The result means Ong Kim Swee’s boys are still winless after two matches in Group A and brought back memories of a humiliating loss to the same opponents in 1991 at Rizal Memorial Stadium.
The Young Azkals, who adopted an attacking approach, were rewarded for their persistence when Haziq bundled in Filipino skipper Stephen Schrock’s corner at his near post in the 72nd minute.
Stunned, Malaysia pushed forward but could not fashion a breakthrough.
The Young Tigers only have one point after opening their campaign with a 1-1 draw against Myanmar on Monday.
With Myanmar beating Timor Leste 3-1 in an earlier match, Malaysia now lie fourth in the group.
Kim Swee, however, remains upbeat about making the semifinals.
“The players must buck up and show character to win the next two matches. Mathematically we still have a chance,” he told Bernama.
Malaysia next play Timor Leste on Monday before wrapping up their group fixtures against Cambodia on Wednesday.
