it seems that indoor courts are too fast for american hopes like a young or sweeting every year they had poor results on it but old fishs like a kendrick still doing good
Acually, Don and Ryan generally have pretty good performances this time of season. But it's different this season. Kendrick has always done well in US challengers, and usually Don and Ryan do well in them also. But I think the pressure of making the top 100 has gotten to both in a major way, as both are still very mentally immature.
