HOUSTON(AP) -- Houston's Pat Onstad made two saves, Columbus'

William Hesmer made one, and the Dynamo and Crew played to a

scoreless tie Saturday at Robertson Stadium.

Columbus (8-2-4, 28 points) extended its unbeaten streak to

three games but saw its winning streak end at two. The Crew

stayed atop the Eastern Conference, keeping their two-point lead

over New York, while Houston (5-7-4, 19 points) extended its

unbeaten streak to three games -- all ties.

Guillermo Barros Schelotto had an opportunity to give Columbus

the lead in the 48th minute, but his header from 10 yards out

went high. Adam Moffat had a breakaway in second-half stoppage

time, but Onstad came off his line and made a sliding kick to

knock the ball out of bounds.

Brian Ching had Houston's best chance to score in the 24th

minute, but after getting a nice cross from the right from Danny

Cruz, Ching missed a wide-open net from inside the 6-yard box

wide left. Cam Weaver nearly gave Houston the lead in the 80th

minute, but his shot from the upper right box missed the far

post by inches and went out.
