled the 72nd hole, said: "I enjoy this place and will be trying to do one better than last year.
"I just had a bit of a wobble on the 11th, my second hole, but otherwise I played pretty nicely. There are some bogeys out there but there's definitely some birdies to recover from."
