Portsmouth 6-1 Leeds
Portsmouth heaped further pressure on Leeds manager Peter Reid with a thumping win at Fratton Park.
Dejan Stefanovic put Pompey ahead early in the first half only for Leeds to equalise within minutes through Alan Smith.
But Gary O'Neil put Pompey back in front on the stroke of half-time and second-half goals from Hayden Foxe, O'Neil, Patrick Berger and Yakubu Ayegbini completed the rout.
Leeds have now conceded 16 goals in four games and Reid must be wondering how much longer he will be given to turn the club around.
The kick-off was delayed by 10 minutes due to traffic congestion around the game.
Floodlight problems then meant another delay and the game did not start until 1530 GMT.
The hold-up did not seem to bother Portsmouth and they could have been ahead within 20 seconds of the start.
Teddy Sheringham chased Sebastian Schemmel's long ball but he was crowded out as he looked to have earned himself a goalscoring opportunity.
Patrick Berger fired a long range effort just wide and Ayegbini's shot was blocked by Michael Duberry as Pompey threatened.

86 mins: Ayegbini grabs a sixth late on
The home side's dominance paid off after 16 minutes when Stefanovic met Berger's corner to head into the net.
But their lead lasted less than three minutes as the impressive Smith grabbed an equaliser for the visitors.
Seth Johnson's pass put the striker through on goal and he kept his cool to beat Shaka Hislop.
Johnson twice tested Hislop with shots while at the other end O'Neil twice had the chance to put Pompey back in front but wasted both opportunities.
But he had more luck on the stroke of half-time to volley past Paul Robinson from 20 yards with the shot taking a deflection off Dominic Matteo on its way.
Both sides struggled to keep up the hectic pace of the first half in the early stages of the second period.
Leeds had more bookings than goalscoring opportunities after the break with Salomon Olembe, Alan Smith, Seth Johnson and Dominic Matteo all finding their way into the referee's notebook.
Pompey ensured only their second win in nine games when Foxe volleyed home after Sheringham had flicked on a Berger
Berger set up O'Neil for his second goal on his Premiership debut and then Sheringham released Berger who rounded Robinson and slotted home for the fifth.
There was still time for a sixth from Ayegbini as Pompey cruised home and Leeds were left rooted to the foot of the Premiership after their heaviest ever Premiership defeat.
