Clarence Goodson scored an unassisted goal in the 23rd minute as FC Dallas beat Houston 1-0 in the opener of their two-game playoff series Saturday night in Frisco, Texas.

The second game of the aggregate-goal Western Conference semifinal series will be Friday in Houston, where the Dynamo had two wins as part of a 3-0-1 regular-season record against FC Dallas.

Goodson, who was named the team's defender of the year earlier in the day, knocked a shot into the left corner of the net from inside the goalie's box.

The goal was set up by a throw-in from the right side by Adrian Serioux. The pass from 30 yards bounced off Dynamo defender Ryan Cochrane and directly to Goodson.

FC Dallas goalie Dario Sala finished with four saves for his first playoff shutout. The Dynamo finished with a 15-9 advantage in total shots and had nine corner kicks to none for FC Dallas.

RED BULLS 0, REVOLUTION 0: At East Rutherford, N.J., Jon Conway made three saves for New York and Matt Reis stopped five shots for New England, as the two teams played to a scoreless draw in the opener of their two-game goal-aggregate series. The Red Bulls, who last beat the Revolution in September 2005 and are 0-6-3 against them since, had more scoring chances but could not convert them.

WIZARDS 1, CHIVAS USA 0: At Kansas City, Mo., Davy Arnaud scored on a free kick in the 35th minute, giving Kansas City a win over Chivas USA in the opening game of their Western Conference semifinal series. The win gave the Wizards a one-goal advantage when the two-game, aggregate-goal series heads back to the Los Angeles area next Saturday at The Home Depot Center. Both teams had limited scoring opportunities in a game that got physical late in the first half and ended with the two teams combining for 30 fouls. The Wizards broke through when Eddie Johnson was fouled by Paulo Nagamura just to the right of the Chivas goal, about 25 yards out. Arnaud took the free kick and curled a shot around a three-man wall and just inside the right post, past diving goalkeeper Brad Guzan.
