World Tour Finals 2013 - Qualification Scenarios (Group A)

The 2013 ATP World Tour Finals are midway through the Round Robin stages, and if there's one thing that's certain about any big tournament with a round robin format - by the end of day 3, everybody's head hurts from scenarios and calculations. So... let's keep it simple, shall we?

There are two matches left in Group A - Rafael Nadal vs Tomas Berdych and Stanislas Wawrinka vs David Ferrer. Here are the possible scenarios for the group in terms of who wins and in how many sets:

	Nadal in 2	Nadal in 3	Berdych in 3	Berdych in 2
Wawrinka in 2	1.Nadal 2.Wawrinka	1.Nadal 2.Wawrinka	1.Nadal 2.Berdych	1.Berdych 2.Nadal
Wawrinka in 3	1.Nadal 2.Wawrinka	1.Nadal 2.Wawrinka	1.Nadal 2.Berdych	1.Berdych 2.Nadal
Ferrer in 3	1.Nadal 2.Berdych	1.Nadal 2.Berdych	1.Berdych 2.Nadal	1.Berdych 2.Nadal
Ferrer in 2	1.Nadal 2.Berdych	1.Nadal 2.Berdych	1.Berdych 2.Nadal	1.Berdych 2.Nadal

So, to put it simply:

• Nadal already qualified.
• Wawrinka only qualifies if he wins and Berdych loses.
• Berdych qualifies if he wins or if Wawrinka loses.
• To finish first in the group, Berdych must win. If he wins in 3, he needs Ferrer to win as well.
