Niemeier won the opening set from defending French Open champion Swiatek and threatened to stage the tournament upset after scoring the first break of the second set with a cross forehand.
Monday marked the first time that Swiatek, the player to beat in women’s tennis this year, lost a set in this tournament.
But the world No. 1 came back from a shaky start to beat Niemeier 2-6 6-4 6-1.
In the fifth game of the second set, Swiatek took four straight points, finishing with an ace, a forehand winner and another ace, before breaking the German in the next game.
“I’m just proud that I didn’t give up hope,” Swiatek said. “I struggled to push it back. I’m pretty happy it worked out. I used my experience to keep my level throughout the game.
“Honestly at first [of the second set]I felt like I was making a few fewer mistakes, but she also started playing less aggressively,” added Swiatek, who broke Niemeier’s serve seven out of 13 times.
“It was easier for me to just play the ball. Yeah, I think I started to be more solid and used the chances I had a bit more.”
With this victory, the Polish champion maintains her streak of not losing against a player outside the top 100 at a Grand Slam event, according to the WTA.
Next, Swiatek will face American Jessica Pegula.
