Tsonga's record against Top 10 ranked opponents is horrendous this season, its actually the worst of the top 20. Him, Cilic and Dolgopolov all have just 1 win when faced with a player ranked in the top 10 however Tsonga is 1-14 whereas the other 2 are 1-7.
It´s interesting that some players often implodes and others don´t. I remember Hewitt-Roddick 6-3,6-2(Houston 2004 if I remember correctly) when Roddick had 2-1 in second set and suddenly
he lost the match with loosing every single point from there! I couldnt believe what I saw.
