The decision to go with a heavy MLS-based roster was by design for U.S. coach Bruce Arena. The notable newcomers are joined by a handful of national team veterans, including Graham Zusi, Brad Guzan, Matt Besler and Alejandro Bedoya.
It's also a chance for those whose opportunities with the U.S. in the past year have been limited — Gyasi Zardes, Dax McCarty, Jordan Morris, to name a few — to flash in a more prominent role.

THE OTHER CUP: The quarterfinals for the U.S. Open Cup will include one of the best stories in American soccer.
USL club FC Cincinnati continued its impressive run in the tournament by knocking off Chicago on penalty kicks in the round of 16 before a crowd of more than 32,000. Goalkeeper Mitch Hildebrandt made three saves in the penalty shootout to send Cincinnati to the final eight against fellow USL side Miami FC.

In another non-MLS competition, Toronto beat Montreal 3-2 on aggregate in the Canadian Championship thanks to Sebastian Giovinco's goal in the closing seconds of the match.
ROAD RIVALS: Last week's handful of rivalry showdowns went in the favor of the road teams.
The one victory by a road team went to New York City FC and its impressive 2-0 victory over the New York Red Bulls. NYCFC got goals from Jack Harrison and Ben Sweat to earn the club's first points ever against their Hudson River rivals at Red Bull Arena.
The two draws for road teams came in decidedly different ways. FC Dallas got a goal early in the second half from Maxi Urruti for a 1-1 draw in the Texas Derby with Houston. Seattle's 2-2 draw at Portland in a Cascadia showdown was even more dramatic thanks to Clint Dempsey's header in second-half stoppage time to pull the 10-man Sounders even. The draw dropped Portland to 2-3-5 in its past 10 MLS matches after starting the season with five wins out of the first eight.
There is one more rivalry showdown this week: the California Classico where more than 50,000 are expected for San Jose's match against Los Angeles at Stanford Stadium.
