The second period was dominated by Alloa and striker Graeme Brown missed two golden chances to open the scoring. Scott Buist forced a wonder save from Scott Murray before Queen's won it in injury time.
Mark Ferry's 20 yarder was parried back outwards by Jellema and in slid Alan Trouten to knock the ball home from three yards and spark bedlam in the stands.
