The purpose of this study is to analyze how man’s match in PSA has been changed since the tin size of the squash court was altered in 2011. It also attempts to attain valuable resources that help to develop training program for squash players as well as instruct players to improve their techniques in accordance to the change of the court. Data was gathered from 16 players who played in the quarter final at J. P. MORGAN tournament champions in 2010 and 2014. The data was calculated based on 14 match videos and the match record cards. Using SPSS/PC Window V20.0, chi-square test(χ2) was evaluated in order to find out the difference among total rate of technique attempts, score factors and score positions. In addition, T-test was conducted to access the difference between match hours and number of rally. The results are following. First, before the change of the tin size, the rate of total technique attempts ranked drive (3349 attempts, 50.0%), drop (1139 attempts, 17.0%), and volley (1086 attempts, 16.2%) in order. On the other hand, after the alteration of the tin size, it was drive (5236 attempts, 60.7%), volley (1197 attempts, 13.9%), and drop (1061 attempts, 12.3%). Second, before the change of tin size, the main score factors were drop (143 attempts, 32.0%), drop failure (79 attempts, 17.7%), drive (78 attempts, 17.4%) and stroke (42 attempts, 9.4%) in order. Whereas, after the alteration, drop (152 attempts, 32.0%), drive (152 attempts, 31.6%), drop failure (75 attempts, 15.6%), stroke (60 attempts, 13.7%) respectively. Third, before the change of tin size, the main score position was center-court (228 attempts, 51.0%), front-court (130attempts, 29.1%), back-court (89 attempts, 19.9%). After the change, it showed the similar pattern, which was center-court (317 attempts, 65.9%), front-court (95attempts, 19.8%), back-court (69 attempts, 14.3%). Fourth, while the match hour was 11 minutes 22 seconds before the change of the tin size, it was 14 minutes 19 seconds. Furthermore, the number of rally was 9.11 times before the change. However, the number of rally increased by 14.5 times after the change.
