This is how I have the rack mounted on my old road bike. However, not all racks haev holes int he centre of the deck to make this possible. If you have a rack with three sets of holes (one on each side and one in the centre) then it will work. If you have one of the racks that is entirely constructed of tubes with no 'deck' on top then it likely will not work. P-clamps are the answer then.
