Czech qualifier Nikola Bartunkova knocked off No. 9 seed Diana Shnaider of Russia 6-2, 6-7 (2), 6-3 in a back-and-forth first-round match at the Berlin Tennis Open on Monday.
Bartunkova fell behind 3-0 in the second set, rallied for a 5-4 lead and served for the match before Shnaider saved double match point, then prevailed in the tiebreaker. Shnaider went up 3-0 again in the third set but Bartunkova ripped off six straight games to turn the tables.
Only two other main-draw matches were played on Monday.
Belgium's Elise Mertens charged back for a 1-6, 6-3, 6-0 victory over Russia's Liudmila Samsonova, and Russian Ekaterina Alexandrova won her first set 6-1 before Austrian opponent Anastasia Potapova retired.
