Yeah FajRi,,, able to avenge their defeat to Liu/Ou this time,,, in straight two sets with a nice play of high-speed flat drive, full/half/slice smash, drop shot, placement...
I'd suggest the slice-smash by Fajar Alfian is his signature move,,, because among other pro players that I watch, he's the one using it the most and into full effect: several times got them a point or (more often) de-stabilizing opponent defence, producing short lift to be finished by Rian. That's a nice way of playing!
Based on the SO draw, I think FajRi has the favourite to go all the way to the podium,,, but we'll see.
I notice that They really focus the attack on Ou (as well as in INA Open)...
And about Liu, does he has a back problem? the way he walks doesn't look convincing.
