Like AJ said, he graduated and played for USC which is a great tennis program here...and he really did jump into the pro tourneys well. He's a good athlete, good serve (not a ton of power but he can win free points), and that backhand is really good...his favorite shot I would say. Robert serve/volleys sometimes and is pretty good at it, we'll have to see how it does against tougher competition. The backhand, as I said, is great and he likes to jump through it and come into the net off it. He's also a good returner, especially off that BH side.
He does like to play in streaks...he'll be solid and then out of nowhere he'll play 10 points in a row and you wonder who this guy is. He looked pretty comfortable out there during the Bogota challenger, and I believe he's playing a challenger or future this week. Best of luck to him
