Michael Chang was a dominant Retriever and in his case more a Counterpuncher. Fast around the court and as consistent as a rock, he made on average fewer errors than his rivals with every possible shots: serve, return, forehand, backhand & volley. In total, 51% of his points were won by the errors of his rivals and this result is far above the average of the ATP players.
Retriever / Very high
Michael Chang cannot be qualified of an Offensive player, he was much more the one counterpunching the best in that business. Nonetheless, he also deveoppend an Offensive side and 18% of his total points were won at the net (with or without a volley to play).
Offensive / Medium
During his career, Michael Chang really improved the quality of his serve. Like that he could counterbalance a bit with the best in the business but he was still dominated with the ratio of aces/service winners.
Server / Medium-low
Besides being more solid than his rivals, Michael Chang also got an edge by making on average 30% more points with the backhand than his rivals. Like the Tempo player, he was capable of stepping in and taking the ball on the rise with his backhand. As said previously, his counterpunching skills were also outstanding.
Tempo / High
Michael Chang was much more a Retriever or a Tempo player than a Puncher. His ratio of points won with his forehand was 20% lower than the one of his rivals on average. He still could accelerate slower balls with his topspin forehand but it was not his trademark.
