Berdych was among seven players who entered the Paris Maters with a shot at the three unclaimed invitations to the Tour Finals. His 7-5, 6-4 win over Janko Tipsarevic allowed Berdych, Jo-Wilfried Tsonga and Mardy Fish to qualify for the eight-player Finals, which begins Nov. 20 in London.
Berdych needed five breaks over the two sets to beat Tipsarevic, who took a 4-0 career record against Berdych into Thursday's play.
Tsonga later collected a 6-3, 6-4 win over Andreas Seppi, which would have gained him a Finals spot anyway, but Fish dropped out in the third set with Juan Monaco up 1-6, 7-6 (8-6), 2-1. Fish was treated for a groin injury and it was unclear whether that would affect his availability for London.
Also Thursday, Djokovic, the world No. 1-ranked player, rallied for a 4-6, 6-3, 6-1 win over Viktor Troicki. Troicki forced 14 break-point situations on Djokovic -- and won three of them -- but Djokovic piled up five breaks over the last two sets to advance to Friday's quarterfinals.
Murray, seeded second in Paris, beat Andy Roddick 6-2, 6-2 in 62 minutes in claiming his spot in the quarterfinals. Murray didn't face a break point and won more than half the points when Roddick served.
Also Thursday, Federer, seeded third, beat Richard Gasquet 6-2, 6-4; No. 4-seed Ferrer topped Alexandr Dolgopolov 6-3, 6-2; and John Isner defeated Feliciano Lopez 6-4, 6-2.
