Magnificent Latics produced a stunning display of attacking football in a record-breaking 7-0 victory against Oxford United at the Kassam Stadium.
Latics surpassed their previous highest victory 7-1 against Scarborough with some scintillating soccer.
Grigg opened the scoring on 11 minutes and the League leaders never looked back as Nick Powell and Gavin Massey added to their lead before half time.
Grigg added his second early in the second half before completing his well deserved hat-trick on 56 minutes.
Substitute Max Power quickly got in on the act when he added a double in the 62nd and 67th minutes to further compound Oxford’s misery.
Latics further enhanced their position at the top of the table having now accumulated 51 points, scored 49 goals with a positive goal difference of 37.
The possibility of emulating Paul Jewell’s 100 points Division Two winning team now looks within their reach.
Latics retained the same team that had beaten AFC Wimbledon 4-0 last Saturday.
They were on top right from the kick off and they went ahead through the in-form Grigg after just 11 minutes.
Powell set up Jacobs down the left and he pulled the ball back for the Irish striker who finished with some ease into the far corner.
Jacobs was in devastating form and he soon created more chances as Latics surged forward.
They doubled their lead on 18 minutes when Powell rose high in the centre of the box to head home from Lee Evans’ corner.
Soon afterwards Evans hit the bar as Latics were now in total control.
The excellent Massey then added a third goal with a low drive after being played in by Grigg.
3-0 at half time but it could so easily have been six or seven as the visitors had peppered the hosts goal.
Early in the second half Latics had to contend with some initial Oxford pressure but in their first proper attack they made it 4-0. Powell played in Grigg and the striker held off a couple of challenges before firing past Eastwood.
Grigg’s hat-trick came quickly as just two minutes later Massey cut the ball back for the in-the-zone striker to force the ball home despite the attention of two Oxford defenders.
Paul Cook’s men were unstoppable and substitute Power then finished from Massey’s pass.
Latics players and fans were in jubilant mood and Power added his second and Latics’ seventh on 77 minutes as he hit a powerful drive past the dispirited Oxford keeper.
Poor Oxford registered their first shot on target in the 87th minute. Such was Latics’ dominance that they could so easily have achieved double figures. An unforgettable day in the history of Wigan Athletic.
