Filip Pieczonka beat Maxim Mashtakov 6-3, 6-2 in Szczecin, breaking serve four times while losing his own delivery just once. He won 23 return points to Mashtakov's 16 and held all seven of his service games in the match.
Pieczonka broke in the third game of the opening set for 2-1 and again in game five for 4-1, only for Mashtakov to hit back immediately at 4-2; the Pole then sealed the set with a break in game nine. In the second set the decisive move came at 4-2 in game six, and he broke once more to close it out at 6-2.
The return numbers tell the story: Pieczonka took 45% of his first-serve return points against Mashtakov's 26%, and that gap outweighed his own shakier serving, with only 50% of first serves in and four double faults.
