Ahead of the 2011 season, the Dynamo declined the option on Onstad's contract and the Canadian keeper decided to retire (he would later come out of retirement briefly). Hall then beat out Tyler Deric for the starting position in preseason. In July of 2011, Hall was named an MLS All-Star. He came on as a substitute in the game, a 4–0 loss to Manchester United. Hall played every minute of the regular season for the Dynamo, anchoring the second lowest scoring defense in the Eastern Conference as well as helping the Dynamo finish second in the Eastern Conference standings. Hall played every minute of the Dynamo's playoff run, keeping 2 clean sheets in 4 appearances as he helped the Dynamo reach MLS Cup 2011, where Houston lost to the Los Angeles Galaxy 1–0.
