CHESTER, Pa. - Graham Zusi had a goal and two assists, leading Sporting Kansas City past the Philadelphia Union 3-1 in the season opener for both clubs Saturday.
Oriol Rosell and Claudio Bieler also scored for Sporting Kansas City (1-0), the defending Eastern Conference champions who trained in Tucson for two weeks last month.
Sporting Kansas City is now 12-4-2 in season-opening games, the best mark in the league.
Zusi's unassisted goal came in the 41st minute and tied it at 1.
Rosell scored in the 66th minute with Zusi receiving the assist from a free kick. SKC put the game away when Bieler scored in the 83rd minute.
Union took a 1-0 lead on a goal by Frenchman Sebastien Le Toux, the club's career leader with 26 goals who was reacquired by Philadelphia in the offseason.
• Whitecaps 1, Toronto FC 0: In Vancouver, Gershon Koffie's goal in the 60th minute lifted the Whitecaps past Toronto FC .
Koffie helped the Whitecaps win their opener for the third year in a row. He scored following some beautiful passing shortly after Vancouver took control of the play.
The Whitecaps won their first-ever MLS game against Toronto in 2011 and beat Montreal in last year's opener en route to becoming the first Canadian team to qualify for the league playoffs.
The loss spoiled the debut of new Toronto coach Ryan Nelsen, a recently retired English Premier League star and New Zealand international, who has undertaken several lineup changes in a bid to improve the team's 10th-place finish in the Eastern Conference last year.
• Dynamo 2, D.C. United 0: In Houston, Ricardo Clark scored and helped create a D.C. United own goal in Houston's win.
In a rematch of the 2012 MLS Eastern Conference championship, the Dynamo took a 1-0 lead on an own goal by United's James Riley in the 80th minute. Off Brad Davis' corner kick, Riley and Clark went up for the ball, with Riley heading it into the net.
Clark extended Houston's lead to 2-0 in the 89th minute, taking a pass from Warren Creavalle outside the right 6-yard box and sending it high inside the far post.
• FC Dallas 1, Colorado 0: In Frisco, Texas, Jackson scored in the 11th minute and FC Dallas held on to beat the Rapids.
