TENNIS • Using his hard serve and booming forehand, Juan Martin Del Potro earned the last spot in the semifinals of the ATP on Saturday in London by overcoming the already-qualified Roger Federer 7-6 (3), 4-6, 6-3 in their last round-robin match. Del Potro will face Novak Djokovic in the semifinals Sunday, before Federer takes on Andy Murray.
It was Federer's second straight loss to Del Potro, who also beat him in the final in the Swiss star's hometown tournament in Basel last month. It's the first time a player has beaten Federer in two straight indoor tournaments since Lleyton Hewitt in 2002.
Kilitschko retains three titles
boxing • Wladimir Klitschko retained his WBA, IBF and WBO heavyweight titles, unanimously outpointing Poland's Mariusz Wach in Hamburg, Germany. The 6-foot-71/2 Wach was the tallest opponent Klitschko has faced in his 16-year professional career, but offered little threat against the faster Ukrainian. The judges scored it 120-107, 120-107 and 119-109 for Klitschko. The 36-year-old Klitschko improved to 59-3 (51 KOs), while Wach dropped to 27-1 (15 KOs).
