Juan Martin del Potro qualified for the semifinals of the ATP World Tour Finals by beating Roger Federer 6-2, 6-7 (5), 6-3 last Thursday.

The win ousted Andy Murray out of the tournament, which means that both Del Potro and Federer both advance to the next round from Group A. The three players were tied after the elimination round, but Murray had the lowest percentage among them.

Last Thursday, Murray defeated Fernando Verdasco 6-4, 6-7 (4), 7-6 (3).
