I know that sometimes people worry that players may have less incentive in later round robin matches when they’ve already clinched a spot in the “next round.”  However,  overall I think that round robins are a win-win strategy for fans and players in the year-end championships.  Players who are coming off a long season and possibly even a late season layoff for injuries, e.g. Henin-Hardenne, Mauresmo and Clijsters, have a chance to play themselves into form and even make the next round despite a loss.  For the tournament director, there is a set schedule of matches for the first few days which enables them to promote both the event and the players more effectively.  Fans win as well because they have multiple opportunities to see the top players compete against each other.  Round robins are great for tennis, but let’s continue to save them for the year-end championships when the elite 8 compete against each other.
