As a result of Juan Martin del Potro losing in the semi-finals of the Valencia Open on Saturday, Berdych is guaranteed one of the three remaining spots. The final two positions will be determined at the BNP Paribas Masters Paris, which starts on Monday.
Berdych, who made his debut last year in London, going 1-2 in round robin play, is the first player from the Czech Republic to finish in the Top 10 in back-to-back seasons since Petr Korda in 1991-92.
