On Independence Day, Americans expect to see fireworks. For fans in Columbus and Dallas, they saw just that, as two dynamic duos put on a show on their home fields.

At Toyota Stadium, two South American dynamos gave FC Dallas all that they could ask for in a 3-0 win over the New England Revolution. After a rough stretch, Mauro Díaz and Fabián Castillo are rounding into form once again for Oscar Pareja, as Díaz contributed on all three of Dallas' goals while Castillo scored one of his own.

About 1,000 miles north, another electrifying duo were letting their voices be heard. The Columbus Crew SC's Kei Kamara and Ethan Finlay currently lead the league in goals and assists, respectively, but on Saturday night, they changed roles. Finlay scored both goals in the Crew's win over the Red Bulls, while Kamara turned provider, assisting on both of Finlay's goals.

D: Tyrone Mears (Seattle Sounders) - Scored his first goal in MLS, which just happened to be the winner for the Sounders against D.C. United.

D: Clarence Goodson (San Jose Earthquakes) - In the Quakes' loss in Portland, Goodson was a standout marshalling the San Jose back line.
