Aljo won the 2nd and lost 1 and 3, the only reason he won the second round was because of his insane pace, an insane pace that had no effect on Yan. Aljo lost round 1 even with a much higher output, he was being outskilled and countered. The third round when Aljo started fading was the beginning of the end for him.
There is an argument for Aljo winning 1 and 2, he was fighting way to actively though, i've never seen someone with such high activity barely win a round, Yan was chilling while Aljo was giving it 110%, it was clear by round 3 Aljo was done and Yan was taking full control.
