Orlando City captain Kaka scored in his long-awaited return, while reigning MLS champion Seattle Sounders rallied from three goals down to earn a draw against New England Revolution.

Back on the pitch after a hamstring injury suffered on the opening weekend of the season, Kaka made an immediate impact as high-flying Orlando accounted for Colorado Rapids 2-0 on Sunday (AEST).

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.

Seattle completed a stunning second-half comeback to earn a 3-3 draw with New England.

Trailing 3-0 in the 75th minute, the Sounders rallied through Nicolas Lodeiro before Will Bruin equalised five minutes from time.

Osvaldo Alonso scored the winner with two minutes remaining at home to Revolution, which played out its third consecutive draw.

It was a five-goal thriller in Columbus as Jack Harrison's brace lifted New York City past Crew 3-2.

Yangel Herrera – on loan from parent club Manchester City – also scored for New York, who trailed 2-1 early in the second half.

Sporting Kansas City eased past Real Salt Lake 3-0, Montreal Impact lost 2-1 at home to Vancouver Whitecaps, FC Dallas and Portland Timbers drew 2-2, San Jose Earthquakes edged Minnesota United 1-0, while LA Galaxy played out a goalless draw against Philadelphia Union.
