LONDON — Top-ranked Serena Williams hasn't won a Grand Slam since Wimbledon a year ago, but the 21-time major champion appeared confident about her chances of retaining the title on the eve of the tournament.
"Honestly, I don't feel any pressure," Williams said at a news conference Sunday. "I feel good and confident."
Williams surprised many by failing to win any of the past three Grand Slams.
She fell to Roberta Vinci of Italy in the 2015 US Open semifinal, Angelique Kerber of Germany in the 2016 Australian Open final and Garbine Muguruza of Spain in the French Open final this month.
Instead of bemoaning those losses, she prefers to focus on coming back stronger.
"I think it's important to learn from every loss that you have," she said. "I think, in particular, throughout my whole career (I) have been able to learn a lot to come back a much better player."
Williams enters Wimbledon maintaining her No. 1 ranking for what will be an impressive 300th week at the top.
Nevertheless, Muguruza, Kerber, Agnieszka Radwanska and Simona Halep are all positioned to oust Williams from the top spot by the end of Wimbledon.
Williams will play 148th-ranked qualifier Amra Sadikovic, a player she admits knowing nothing about, in the first round Tuesday.
"It doesn't matter who I play," she said. "It doesn't matter to me."
