Madison Brengle (born April 3, 1990) is an American professional tennis player. Her biggest success she had in early 2015, reaching her first WTA Tour final in January, followed by a fourth round major event appearance at the Australian Open. In May, she reached her career-high singles ranking of No. 35. Her greatest victory came in 2017 over world No. 2, Serena Williams. She has won two singles titles and one doubles title on the WTA Challenger Tour, 19 singles and seven doubles titles on the ITF Circuit. In August 2007, she was ranked fourth in the world in juniors. Brengle then toiled for years in the ITF Circuit. Over the course of 24 consecutive majors between 2008 and 2014, she failed to make it out of the pre-tournament qualifier. The streak ended when she earned a wildcard for the 2014 US Open main draw, which she capitalized on for her first major match-win. Her ranking soon rose into the top 100 for the first time in September 2014. Early life Brengle was born and raised in Dover, Delaware, and is Jewish. Her mother (Gaby née Gamberg) coaches her, her father is Dan Brengle, and she has a brother named David. Playing style Brengle is what some coaches call a scrappy player, and her game is built around counter-punching and outlasting her opponents in long rallies while waiting for her opponent's error. When serving she uses an abbreviated service motion. Her forehand has a low follow-through. Sometimes on her backhand she will drive the ball flat, using a half-swing. Brengle moves quickly around the court, and is willing to battle to win her matches. Junior career As a teenager, Brengle participated in an experimental USTA training regimen. In 2006, she won the Easter Bowl doubles championships with Kristy Frilling, defeating Sanaz Marand and Ashley Weinhold in the final. In 2007, Brengle reached the Australian Open girls' singles final, before going down to Anastasia Pavlyuchenkova. Brengle and Julia Cohen were the top seeds at the 2007 French Open girls' doubles competition, but the team lost in the first round. Seeded seventh, Brengle lost in the final of the Wimbledon girls' singles competition to Urszula Radwańska, in three sets. Brengle and Chelsey Gullickson reached the girls' doubles semifinals there before losing to top seeds and eventual champions, Pavlyuchenkova and Radwańska. In August 2007, she was ranked fourth in the world in juniors.
