The Lamar Hunt US Open Cup is, without a doubt, one of the most exciting weeks of the MLS season and this year's third round was no exception.
With all 17 American MLS teams entering the fray against non-MLS sides, some wild matchups were paired together including cross-country travel, amatuer sides taking on MLS and everything else you get with the oldest soccer competition in the country.
While the lower-league heroics of last season that saw eight MLS teams knocked out at the first hurdle weren't quite repeated, there were plenty of giant killings.
