Sugita is tiny but he can play clever tennis. His shots are mostly flat and he can move the opponent from side to side when playing well. I didn't see the match but I guess Raonic was a little rusty and Sugita, confident from his win over Devvarman in DC, pushed him hard.
It's been a while, and really tough start to his comeback, but glad to see the win. Milos will be taken down obviously by Rafa, but his goal in this tournament was just to get some match practice which he now has.
