Tatjana Maria comes back to defeat Peyton Stearns in Madrid

Germany's Tatjana Maria rallied from a set down to defeat Peyton Stearns 6-7 (4), 6-2, 7-6 (5) in first-round action Tuesday at the Mutua Madrid Open in Spain.

Stearns fell behind 5-3 in the first set, but used a service break to get back on serve and eventually won a tiebreaker to take the lead in the two-hour, 48-minute match. She couldn't maintain the momentum in the second set, with Maria registering three of her six service breaks.

In the deciding set, Stearns broke Maria's serve in the second game before going up up 3-0, but two games later, Maria broke back without Stearns scoring a point. The two battled to a tiebreaker, with Stearns dropping her serve on match point.

"It was a fight from the first point," Maria told the Tennis Channel. "I started pretty well in the first set. At the end she started to be more aggressive, and she won the first set, but I just kept going.

"I mean, I told myself I feel good on the court. I tried to keep going to be aggressive, to do a little bit more, and, yeah, in the second set, it was like a really tough because I was 3-0 down. I came back to 3-2, 3-all and then the tie-breaker. I was nervous but super close, and I'm happy that I won."
