English star David Beckham started his first game for the Galaxy and scored his first goal on a free-kick in the 27th minute as Los Angeles beat DC United 2-0 in the SuperLiga semifinals.
Beckham also set up the Galaxy's second goal. He sent a long pass to a streaking Landon Donovan, who scored on a breakaway in the 47th minute for a 2-0 lead.
The Galaxy advanced to the August 29 tournament final in Carson against Mexican club team Pachuca, which tied Houston 2-2, but won 4-3 on penalty kicks on Tuesday.
The winning team earns USD 1 million, which the Galaxy could put toward paying Beckham's USD 6.5 million yearly salary.
Beckham also earned his first yellow card after fouling United's Jaime Moreno in the 18th minute. Beckham got fouled once in the first half, when he also took two corner kicks.
Fans cheered and women screamed as Beckham prepared to take a 26-yard free kick. After he connected inside the left post, he was mobbed by teammates. Goalkeeper Joe Cannon even scampered across more than half the field to join the celebration.
Beckham waved to the crowd a couple times while blue, gold and white confetti fluttered through the air, reminiscent of the scene when he was introduced amid much fanfare July 13.
He was stopped on a 26 metre free-kick in the 58th minute, when United goalkeeper Troy Perkins leaped to the left and caught the ball.
In all, Beckham played 63 minutes. He clapped his hands above his head while turning in a circle to acknowledge the cheers before putting the captain's armband on Donovan and heading to the bench.
Beckham had played just 37 minutes in two previous games because of a nagging left ankle injury that didn't allow him to practice with the Galaxy for the first time until Tuesday.
The victory avenged the Galaxy's 1-0 loss to United last week in Major League Soccer action, when Beckham made his league debut on the road.
He was named captain for Wednesday's match, a title previously held by Donovan. Beckham actively urged on his teammates, talking to them and waving his arms during play.
As the half-time whistle blew, Beckham bent over and adjusted his socks, then stood up, a broad smile on his face as he waved and walked off the field.
The game, which wasn't part of the Galaxy season ticket package, attracted an announced crowd of 17,223 in the 27,000-capacity stadium.
