DIFFERENCES IN SITUATIONAL EFFICIENCY PARAMETERS OF SERVE AND SERVE RETURN BETWEEN MATCH WINNERS AND LOSERS IN 2019 AUSTRALIAN OPEN

The aim of this research was to determine the differences in situational efficiency parameters of serve and serve return between match winners and losers at the 2019 Australian Open. For the purpose of this research, official data was used from all played men’s singles matches in the main part of the 2019 Australian Open draw. Serve and serve return variables were compared from the first three sets in all played matches for each male player who won and lost in the men’s singles category. The examined sample consisted out of statistical data from matches played between 128 tennis players in the main part of the draw. The sample of variables in this research was composed of 11 serve parameters and 11 serve return parameters. All the parameters were derived by using the Infosys system, which was the official system for tracking statistical data at the 2019 Australian Open tournament. Descriptive parameters were calculated for each variable, as follows: arithmetic mean (AM), standard deviation (SD), minimum and maximum values (MIN and MAX). The differences in situational efficiency parameters of serve and serve return between match winners and losers at the 2019 Australian Open were determined by using the independent samples t-est. In this research, the results for serve situational efficiency parameters showed that match winners won statistically significantly more points after the first serve in all sets, as well as that they had more total points won on serve in the first two sets. The results for situational efficiency parameters of serve return showed that match winners statistically significantly differ in several components, among which the total number of return points won after first and second serve and the total number of return points won should be highlighted
