Ipswich Town 3 Wolverhampton Wanderers 0
Fortunately for Wolves, League form is no guide to how a team may perform in the Cup.
If it were, Mark McGhee's side might as well save themselves the trouble of making the short journey to Villa Park for their semi-final against Arsenal.
How they managed to avoid becoming the fourth visitors in five to Portman Road to suffer a five-goal mauling, one will never know.
Once Ipswich got up a head of steam in the second half they virtually ran riot and their record of 37 points out of a possible 45 seems guaranteed to earn them a place in the play-offs.
Wolves' own slim promotion hopes took a severe knock as early as the second minute when Ipswich scored in controversial fashion.
Matt Holland's volleyed through ball seemed to be hit more in hope than expectation, but David Johnson's youth probably told in his favour in the race for the ball with Hans Segers.
Dean Richards attempted a goal-line clearance, but not to the satisfaction of Barry Knight, the referee, who had to withstand heated protests from Wolves players.
The goal knocked the stuffing out of Wolves and for the opening quarter of an hour they struggled to cope with an Ipswich side who had scored 20 goals in their previous five games.
Bit by bit, though, Wolves gnawed their way back into the game with the sort of tenacity which has taken them so far in the Cup.
Having had a goal disallowed for pushing, Mixu Paatelainen then found Steve Bull hovering at the far post with a deep cross but the striker headed just over.
In the absence of Steve Sedgley, Wolves' propensity for conceding possession in midfield was certain to rebound on them eventually and sure enough when Richards needlessly gave the ball away after 56 minutes it led indirectly to Ipswich's second goal.
The excellent Bobby Petta accepted the gift and hared off towards goal to earn a corner which he took.
It was only half cleared and Holland, with his back to goal, managed to wrap a foot around it for a well-taken goal. Whereupon Wolves lost their discipline completely.
Osborn was sent off for two fouls in two minutes, both on Petta, and after Mick Stockwell contrived to pass up on a hat-trick in the space of a few minutes Ipswich added a third through James Scowcroft.
