Austin Berry returns to the starting lineup and Andrew Wenger makes his Union debut this afternoon at a sun-drenched PPL Park. Real Salt Lake is without four of its stalwarts: goalkeeper Nick Rimando, midfielder Luis Gil and forwards Robbie Findley and Joao Plata. But the vistors still have the rest of their spine intact.
Most neutral observers will be watching the battle between Maurice Edu and RSL's Kyle Beckerman, two central midfielders who could be vying for the same place on the United States World Cup team. It's also worth keeping an eye on RSL's Javier Morales, one of Major League Soccer's most savvy playmakers.
