Jo-Wilfried Tsonga pulled out a stunning victory over Roger Federer, and Juan Martin Del Potro followed with a two-set win over Rafael Nadal on Friday to advance to the semifinals of the Rogers Cup in Montreal.
The two stars were ousted after entering the tournament after time off. Nadal was coming back from 10 weeks off to treat tendinitis in both knees, and Federer was out while his wife gave birth to twins.
Down 5-1 in the third set, Tsonga used two service breaks to take the lead and then beat Federer in the tiebreaker for a 7-6 (5), 1-6, 7-6 (3) quarterfinal victory.
After several long exchanges in a first set decided in a tiebreaker, Del Potro broke Nadal's service twice for a 3-0 lead in the second for a 7-6 (5), 6-1 win. Nadal was the defending Rogers Cup champion.
Del Potro advanced to a semifinal meeting with Andy Roddick. Tsonga will face third-seeded Andy Murray.
Dinara Safina repeatedly broke Kim Clijsters' serve during a 6-2, 7-5 victory to reach the semifinals of the Cincinnati Open in Mason, Ohio. Elena Dementieva also advanced with a 6-2, 6-1 win over Caroline Wozniacki.
