A couple of games into the match against Greek world No. 487 Michail Pervolarakis at the ATP Cup, 35th-ranked Jan-Lennard Struff realized that he had to change some things. Pervolarakis, who entered the match as the big underdog, wasn't backing down to the German early on as he claimed the first break of the match in the fifth game.
After dropping his serve, Struff immediately raised his level of play as he broke the Greek four times and lost no service games in the remainder of the match to earn a straight-set win. "He was playing very aggressive and I didn't find him keen in the first game and I told myself that 3-2 down...
I said to myself, 'I need to find a way for to go out there and to battle back now.' And I did find a way and it was very important for me to get myself up again," Struff said, per the ATP Cup. Pervolarakis, a former world No.
433, doesn't have much experience on the biggest stage as he has spent the majority of his career on the Futures and Challenger Tour.
