Projecting lineups for any U.S. Open Cup game is difficult. Once it gets to this stage, that may be even more true. I'm not sure it's safe to really assume anything.
What we decided to do was go with the group on this one, at least for the Sounders lineup.
The overwhelming picks were Kasey Keller, Steve Zakuani, Nate Jaqua, Tyrone Marshall and Leo Gonzalez. Fredy Montero, Nathan Sturgis and James Riley also received relatively clear decisions. Where it got more contentious was at the second CM position, right wing and the second CB.
Jeff Parke narrowly beat out Taylor Graham; Miguel Montano got the nod over Mike Fucito; and Osvaldo Alonso is inserted via veteran tiebreaker over Mike Seamon.
Chivas USA uses a lot of internationals, so they're lineup is really guesswork since their normal rotation has eight and they can only use five in this match. It looks like they'll barely have enough U.S. players to field an 18-man team, and that will include several very young players with almost no experience.
