HOUSTON (AP) _ Sporting Kansas City's Jimmy Nielsen made three saves, and Houston's Tally Hall had two stops as Kansas City and the Dynamo played to a 0-0 tie in the first leg of the Eastern Conference finals Saturday.
The second leg will be Nov. 23 in Kansas City after a two-week break for FIFA international games.
Houston appeared to take a 1-0 lead in the 17th minute as Kofi Sarkodie got a pass in the right box and sent one across into the net, but Sarkodie was called offside.
Nielsen kept the game scoreless in the 29th minute, making a diving save to his right on Boniek Garcia's free kick from 30 yards out.
Teal Bunbury had a shot from 10 yards out stopped in the 39th minute. On the counterattack, Will Bruin had a shot from 35 yards out in the middle sail just above the crossbar.
Nielsen stopped another Houston opportunity in the 57th minute, saving Cam Weaver's header from 8 yards out.
