Lee Bullen was left to rue missed opportunities after his Owls Under-21 side drew 2-2 with Leeds United in their final home match of the campaign.
Watched by Sheffield Wednesday head coach Stuart Gray, the hosts surged into a two-goal lead after 28 minutes at Hillsborough following a penalty by Emmanuel Dieseruvwe and a strike by highly-regarded winger Jack Stobbs.
Lewis Walters reduced Leeds’ deficit just before the half-hour mark and substitute Frank Mulhern levelled things up in stoppage time from close range.
Bullen said: “I thought we deserved to win. We scored a couple of great goals but we missed some good chances.
“If you don’t take your opportunities, you are going to get caught by a sucker-punch and unfortunately we did late on so we are disappointed.”
Wednesday broke the deadlock from the penalty spot in the fifth minute after Afolabi Coker was penalised for bringing down trialist Robbie Cotton. Dieseruvwe, who has enjoyed loan spells at Hyde and Fleetwood Town this season, stepped up and coolly stroked home from 12 yards.
Stobbs doubled the hosts advantage, rifling in a low right-foot shot after a great counter-attack involving Paul Corry and Dieseruvwe.
But Wednesday’s joy was short-lived as Walters pounced following good play by Richard Bryan.
Adam Davies, out of contract in the summer, kept out efforts by Chris Dawson and Kalvin Phillips as Leeds finished the half on top.
Dieseruvwe should have added a third but he some how steered Stobbs’ fine cross wide before Franck Betra’s header was superbly tipped on to the crossbar by Eric Grimes.
Those misses proved costly in the dying embers of the derby.
Davies could only parry Luke Booker’s drive straight into the path of Mulhern, who slammed in the equaliser.
Owls: Davies; Nortey, Beatson, Obileye, Floro (McKenzie 73); Stobbs, Mugabo (Lambin 83), Cotton (Hanna H-T ), Corry; Betra, Dieseruvwe. Substitutes: Hinchliffe, Savic.
