Tottenham cruised to victory in their FA Cup semi-final dress rehearsal with Portsmouth to extend their points advantage in the race for fourth spot.
Peter Crouch nodded Spurs ahead from Gareth Bale's cross and both Bale and Tom Huddlestone then hit the woodwork.
Niko Kranjcar clipped in a second but the hosts barely got out of first gear.
The visitors, who can now be relegated next week if results go against them, went close through Anthony Vanden Borre and Michael Brown but were never in it.
It leaves Portsmouth 14 points adrift of safety with a possible 18 left to play for - and their season really is all about securing that Cup date at Wembley on 11 April.
Spurs, on the other hand, are still fighting for honours on two fronts, though this tie looked less a battle and more a training-ground exercise against a Pompey side lacking in belief and energy.
The Londoners moved five points clear of Manchester City in fifth, though Roberto Mancini's side have a game in hand.
This was a match that always looked a home banker, even if Spurs have been guilty of the occasional lapse at White Hart Lane with defeats to the likes of Wolves and Stoke.
It might have been different for Portsmouth had Anthony Vanden Borre made the most of the first real chance of the game when he found himself clear in the box only for keeper Heurelho Gomes to save his tame effort.
Instead it was something of a procession for Tottenham - even if it took them until the 27th minute to break the deadlock.
Bale, who tormented Pompey throughout, ended one of his many marauding runs from left back with a delightful cross that Crouch nodded in from six yards.
So it was no surprise when Tottenham doubled their lead, debutant Kyle Walker laying it back to Luka Modric, the Croatian's shot blocked, and Kranjcar - like Crouch, a former Portsmouth star himself - impudently flicking in the rebound.
A lapse in concentration at the back then afforded Michael Brown a golden chance to reduce arrears, but the unmarked midfielder scuffed his shot from six yards and the hosts cleared.
It was a rare moment of levity for the travelling fans, though, with their team - undoubtedly missing the ineligible Jamie O'Hara - all too often going through the motions without the necessary application.
The visitors' cause was not helped by what looked like a serious ankle injury to Hermann Hreidarsson, though Tottenham's occasional over-elaborate approach did at least keep the score respectable.
Bentley stung James's palms with a long-range stinger, while Sebastien Bassong should have done better with an unmarked header from a corner that he directed straight at keeper James and Crouch slid a golden chance wide in stoppage time.
Portsmouth, to their credit, created the odd half chance in reply, a Younes Kaboul tackle denying Brown inside the box and Kanu scuffing wide when well placed.
But their day - and arguably season - was summed up by the sight of Danny Webber and David James having to go off injured in the closing minutes, leaving Portsmouth to finish the match with 10 men.
Spurs manager Harry Redknapp's only gripe could be that his side did not go on to win more convincingly.
However, with matches against Ars*nal, Chelsea, Manchester United and Manchester City to come, they have far tougher tasks ahead of them as the season hits the business end.
