U.S. Men's National Team interim manager Dave Sarachan named his 22-man roster on Sunday for the USMNT's upcoming friendly against Bolivia. Without a World Cup to prepare for, the May 28 match in Chester, Pa. is another opportunity for the U.S. to experiment with younger players and the average age of those on this roster is 22.

“As I’ve talked about throughout this process, the theme is to offer opportunity to this younger generation of talented players that have potential down the road with the program,” Sarachan said in the announcement.

With European seasons coming to an end and MLS still in play, the roster is made up mostly of players plying their trade outside the U.S. Christian Pulisic headlines the group of nine midfielders, which also includes promising youngsters Weston McKennie and .
