Southampton 3-2 Leeds
Southampton made a mockery of fears they would suffer a post-FA Cup hangover by beating a ramshackle Leeds at St Mary's.
Brett Ormerod's second goal in a week gave Saints a lead they never looked like relinquishing.
Further strikes from James Beattie - his 22nd Premiership goal of the season - and Anders Svensson made victory certain while Leeds' misery was compounded by the third sending-off this season for Alan Smith.
Harry Kewell's controversial late strike - which Southampton manager Gordon Strachan felt was offside - and Nick Barmby's injury-time goal gave the scoreline a flattering sheen.
But Leeds never really looked likely of claiming a point from a game where they were always second best.
Saints received a rapturous welcome as they returned home a week after clinching their first FA Cup Final place since 1976.
31 mins: Ormerod gives Saints the lead
45 mins: Beattie doubles the home side's lead
53 mins: Anders Svensson adds to Leeds' misery
61 mins: Alan Smith sent off for Leeds
80 mins: Harry Kewell pulls one back for Leeds
90 mins: Nick Barmby's injury-time goal makes the scoreline respectable
A rather flat start did little to diminish the home fans' enthusiasm, although they were thankful to see Mark Viduka flagged offside after six minutes.
Beattie headed just wide from Wayne Bridge's cross and Ormerod blasted over as Saints responded.
And Saints' fans were holding their heads in frustration on 15 minutes as Matt Oakley hammered in a shot which Paul Robinson punched away.
At the other end, some typically fluid Kewell trickery helped him set up Smith, who shot wide of Paul Jones' goal.
Robinson was again in action on 27 minutes, saving well from a deflected free-kick from the ever-lively Beattie.
But the Leeds keeper could do nothing on 31 minutes as the home side took the lead.
It was a fiery encounter at St Mary's
Anders Svensson's shot was parried by Robinson but Ormerod was on hand to convert the rebound.
Southampton were looking increasingly confident, and after several more half-chances, netted a deserved second on the stroke of half-time.
Inevitably it was Beattie who got it, scoring for the sixth successive Premiership game with a mis-hit left-foot finish after Ormerod flicked on Fabrice Fernandes' cross.
Saints maintained their momentum after the break with Beattie continuing to trouble the Leeds defence.
He duly created Saints' third with a surging run and cross which was converted with aplomb by Anders Svensson.
Leeds' struggled to keep their discipline and Smith was booked for a challenge on Ormerod on 58 minutes.
And their miserable afternoon went from bad to worse when Smith was sent off four minutes later for a second yellow, this time for a challenge on Michael Svensson.
Saints almost made it four, but Beattie missed with a close-range header, while Ian Harte had to head off his own line during another Southampton attack.
Harry Kewell did pull back a controversial goal for Leeds on the 80th minute, much to the fury of Strachan.
And though Barmby grabbed another in injury-time, there was no doubt the better team had won the day.
