Home favourite Sergio Garcia shared the midway lead of the Madrid Masters after posting a second-round score of 67 on Friday.

He was joined at the top of the leaderboard by Scotland's David Drysdale, who followed his opening-round 66 with a 65 to join Garcia on 13-under-par total of 131.

The Spaniard learned of golf's successful application to become an Olympic sport in 2016 during his round at Centro Nacional and afterwards he voiced his desire to play in the next three Olympic Games.

"If I stay in shape I probably have three chances," he said.

"I'm thrilled and excited about the possibility. There's still a long way to go, but I'm going to try to stay healthy.

"This is a very special day. We've been fighting for a year now to get it in and it feels good. It's going to be an amazing experience for all of us."

Drysdale, 34, finished his round with an eagle - as Garcia had on the opening day - after rolling in a putt from 30 feet on the 18th.

"The goal has been to give myself a few opportunities and see what happens," he said. "The more experience you gain, the more relaxed you feel."

Three players trail the leading pair by a shot, with England's Ross McGowan, Irishman Gary Murphy and Emanuele Canonica of Italy all finishing day two on 12-under.

McGowan spurned a chance to take the lead when he picked up a double-bogey six after four-putting the 16th, but finished with a 10-foot eagle putt to keep himself firmly in contention going into the weekend.

"That's two of the best ball-striking days I've had," he said.

"My game is as good as it's ever been and hopefully it will keep improving."

Overnight leader Manuel Quiros of Spain followed up his stunning opening-round 62 with a one-over-par 73 that saw him sink to 10th on the leaderboard, while Spanish veteran Jose-Maria Olazabal and England's Luke Donald narrowly made the cut.

Olazabal's round of 65 was one of the best of the day, but his playing partner Darren Clarke crashed out after producing a round of 76.
