FC Tampa Bay transitioned from the temporary USSF Division 2 Professional League to the new North American Soccer League, a second division league, and also changed their home pitch, as they moved across Tampa Bay to Al Lang Stadium in St. Petersburg from George M. Steinbrenner Field in Tampa. Former original Rowdie Ricky Hill was named the club's manager in January 2011.

After winning only 2 of their first 10 matches, the club rebounded to finish 3rd in the league table and qualified for the NASL playoffs. They were upset by eventual league champion NSC Minnesota Stars in the quarterfinals by a score of 1–0. Tampa Bay won their second straight Coastal Cup, by taking three out of four matches against their Florida Derby rivals, Fort Lauderdale. Another highlight was a 1–0 mid-season friendly win over the Bolton Wanderers of the English Premier League at Al Lang Stadium. The Rowdies (along with the rest of the NASL) did not participate in the 2011 Lamar Hunt U.S. Open Cup due to late provisional sanctioning by the USSF.

Note: Game called off in the 67th minute due to inclement weather.
