Chung broke in the opening game of the second set with a delightful backhand across the net taking the line. But Sandgren began to get more into the contest and broke back in the fourth when Chung's forehand was wide. Sandgren broke again in the eighth and was serving for the second set before he was broken with a netted forehand. Chung maintained his level in the tiebreaker, getting to set point before he forced a Sandgren forehand long. Chung broke in the fourth game of the final set and but temporarily his victory charge was stalled before he got home on his sixth match point.
