Cambridge United 3-0 Gateshead
Gateshead manager Ian Bogie described the three goal defeat at the Abbey Stadium as his side's worst 90 minutes of the season so far.
The Tynesiders once again conceded the opening goal just before half-time and then suffered a disastrous minute midway through the second half.
The U's doubled their lead and then Stephane Pelonde's first game of the season ended prematurely when the Frenchman was sent off.
The last 25 minutes were a formality as Cambridge strolled to victory and added a third for good measure with a last minute penalty.
"The sending off only papered over the cracks as it was men against boys at times, and we had no goal threat all afternoon," said Bogie.
"There wasn't enough quality on the ball and we gave it away far too cheaply. The second goal took the sting out of the game and it was a very disappointing afternoon.
"Too many players are waiting for things to happen, and a few need to take a close look at themselves as, at the moment, they are not delivering."
Steven Richardson, later to sustain a groin injury, was almost in early on but Danny Potter just managed to gather Wayne Hatswell's headed backpass.
Mackay headed straight at Potter from a Martin Brittain cross while Jim Provett just managed to block a Chris Holroyd header.
Provett then saved from Danny Crow, Andy Parkinson and Holroyd before the deadlock was broken five minutes before the interval.
Anthony Tonkins' pass saw Holroyd cut inside to find the net and Provett then had to save at full stretch from Robbie Wilmot.
Graeme Armstrong replaced the injured Richardson and Phil Turnbull came on for Martin Brittain for the second half.
Armstrong blazed over early on but Gateshead once again lacked a cutting edge and Bogie will attempt to pull a rabbit out of the hat ahead of the imminent closure of the transfer window.
A Wilmot snapshot was parried by Provett but when James Curtis headed a Crow lob off the line Parkinson hammered home the loose ball for the U's second.
Pelonde was then sent off for a foul on Crow that brought a second yellow card, and Gateshead were heading for a fourth defeat from the opening six games.
The ten man Tynesiders held out until the last minute before they leaked a third when Francis handled in the penalty area and Holroyd converted the spot kick.
