Japan's Kei Nishikori overcame Daniil Medvedev in the Brisbane International final on Sunday for his first ATP title in nearly three years and the 12th of his career.
Last year's finalist Nishikori, who prevailed 6-4 3-6 6-2, won 70 percent of points on his first serve and converted five out of 15 break point opportunities to snap a nine-match losing streak in finals.
Tsurenko served for the match at 5-3 in the second set but the tall Czech drew on all her experience to overcome her dogged opponent and regain the title she won at the Queensland Tennis Centre two years ago.
The Ukrainian took an injury timeout after rolling her ankle while being broken in the first game of the third set and was powerless to prevent the world number eight from storming to her 12th career title.
"I think everything was against me today... I felt there is no chance I can win. I felt so far away from playing good tennis tonight," Pliskova, who needed a pep talk from coach Rennae Stubbs to regain composure, said.
"Rennae said 'I am absolutely sure you can win this match,' which gave me some confidence and belief that I can do it.
"I just tried to change the things around a little bit and believed I was going to get a chance... I felt I was getting better with the time."
The victory meant Pliskova joined Victoria Azarenka (2009, 2016) and Serena Williams (2013-14) as the third woman to win the Premier event twice.
