They came out on top of St Mark's CS 3-0, showing an edge in experience in the final showdown. The Ranelagh school opened the scoring in the 16th minute when Patrick Carey squeezed the ball past Carl Crosbie.
Eliot Simons got the second before half-time, finishing tidily after being set through one-on-one. St Mark's, though, did create a couple of clear-cut chances, the best of which fell to Christopher Delmar but his shot hit the outside of the post.
But Darragh Herlihy completed the scoring midway into the second half to seal victory. Mark's had a few late forays into the Sandford circle, the pick of them seeing Luke Forrester denied by a sprawling Stephen Lavery, but to no avail and Sandford had their first hockey silverware since claiming the senior league in 2000.
