FRISCO -- After 19 years of disappointment, near misses and heartbreak, FC Dallas snapped its trophy drought, beating the New England Revolution 4-2 to win the Lamar Hunt U.S. Open Cup on Tuesday night at Toyota Stadium.

"The boys proved that we can do it after that many years with that many people involved with the club waiting for a trophy, we made it real," coach Oscar Pareja said after the match. Congratulations to this group of players and coaches that has helped us this much, to get to this point."

For 10 minutes, there was fear that the wait might continue. That fear dissipated quickly. While the Revolution went ahead in the first half, the early goal seemed to snap FCD to life. The team dominated the rest of the first half, taking a 3-1 lead into the break and ending the opening portion with 12 shots to the Revolution's one. FCD continued to control the match in the second half.

The control came thanks to Mauro Diaz, who had a hand in all four FC Dallas goals. Diaz had three assists and set up the play that led to FCD being awarded a penalty kick, which he converted.

"It's a collection of what he has done here this year," Pareja said. "Mauro showed the heart of this club and he showed the heart (his teammates have) tonight. These boys wanted to win, and Mauro led them. I'm very happy with him, very happy for him because that's the standard he can leave here at this club as a legacy."

Just five minutes had passed when Revolution forward Juan Agudelo, his back to goal, took a pass near the top of the box, turned past center back Matt Hedges and sent a smooth shot past goalkeeper Chris Seitz and into the back of the net. As Agudelo celebrated with Revolution fans, FCD faced its fourth deficit in this year's tournament.

From there, it was all FCD.

In the 15th minute, the team battled back. Diaz whipped a ball in toward Maxi Urruti. The Argentine used his left foot to pop the ball in the air, then smashed a shot home with his right to tie the score 1-1.

FCD was hoping for a chance to go ahead in the 20th minute. Diaz shifted past one defender, then another and played a ball toward Mauro Rosales. As Rosales rose to head the ball, Je-Vaughn Watson sent Rosales into the ground for what the sellout crowd of 16,612 was certain was a penalty. But referee Baldomero Toledo declined to blow his whistle.

In the 40th minute, Diaz teed up Hedges for a leaping header past New England goalkeeper Brad Knighton.

Hedges was involved again a few minutes later, making a back-post run on a free kick and getting dragged down, with the assistant referee signaling to Toledo to point to the spot. This time Diaz stepped up to score the goal himself, going to the goalkeeper's right and extending the lead to 3-1 ahead of the break.

The speed of play slowed in the second half, but FCD kept up its intensity.

The lead was extended shortly after the hour mark when Diaz once again linked up with Urruti.

And if the champagne wasn't already on ice, the victory seemed to be with Diaz hitting a free kick to Urruti's head and into the back of the net. But the play came back with the forward called for offside.

Agudelo tried to make things more interesting, finishing in a seeing-eye cross from Teal Bunbury to make it 4-2. But FCD slowed the pace and claimed the victory.

FCD has three days to enjoy its triumph before returning to league play Saturday. The team, leading the Supporters' Shield standings, hopes Tuesday's trophy win will be the first of many.

"It's unreal. The feeling is so amazing," FC Dallas president Dan Hunt said. "I'm so proud of the guys. The performance tonight was as top-class a performance as I think you'll ever see. There's a huge weight off our shoulders. My biggest fear was we weren't going to get the first one.

"We kept ourselves in a spot to try to get the treble. No matter what happens from this moment on, these guys will always be champions, and I'm so proud of them."
