A direct result of the merging of the two competitions can still be seen in the qualification rules for the ATP World Tour Finals, which included one notable difference from those of the prior ATP Tour World Championship. The Tour World Championship was meant to include the top eight players on the ATP computer rankings at the end of a season, even though this could mean the exclusion of a Grand Slam champion who had not been able to earn sufficient ranking points in the rest of the year. Present Finals rules ensure the participation of a Grand Slam champion who is unable to earn a top eight ranking at the end of the season and automatic qualification for the top seven players in the computer rankings. The eighth ranked player, however, qualifies only if all Grand Slam singles champions are among the top eight. Any Grand Slam event champion who is not in the top eight but is still in the top twenty is included to the detriment of the eighth ranked player. This situation occurred at the 2004 Tennis Masters Cup, where Andre Agassi, the 8th ranked player in the ATP Champions Race, was excluded from the event in favor of Gastón Gaudio, who had won that year's French Open but was ranked 10th at the end of the year.
