It is good enough that he managed to get runner-up when he is not fully fit yet. He was hospitalized for 4 days due to fever and flu right before Thailand Open. Although he has recovered from all those, he is still coughing alot. And that might be one of the reason he is lacking on stamina. For someone who is unfit and has to play for so many days consecutively would be rather draining. Boonsak will come back even strong during WC. He has been performing well since Singapore Open! Boonsak Susu!
