Tsonga’s form over the last 12 months
In 2011 six players made it to a slam semi-final: the big 4, plus Tsonga and Ferrer.
Tsonga beat Federer in the Wimbledon quarter-final, and then lost to Djokovic in four sets in the semifinals.
At the Canada Masters later that summer he beat Federer again, and reached the semifinals, where he retired against Djokovic when 6-4 3-0 down. At the US Open he faced Federer for a third time in quarterfinals. Federer took revenge in straight sets.
Tsonga then had a good autumn indoors, winning the Metz and Vienna tournaments and reaching the finals of the Paris Masters and the YEC in London. He lost both finals to Federer. Between Wimbledon and the end of the year his ranking rose from 19 to 6.
At the start of 2012 he won the Doha ATP250, beating Monfils in the final, but then lost to Nishikori in a five-set match in the fourth round of the Australian Open. At both Dubai and Marseille he lost to Del Potro. Over the spring he reached the quarterfinals of the Miami, Monte Carlo and Rome Masters, and the French Open.
At Wimbledon he was drawn in Nadal’s quarter, and in the quarterfinals beat Kohlschreiber. He lost his semifinal against Murray in four sets.
Given his comfort playing on grass, and the best-of-three format, his winning a medal at the Olympics next month would not come as a surprise.
