Dundee United are out of the Irn-Bru Cup after losing in a dramatic penalty shoot-out to Alloa.
Matty Smith opened the scoring for the home side in the first half with Alan Trouten equalising for the Wasps in the second 45.
With the match deadlocked, it had to be decided by penalties with the part-timers holding their nerve to progress to the next round.
United reserve team boss Craig Easton selected a predominantly youthful team along with the more experienced William Edjenguele, Callum Booth and Paul McMullan with the latter named as captain.
Alloa boss Jim Goodwin fielded a strong-looking side with six of the players who drew with United in the league last week, starting at Tannadice.
The Wasps had a succession of early chances including a spectacular overhead kick attempt by striker Greig Spence.
However, it was the home side who took the lead in the 15th minute when a Sam Wardrop cross from the right was knocked down into the path of Smith who drilled the ball past Alloa keeper Neil Parry from eight yards and into the back of the net.
Just after the half-hour mark, Smith embarked on a great run from deep before sending a shot just wide and then shortly after, Parry had to pull off an acrobatic save from a 25-yard McMullan free-kick that looked destined for the top corner.
The home side started the second half well with Matifadza Zata hitting a long-range drive that Parry comfortably saved. The keeper then made two stops in quick succession to keep out a fierce McMullan cross at his near post and then a well-hit Archie Thomas shot.
Billy King made his first appearance of the season from the bench in the 64th minute with Fraser Fyvie also coming on shortly after for the first time since December, last year.
However, despite the reinforcements for United, it was Alloa who equalised in the 78th minute. United defender Luc Bollan sent Dario Zanatta tumbling inside the box with referee Greg Aitken pointing to the spot.
Wasps sub Trouten stepped up and made no mistake with his penalty, firing past home keeper Benjamin Siegrist.
Fyvie had a pop from all of 40 yards with a free-kick at the death but Parry saved to send the game into a penalty shoot-out.
Fyvie, Declan Glass, McMullan and Smith all scored their spot-kicks but Parry saved United’s second, taken by Thomas. That proved the crucial difference with Alloa successfully converting all of their penalties with skipper Andy Graham netting the final one to send his side through to the next round.
