Ivan Lendl finished the year ranked ATP world No. 1 for the fourth time in his career. Lendl won ten tournaments during the season, including a major at the Australian Open, and also finished runner-up at another major, the US Open.

Boris Becker was named the ATP Player of the Year. Becker won five tournaments during the season, including two majors at the Wimbledon Championships and the US Open.

The 1989 Nabisco Grand Prix was the only tennis circuit for male players held that year. It incorporated the four Grand Slam tournaments, one World Championship Tennis tournament and the Grand Prix tournaments.^[1]

The table below shows the 1989 Nabisco Grand Prix (to become known in 1990 as the ATP Tour).
