agreed. he will get better.
he has been putting in the hard yards.
His serve remains a huge problem. Very low % and weak as shit. Henin hit several return winners off his serve in mixed doubles match, ffs. Trust me, he won't be getting close to top 20 with that serve and declining movement, not to mention no true weapon. He is a hard worker who deserves respect, but at his age, when he comes up against a top 10 player, his limitations will soon become apparent.
