He's actually come on a bit at the end of 2018 and has started this year decently. Anyways I don't think the guy is a world beater yet but he was better than I figured, particularly his movement. Big server and hitter like a typical American but he doesn't move like Isner or the other trees.
I've seen enough of Roger to know when he is having one of "those nights" where his whole game is clicking. Good sign going forward but there is still a lot of work to do. Hopefully he destroys Perseus back to the Homeland. I will root for the Greek hero in a different tournament.
