No. 36-ranked Pliskova squandered a 5-1 lead in the match after she twice broke the top-seeded German in the first set before losing the next six games.
Lisicki fired five aces in the second set and twice broke her Czech opponent's serve, in the fourth and eight games, to clinch the final in just under 90 minutes.
Lisicki won her last WTA title in Dallas in 2011. It was also her third victory against Pliskova this year after victories at Wimbledon and at the Madrid Open.
