MLS: Chicago 0, Houston 0 (tie) HOUSTON, July 3 (UPI) -- Chicago's Sean Johnson made a pair of saves and Houston goalkeeper Tally Hall needed to make only one stop in Tuesday's 0-0 draw between the MLS teams. Chicago's Marco Pappa launched a left-footed strike from outside the box that Hall saved in the 12th minute for Houston (6-5-6). Will Bruin missed a chance for the Dynamo just before halftime when his header off a cross from Corey Ashe went over the top of the crossbar. Brazilian playmaker Alex had the best chance for the Fire (8-5-4) in the 80th minute but Houston's Jermaine Taylor blocked his shot from the penalty area.
