For many who dream of playing professional tennis without the height to rack up aces like Goran Ivanisevic or the serve-and-volley game to dominate like Pete Sampras did in the '90s, the 175-cm Michael Chang has been a huge inspiration.

That's why the Chinese-American is idolized by fans around the globe. World No. 1 Lleyton Hewitt, at 180 cm, is one of them.

And in the second round of the AIG Japan Open, defending champion Hewitt may have finished Chang's tour of Japan after an effortless 6-2, 6-2 win at the Ariake Colosseum on Wednesday.
