The 2011 season saw Somerset County Cricket Club competing in three domestic competitions; the first division of the County Championship in which despite being within a shout of winning the Championship with two games to go a lack of consistency cost them and they finished 4th, and reached the finals of both one day domestic competitions the Clydesdale Bank 40 and the Friends Life t20. While in international competitions they failed to make it past the group stage in the Caribbean Twenty20 but impressed in the Champions League Twenty20 reaching the semi-finals.
They were captained for the second season by former England international, Marcus Trescothick, who topped the batting table scoring over 2,500 runs saw him named as both Professional Cricketers' Association (PCA) Player of the Year and the PCA's Most Valuable Player of the Year.
