On December 14, 2010, Ashe signed a new contract with the Dynamo. After starting the first 2 games of the season at right midfielder, head coach Dominic Kinnear decided to start Ashe at left back for the third game to better handle New York Red Bulls winger Dane Richards's pace. Despite Richards scoring in the game, 1–1 draw, Ashe did good enough for Kinnear to move him to starting left back full-time. During the first 4 seasons of his career, Ashe had struggled to find a consistent spot in the starting lineup, with All-Star Brad Davis getting the majority of starts at Ashe's preferred position of left midfielder. He took advantage of the opportunity and made the left back spot his own, starting 28 games at left back during the regular season. Ashe's strong performances earned him a spot in the 2011 MLS All-Star game, where the MLS All-Stars took on Manchester United. During the regular season he made a career high 32 regular season appearances, with 30 of them being starts. The majority of both were at left back. Ashe helped Houston return to the playoffs in 2011, finishing 2nd in the Eastern Conference. Houston faced off with the Philadelphia Union in the conference semifinals, with Ashe playing every minute as Houston won 3–1 on aggregate. In the conference final, Ashe once again started at left back as Houston faced off with Sporting Kansas City. However, left midfielder Brad Davis went down with an early injury, forcing Ashe to move up as Jermaine Taylor came in to play left back. Houston defeated Kansas City to advance to MLS Cup 2011. With Davis unavailable, Ashe got the start in midfield. In a close game, the Dynamo ultimately fell short, losing 1–0 to the LA Galaxy.
