Re: What are your expectations of Jo Wilfried Tsonga for the grass season?
Very well could be the queens favorite odds wise, so I wouldn't be stunned if he took that.
Wimbledon QF/SF. Don't see him winning Wimbledon personally. To win wimby outside the big4 you essentially have beat to 3 of them, and you can only hope one of them is Murray. Can Tsonga beat any one individually? Of course.
However, he will still be relatively big underdogs on grass vs the big3 so to beat 2-3 of them is very tall task that is extremely unlikely.
Olympics - bronze/silver at best. See above.
