A late strike from Chris O'Grady gave Sheffield Wednesday the bragging rights from their Steel City derby against Sheffield United this afternoon.
United's Lee Williamson went closest to breaking the deadlock in the opening exchanges, but his curling effort struck the crossbar before being cleared to safety.
Wednesday's new signing Michail Antonio had his side's best chance of the half, but he shot over from 18 yards out.
The home side began to dominate after the break, with O'Grady firing just wide of goal from 25 yards out.
The 26-year-old did manage to break the deadlock with his next effort 17 minutes from time when he flicked a headed effort over Steve Simonsen in the away goal.
United pushed players in search of an equaliser during the remaining minutes, but they were unable to find a way past Wednesday goalkeeper Stephen Bywater as Gary Megson's side held out.
