The Union was without midfielder Roger Torres (knee surgery) and forward Danny Mwanga (rib contusion). Captain Danny Califf, the team's central defender, was scratched just before kickoff with a hamstring strain and replaced by rookie Raymon Gaddis.
"It feels great knowing that we got the three points in my debut," said Gaddis, who played the full match. "Hopefully the momentum will carry on to next week."
Now, the Union has a trio of testy matches against Western Conference opponents. First up is a road trip to play Chivas USA on Saturday (10:30 p.m., TCN) followed by San Jose at home on Saturday, April 28 (7 p.m., CSN). Seattle opens the Union's slate of matches next month on Saturday, May 5 (4 p.m., NBC Sports Network) at Century Link Field.
All this before a nationally televised showdown with Eastern rival New York at PPL Park on Sunday, May 13 (1:30 p.m., ESPN2).
"It was extremely important for these [guys] in the locker room to have this feeling and get three points," said Union boss Peter Nowak. "We deserved it a long time ago . . . A win is a win, it was like a 65-minute feeling that it had to hold up. They're starting to see that the work pays off. Now, we have to keep going."
