Wolves remain six points clear at the top of the Coca-Cola Championship after overcoming Blackpool 2-0 at Molineux thanks to a double strike from Chris Iwelumo.
The Scotland striker struck either side of half time to give Mick McCarthy's side their third straight home win and condemn Blackpool to their third successive defeat.
Wolves took the game to the visitors right from the start and their pressure paid off after 30 minutes when Iwelumo rifled home a right-foot drive from just inside the box.
Iwelumo, who played for Scotland in their 1-0 defeat to Argentina in midweek, then tapped in a Michael Kightly cross on 66 minutes to pick up his 13th of the season and put more light between his side and Birmingham at the top of the table.
Reading's unbeaten home run was ended by Southampton who ran out 2-1 winners at the Madejski Stadium thanks to a Bradley Wright-Phillips double.
Wright-Phillips met a brilliant Lloyd James cross at the back post to give the Saints a surprise lead before he doubled their advantage with a 20-yard bullet on 49 minutes.
Jimmy Kebe pulled one back for Reading eight minutes later after Kelvin Davis spilled a Kevin Doyle shot but the Saints held on to pick up their first win in three.
