That's no beginner. He's got a solid forehand and a good serve motion. I only saw one backhand (ran all the way into the doubles ally once to hit a forehand). He's been playing for awhile.
Sorin playing tennis since March,2005 and his coach is me.He ran to hit inside-out because his one handed backand it is in construction.He had two handed backand until March,this year..Actually,Sorin is nr.6 in National Ranking,8-10 years category..
