However, the one-time Grand Slam champion chose to focus on how she responded after allowing Uchijima a chance to work her way back into the match and said her serves were a key factor in sealing the win.
“I think it was overall a pretty solid match until the end of the second set,” she added. “It’s tough when you haven’t been playing that many matches, you’re not as used to those situations.
“I’m really happy with the way I regrouped and held the serve on that last game because it was really important to win that game.
“I think I was just thinking of my first serve. Because I knew that if I got a good first serve it would help me a lot. I was trying to hit an ace and I did, I hit two. My serves helped me out a lot.”
