No. 1 seed Serena Williams squeaked by unranked Heather Watson 6-2. 4-6, 7-5 in the third round of Wimbledon on Friday. Williams survived after falling behind 3-0 in the third and decisive set, rallying to win and set up a battle with her sister Venus in the next round.

An unusually raucous Wimbledown crowd threw their support behind the 23-year-old Watson, who hails from Guernsey, England. But Serena, as she often does, earned the last laugh. In the midst of her furious comeback, Serena won a big point in the 10th game of the third set, then reminded a booing Wimbledon crowd who was in charge with a finger wag punctuated by a “don’t try me.”

Other notable Wimbledon results from the past couple days of action: Rafael Nadal continued his backward slide with a loss to unranked Dustin Brown in four sets Thursday. Roger Federer, Novak Djokovic, Andy Murray and Stan Wawrinka all won their most recent matches. On the women’s side, Sloane Stephens was bounced in three sets Friday, while Venus Williams and Maria Sharapova both won in two.
