The APTA granted approval to a new platform tennis ball developed by Marox, Inc. of Carteret, New Jersey. The new ball debuted in the 1994-1995 season.
Under the auspices of the Rules and Equipment Committee, a sample supply of the new ball was tested in February. When all APTA specifications were met, the Board of Directors gave its approval to this new product in March. Random testing of balls taken from production was planned to assure that the specifications approved for the sample would be met.
