Golf-Garcia pulls out of Wentworth showpiece with knee injury

VIRGINIA WATER, England, May 22 (Reuters) - World number seven Sergio Garcia has pulled out of the BMW PGA Championship because of a knee injury, organisers said on Thursday. The 34-year-old Spaniard announced his withdrawal after opening his campaign at the European Tour's flagship event with a one-over-par 73. Garcia's playing partners fared better. German Martin Kaymer posted a 68 and fellow Spaniard Miguel Angel Jimenez shot a 72. Denmark's Thomas Bjorn was leading the way on 62, the lowest score in relation to par in the history of the 60-year-old event. (Reporting by Tony Jimenez, Editing by Ed Osmond)
