DC question

When was the last time a top 5 player played a dead rubber?

Nadal against Hajek - 2009 final?

^he played against Rochus in the 2011 1st round when he was #1

Federer this year and in 2009 and 2011

^Lol you dont know what a dead rubber is, dou you?
Murray played last year in September against Balazs (Hungarian)
EDIT and this is the correct answer

Thanks a lot, Trollin Stone! :) It's more frequent than I remembered.

Federer against De Bakker today should count, this tie never was alive
