Fresh off MLS Player of the Week honors, Martinez continued his hot streak by opening the scoring in the 13th minute.
The winger did most of the dirty work along the left side to create enough space for his cross.
Martinez made no mistake by one-touching it past Galaxy keeper Jon Kempin.
The Argentine winger then found his fellow countryman alone in front of the net, where Asad tapped it in for the 3-0 lead.
Atlanta United (13-8-7, 46 points) returns to action Sunday, Sept. 24 against Montreal Impact.
