Re: Prediction: Del Po wins a major this year
These predictions are dangerous with Del Potro. Looking at his game alone, it's easy to see why someone would predict Slams but there are other factors. Most importantly, will he be fit for all 4 Slams? Last year, he had knee issues in RG and Wimbledon and a bad wrist at the USO that stopped him from playing his best tennis. Managing to be fully fit for all 4 Slams this year would greatly increase his chances, but that's far from a guarantee with Juan.
I think he will continue improving this year and get some big wins, but not sure about a Slam. He will have chances at RG and the USO (maybe even AO with a bit of luck) but it will be quite difficult.
MTF games Grand Slam titles:
Suicide Tennis - Wimbledon 2014
Fill-In-The-Draw - US Open 2014
