Best syntax for derivative

Hi, Suppose I have a function of three variables f[x_, y_, z_]:=Sin[x y z] And I want to construct g[x, y, z] which is the partial derivative of f [] with respect to y. I do f[x_, y_, z_] := Sin[x y z] g[x_, y_, z_] := D[f[x, temp, z], temp] /. temp -> y but I'm sure there is something better. Something along the lines of g = Partial[f, 2] Many thanks in advance. Aaron
