Paul Waring has said that he knows the job is not done despite taking a two-shot lead ahead of the final round of the Portugal Masters.

Waring birdied four holes on the back nine in Faro to convert his joint overnight lead into a outright one. If he can hold off the competition tomorrow, then he will register his first win on the European Tour.

"I started a bit poorly and didn't quite hit it close enough but holed some nice putts towards the end of the day. I feel pretty good, two ahead, so we will see what happens tomorrow," Europeantour.com quotes him as saying.

Asked if he is ready to claim a maiden victory on Sunday, Waring added: "I can't really say. You don't know what's going to happen with the other lads, what anyone else is going to score. You can't control those sorts of things.

"All I can do is control what I can control and add them up at the end of the day and see what happens."

The 28-year-old enjoyed his first top-five finish on the Tour at the Open de Espana in April and has had three more top-10s since.
