what’s abundantly clear is that doyle is completely reworking harrison’s game to avoid the 2h bh altogether by running around it and/or defensively slicing. unfortunately, there’s no way he can he reach the highest echelon of the game with such a glaring weakness. eventually the tour will adapt and expose him. in the meantime, his desire, speed and stamina will keep him competitive.
His two-hander is not bad though. I might even say it is good. It's not as if his forehand is loads better than his backhand. All that being the case, I don't get this tactic, so I hope you're wrong.
BTW, I had no idea Harrison's serve was that big. He was regularly hitting 130. I hope he continues improving. He has got game. He is missing one big weapon though, so he'll have to be awfully well-rounded to be a Grand Slam threat.
