In the second set, Thiem started to slowly find his rhythm again. World no. 3 had 2 breakpoints in the 4th game but he failed to convert them. Then again, he needed to keep the composure on his service game. And Thiem succeeded in doing so. He lost only 2 more points on his service till the end of the set. He also converted 2 out of the 3 following breakpoints he had to win the set 6-2 and force the third decisive set.

Unlike the first set, this time he didn't lose the lead. 'Domi' made no more mistakes on his service game. He was almost flawless on his service now and won the set 6-2 to become the first finalist at Thiem's 7.
