Wall was an early leader at Wentworth
England's Anthony Wall and David Horsey and Spain's Gonzalo Fernandez-Castano share a tie for the lead after the opening round of the PGA Championship.
The trio all shot rounds of 67 to stay one shot ahead of a pack including Ross Fisher and Miguel Angel Jimenez.
Both Englishmen set the early pace having birdied four holes on the back nine, before Fernandez-Castano's late charge at Wentworth.
The Spaniard made birdies on 10, 12 and 17 before making an eagle on the last.
"My iron play was good today," said Wall. "The greens were very good this morning so if you hit good shots, you could be rewarded."
Fernandez-Castano needed over five hours to complete his round, but said: "The course was playing tougher than previous years and that's what made it longer, but if I am going to shoot 67 every day playing five hours 20 minutes, I'll take it."
World number four Henrik Stenson, the highest-ranked player in the field, shot a 78, two weeks after capturing the Players Championship in Florida.
The Swede has a poor record in this event having never finished higher than eighth in eight appearances and he was philosophical about his performance.
"Some like hard courts, some like clay. This is not my surface," he said.
"I find it difficult to pick the shots and to judge how the ball will react."
England's Lee Westwood did not fare much better as he bogeyed four holes on the trot from the 12th before rescuing his round with birdies at the last two holes to card a 77.
"At least I beat Henrik by one," he said. "I just didn't play very well - that can happen here."
But Scotland's Colin Montgomerie, who won the event in 2000, hit a promising 69 along with world number seven Paul Casey and last season's European number one Robert Karlsson.
"One 69 is OK but what I have to do is put another one on the board, then another one," said Ryder Cup captain Montgomerie. "If I can do that, I'll be thrilled.
"I have to set my goals the way they were - to win. I feel capable of it still and it's just a matter of going out and proving it to myself. I haven't been doing that."
Masters champion Angel Cabrera shot a 74, with American John Daly and South Africa's Ernie Els managing one better.
