Dublin have been crowned the Bord Gais Energy Leinster Under-21 hurling champions.

A superb second-half performance saw the Dubs defeat Offaly by 2-15 to 1-10 in tonight's provincial final in Tullamore.

Sean Treacy got both of the Dublin goals shortly after the break as they reeled in Offaly and then overtook them.
