England's Justin Rose shot a six-under 64 to share the first round lead at the Texas Open with Germany's Alex Cejka.

They are a stroke clear of the field, with former major winners Justin Leonard and David Duval among a group three shots off the lead.

Rose has not won since 2002 but has been in contention at both the Canadian Open and Lumber Classic this month.

"I'm really just trying to keep giving myself a chance and I know it's going to happen eventually," said Rose.

"Obviously, I have been playing well the last three weeks and I guess my one concern this week is running out of steam and stuff like that, so obviously I'm really happy with my round.

"I could have certainly won coming into this tournament but I haven't had a lot of legitimate chances and, you know, sometimes you need to relearn a few things.

"The exciting thing for me is getting myself into position more and more - the more you knock on the door, the more it's going to open."

Bob Burns, Ted Purdy, Australian David McKenzie and DA Points are the group of four one shot off the pace on 65.

Bernhard Langer is four shots off the lead while Jesper Parnevik is one shot further back after a 69.
