Left-handed Davis worked with respected coach Jay Carter on moving the ball from right to left while Hamilton also fades the ball strongly, although he conceded his mate has got a few yards on him off the tee.
"Sam hits it long so we should be on the par-fives in two shots no matter who tees off. He also hits it straight, although I've probably just put the kibosh on him so you'd better say he hits it wide and short."
Hamilton hoped the win would put them in contention for future national selection.
"Foursomes probably isn't the big prize but any result at national level that puts your name out there has got to be a good one."
In the women's division Auckland's Caryn Khoo (Pakuranga) and Brittney Dryland (Titirangi) won by two shots from Larissa Jane Eruera and Chantelle Cassidy. Khoo, a Srixon Development Member, and Dryland had rounds of 78 and 77 to win the national title.
