The reviews were rated against subjective evaluation criteria, the scale ranging from poor, moderate, good, excellent and the linguistic variables were converted into numerical values using fuzzy since the expressed opinions may be easy to understand. Findings: Opinions enhance any decision making process, so the influence of opinions from sample data pertaining to performance rating of cricket players are classified as poor, moderate, good and excellent.
