Which Grand Slam is Tsonga’s best?

Question

The Australian Open wins hands down. In his last three visits to Melbourne Park, Jo-Wilfried Tsonga has been runner-up (2008), a quarterfinalist (2009) and in 2010 has again reached the final four – and will now face Federer in the semis. While Tsonga has reached the fourth round of each of the other three Grand Slams, he is yet to progress any further.
