VANCOUVER, British Columbia — Kenny Cooper scored in the 25th minute and the Portland Timbers beat the Vancouver Whitecaps 1-0 in the first MLS game played at the newly refurbished BC Place Stadium.The Timbers (11-13-7) took advantage of a Whitecaps mistake to score the only goal they would need as defender Alain Rochat turned the ball over at midfield. Midfielder Diego Chara fed Cooper a perfect ball and the big forward hammered a shot from the top of the box over the outstretched fingers of Vancouver goalkeeper Joe Cannon.The Whitecaps (4-16-10) pressed for the tying goal in second half but the Portland defense was equal to the challenge.Vancouver striker Eric Hassli missed a scoring chance on a header in the final moments, and then pounded the turf with his fist.Among the sold-out crowd of 21,000 celebrating the return to BC Place was a large contingent of Timbers fans. Dressed in green, they sang and waved flags throughout the match.The Whitecaps supporters did their best to drown out the visitors by pounding drums and chanting constantly.Included in the renovations is a retractable roof that opened moments before kickoff. A huge video board hanging in the center showed the action in HD so sharp it looked like you were watching at home on your own TV.The game was played on a modern Polytan synthetic surface, considered one of the best for soccer. Throughout the building there are 800 Wi-Fi points and 1,150 digital screens, wider seats, improved acoustics and enhanced concession and bathroom facilities.
