The history of the modern tennis racket can be
traced back to 1975 and the release of a Weed USA
model designed with a light, over-sized frame and an
enlarged sweet spot that made both control and
power easier. The Weed line of rackets did not
perform well commercially.

3.  In 1976, however, the Prince Classic did. Designed by
Howard Head of the Head and Prince tennis racket
companies, the Prince Classic, along with the
upgraded Prince Pro, featured a sleek aluminum
design and a sweet spot more than 50 percent larger
than those offered by comparable wooden rackets.
Over the course of the next decade, carbon-
composite rackets began to take over tennis at both
the professional and recreational levels. In the 1986
US Open men’s final, a decade after the release of
the Prince Pro, Miloslav Mecir of Slovakia became the
last player to use a wooden racket at the Grand
Slam level in his loss to Ivan Lendl.
