Zaki's double capped an impressive display from the Egyptian striker
An Amr Zaki brace ensured Wigan picked up their first points of the season as they cruised to victory away at Hull.
The 25-year-old Egyptian stroked home Antonio Valencia's cross for the third and fired in a thunderous drive that cannoned off the bar and over the line.
Wigan went in front as Kevin Kilbane's in-swinging corner was turned into his own net by Sam Ricketts, while Valencia raced clear to double their advantage.
Heskey fired the fourth, before Zaki completed the rout with his second.
The on-loan striker was a constant threat to the Hull defence, who also failed to deal with the impressive Ecuadorian midfielder Valencia.
Steve Bruce had sympathy for Hull
Wigan's poise on the ball was in stark contrast to Hull's direct approach, which is more suited to the football that was on offer when these two teams last met during the 1996-97 season when they were in the fourth tier of English football.
Hull played like they were still scrapping in Football League's basement division as they constantly looked to play the ball long to the isolated Caleb Folan.
Wigan on the other hand were composed and assured and it took them just five minutes to go in front.
Kilbane whipped a corner in low to the near post and in a desperate effort to clear the ball, Ricketts got the slightest of touches to take the ball past Boaz Myhill.
Less than 10 minutes later, things went from bad to worse for the home side as Wigan doubled their advantage.
