(Portland, OR)  --  Portland Timbers head coach Caleb Porter is disappointed last night's game with Sporting Kansas City ended in a 0-0 draw.  Porter says the Timbers failed to take advantage of several breakaways that should have led to scores.  Portland is in the thick of the Western Conference playoff race and has six games remaining on its regular-season schedule, three of them at home.  The Timbers will host the New York Red Bulls this Sunday.
