If you mean will he continue to play next year, i say he will for sure. Jiri has a good beginning this year. Why he achieved little in second half year is because the injury starting the US Open. If you mean will he continue to play good tennis, i think it should depend on how much his injury recover, and how he can back to his usual form next year. Jiri is the one who loves his family a lot, which bring him a lot of happiness, so if he retire one day suddenly and decides to enjoy his life with his family, i won't be too surprised. But still, we all hope he can play, and really want to watch him on the court. Jiri, go on your tennis!!
