Drysdale was born in
Edinburgh. He turned professional in 1995. He married his childhood sweetheart Victoria in 2004. Drysdale currently competes on the
European Tour, having graduated through
qualifying school for the fourth time at the end of 2008. He had previously qualified for the elite tour in 2001, 2006 and 2007 through q-school, in addition to graduating directly from the
Challenge Tour in 2004, when he finished 12th on the end of season rankings, largely thanks to a sudden death playoff victory over
Mattias Eliasson at the
Bouygues Telecom Grand Final. Prior to 2009, Drysdale's best finish on the European Tour had been as runner-up at the 2006
Russian Open. In March 2009, he equalled that when he finished second in the
Open de Andalucia. That result in Spain followed a third place in the
Joburg Open earlier in the season, allowed Drysdale to qualify for the season ending
Dubai World Championship. He finished the season inside the top 50 on the
Race to Dubai, to comfortably retain his card for the 2010 season. In October 2009, he briefly became the highest ranked Scottish golfer in the
Official World Golf Ranking. In the 2012 season on the European Tour, Drysdale's best finishes were a 3rd place in the
Joburg Open, 7th at the
Irish Open, and 10th at the
BMW PGA Championship. He was well inside the top 60 of the European Tour Race to Dubai, finishing 48th. The 2013 season saw Drysdale finish 6th at the
Avantha Masters, and 10th at the
Johnnie Walker Championship at Gleneagles. His final position on the Race to Dubai of 80th was more than good enough to retain his playing rights for the 2014 season. In 2014, a back injury at the start of the season caused Drysdale to pull out of the
Nelson Mandela Championship. He finished 8th at
The Championship at Laguna National in May, his first top-10 of the season. At the
ISPS Handa Perth International in October, he had to finish in the top 7 to retain his European Tour card for 2015. On the last putt on the 18th green, Drysdale holed a 30-foot putt to finish 4th place and secure his card for the following season finishing 102 on the 2014 Race to Dubai. ==Professional wins (3)==
