*MLS clubs now know their first opponents in the U.S. Open Cup following 16 second-round matches Tuesday. D.C. United will visit the third-division Richmond Kickers, who defeated the amateur Aegean Hawks, 4-0, at Maryland SoccerPlex. United, which has two victories and a defeat to the Kickers in the Open Cup since 2004, will play at 7 p.m. next Tuesday at Richmond City Stadium.

The biggest surprise of the tournament (and another reason this event is cool): Cal FC, an amateur team coached by former U.S. national team star Eric Wynalda. After defeating a fourth-division side in the first round, Cal went on the road to crush the third-tier Wilmington Hammerheads, 4-0, and earn a trip to Portland to face MLS’s Timbers.
