Garcia and Kaymer among Doha leaders

Sergio Garcia and Martin Kaymer, Ryder Cup team-mates who both ended last year lifting a trophy, are part of a four-way tie for the halfway lead at the Commercial Bank Qatar Masters.

But Paul Lawrie, another of Europe’s heroes in Chicago, saw his defence of the title come to a premature end after a four-putt double bogey on the 15th hole. He missed the cut by a single stroke.
