Ayr go into their third round match of the British and Irish Cup having won the only two matches they have played so far in 2010 but more significantly, they have a win in the B & I Cup under their belts.
“The win over Rotherham Titans at Millbrae included probably the best first half performance since I have been at the club” said coach Kenny Murray.
He added “this tournament challenges the players and coaches in all aspects of the game, especially in defence and the physicality of the game.
We proved against Rotherham that we could compete at this level and a win against Birmingham and in our home match against Pontypridd would set up a great finale against Cardiff”.
The starting line up will include all five Ayr players who were involved in last Friday's memorable win at Netherdale, when the Scottish Club International side beat the French.
That outing will have fuelled the Famous Five, and the rest of the team, with a desire to taste further cross border success which they first experienced against Rotherham.
Pat MacArthur and Ed Kalman from the Glasgow Warriors ranks will be in the squad and coach Murray has made the intriguing switch of selecting the multi-talented Jamie Murray at 10.
This will see Frazier Climo move to center in place of the unavailable Mark Stewart.
Birmingham have not had their sorrows to seek this term but coach Murray will have his squad fired up to face a side who will be desperate to salvage something from a miserable season.
They are currently re-building with a view to winning the end of season play offs to ensure that they remain in the Championship.
The match kicks off at 4pm at Millbrae which, at the time of writing, was playable but should weather dictate otherwise, alternative arrangements will be made to play the game at a suitable venue.
