"Obviously, that's a game that worst-case scenario you'd like to walk out of here with a 0-0 tie," RSL's Ned Grabavoy said. "So to drop points at home is disappointing, always."
The Goats had not scored in back-to-back home losses to start the season, but they rode a gritty effort and goalkeeper Dan Kennedy to the victory, surviving a half-dozen strong scoring chances for RSL.
Alvaro Saborio skipped a shot off the top of the crossbar on a half-chip from distance in the 85th minute, for example, and Kennedy made a fantastic diving stop on Fabian Espindola in extra time, to match one earlier in the game.
RSL also had an apparent goal disallowed in the 10th minute, when referee Mark Kadlecik ruled that players broke before his whistle on the free kick that led to the goal.
"We fought," Chivas coach Robin Fraser said. "We battled. … To win in any league, you have to be able to win some games that aren't necessarily pretty. It's about guts and grit, and this was one of those games for us."
Predictably, the Goats came out with a defensive 4-5-1 formation, but they did not totally bunker down until the closing stages.
Still, RSL coach Jason Kreis said he "didn't really think they caused us any problems. … We created a ton of chances. We had the majority of the possession, we were the more attacking-minded team, we were the more dangerous team. On a different night, we win that game by multiple goals."
Alas, on this night, in front of 20,415 fans the fourth-largest crowd in stadium history the game was left to turn on the fluke play in the RSL box.
Rimando had a bead on an incoming cross, but he lost hold of the ball when he collided in midair with Schuler and Townsend. The Chivas forward said he "instinctively kind of swung my foot at it, and it went in."
"Next time around, maybe I punch it," Rimando said, "instead of going up" to catch the ball.
RSL had not lost to the Goats in nearly three years, and never before at Rio Tinto Stadium, which opened at the end of the 2008 season.
"We got a lot of chances to score a goal," RSL's Javier Morales said. "Then, they just have one, and they take it, you know? That's soccer."
