After a cagey start to the game the first chance went to the home side in the 12th minute when Danny Hylton shot over the top from range. Carlisle at a corner seven minutes later then seeing James Berrett's delivery headed goalwards by Stephen O'Halloran, only for a mixture of Jamie Collins and Peter Vincenti to manage to hack the ball away from the Aldershot goal-line.
Francois Zoko then hit an effort over Ross Worner's crossbar from distance for Carlisle in a short spell of pressure in which both Tom Taiwo and James Berrett had shots blocked from outside the Town penalty area, and Craig Curran fired wide from a low Andy Welsh cross. The Blues then paying for those missed half-chances right on the stroke of half-time when a Luke Guttridge pass set up Michael Rankine for a well-hit strike from 18 yards out across Adam Collin and into the far corner of the Cumbrian net.
Carlisle then missed a good chance to equalise on 47 minutes when a Jon-Paul McGovern pass played in Zoko, the Ivorian though scuffing a horrible shot towards the corner flag from close range. United's Matt Robson then went into the book for a poor tackle on Jermaine McGlashan seven minutes later before shortly afterwards the home side missed a great chance to make it 2-0 when a clean through McGlashan smacked a low shot inches past Collin's right-hand post, that opportunity coming moments after Darren Jones had headed wide from a Collins free-kick.
Guttridge then went into the book for what almost looked a red card elbow to the head of O'Halloran before the Shots all but wrapped up the tie with a second goal of the game on 75 minutes, Anthony Straker sticking in a low cross from the left which United centre-half Danny Livesey was only able to deflect straight into his own net. Carlisle from that point on not even having any real half-chances to get back into the match and force extra-time with both James Berrett and Curran seeing yellow from referee James Linington before the final whistle.
