Surrey, England (My Sportsbook) - Spaniard Gonzalo Fernandez-Castano opened with a five-under 67 Thursday to share the lead after the first round of the BMW PGA Championship.

He was joined in the lead by Englishmen David Horsey and Anthony Wall.

Defending champion Miguel Angel Jimenez posted a four-under 68 and he shares fourth place with Niclas Fasth, Ross Fisher, Barry Lane and Charl Schwartzel.

After Horsey and Wall posted their 67s early, Fernandez-Castano matched them later in the day with a late rally. He traded a bogey for a birdie from the third.

The Spaniard started his climb up the leaderboard on the West Course at Wentworth Club with birdies on eight, 10 and 12. He stumbled to another bogey on the par-four 13th.

Fernandez-Castano chipped in for birdie on the 17th to get within two of the lead. He then eagled the par-five closing hole to grab his share of the lead.

"You had to be patient because it took us five hours and 20 minutes to finish the round. You had to be patient if you wanted to do well," Fernandez-Castano explained. "That chip on the 17th was fantastic. I missed the green short and right with my second, probably the last place you want to be on that hole with that pin position today and how hard the greens are.

"I hit a fantastic chip and that was a birdie, and then a fantastic five-wood on the last to four feet and then holed it. So that's a great feeling to end the day."

Horsey tripped to a bogey on the third, but bounced back with birdies at six and seven. After four straight pars around the turn, Horsey collected his third birdie at the 12th.

The Englishman closed with three consecutive birdies to get to five-under.

"I started off a little bit slow, two three-putts on three and four, four being for par, which was a bit disappointing," Horsey admitted. "I birdied 12, and the last three, so that was a strong finish. The back nine is playing downwind today, so it's a little bit easier than the front nine, but you've still got to shoot the score, so I'm very pleased with how I finished."

Wall notched birdies on the fourth and eighth before stumbling to a bogey on the par-four ninth. He connected on back-to-back birdie efforts from the 11th to move to minus-three. Wall birdied 15 and 17 to finish at minus-five.

"My iron play was good today. The greens were very, very good this morning, so if you hit good shots, you could be rewarded, which was the case," Wall stated. "I'm looking to have a good week. I'm staying at home, nice and relaxed, playing well and off to a good start. There's no reason why we can't have a good week."

World No. 7 Paul Casey opened with a three-under 69. He was joined in ninth place by three-time winner Colin Montgomerie, Robert Karlsson, Soren Kjeldsen, Maarten Lafeber, 2004 champion Scott Drummond, Anthony Kang, Ben Curtis, Alvaro Quiros and Alexander Noren.
