Back on the pitch following a hamstring injury suffered on the opening weekend of the season, Kaka made an immediate impact as high-flying Orlando accounted for the Colorado Rapids 2-0 on Saturday.
After Carlos Rivas broke the deadlock in the 70th minute, former AC Milan and Real Madrid star Kaka came off the bench to seal Orlando's fifth successive home victory in the first minute of stoppage time.
Kaka was on hand to tuck away the rebound from inside the six-yard box after Cyle Larin's strike hit the post.
