The only thing missing from a perfect Saints victory was a 100th goal for the club from Lambert, who put in another impressive display despite failing to score.
"He is a great 'out ball' for us," Davis said. "Obviously he has got a lot more to his game than just holding up the play, but that is an important aspect of his play as well.
"He brings other into the game and allows others to get up the pitch. He did that really well."
