A goal from David Cawley was not enough to overturn Drogheda United's 2-0 first leg advantage, as the Drogs progressed to the Setanta Sports Cup final at Sligo's expense
The hosts searched for a way back into the tie from the outset, with Premier Division top scorer Anthony Elding forcing goalkeeper Gabriel Sava into an early save. The keeper almost gifted Sligo a simple goal on the quarter hour mark, but Brian Gannon got back to block Aaron Greene's goalbound effort.
Sligo took the lead after 30 minutes with David Cawley finding the net after some fine interplay with Elding, giving them hope of progress. Just before half-time, Gavin Brennan's free-kick found Alan Byrne at the back post, but the defender could not direct his effort on target.
Drogheda thought they had equalised just after the restart, but Paul O'Connor's long-range effort bounced down off the crossbar, and the referee waved play on despite loud claims from the visitors. A great ball from Lee Lynch found Elding in a great position a few minutes early, but the striker got under the ball and it sailed over the bar.
Elding went closer again with a header as Sligo searched for the all-important second goal, as the hosts pushed everyone forward in the game's latter stages. Danny Ventre and Cawley both had late chances for the Bit o' Red, but Drogheda defended well to hold on for the aggregate victory.
Drogheda are the competition's most successful side, having lifted the trophy in 2006 and 2007, and will face Shamrock Rovers in the final on May 11th.
