Jo-Wilfried Tsonga has put himself into contention for a spot in the ATP World Tour Finals—and notched a new career milestone to boot.The Frenchman won his fourth title of the year—a personal season-high—with a 6-3, 7-5 victory over Diego Schwartzman of Argentina in the final of the European Open in Antwerp, Belgium. Schwartzman was playing in the final of the tournament for the second year in a row and once again lost to a Frenchman as Richard Gasquet beat him for the title last year.For Tsonga, 2017 has been filled with new achievements, on and off the court. In February, the former world No. 4 captured titles in consecutive weeks for the first time, winning indoors in Rotterdam and Marseilles. Three months later, Tsonga won the first clay-court title of his career in Lyon, France.
