At her first tournament of the clay season, the Porsche Tennis Grand Prix, top-seeded Radwańska defeated Andrea Petkovic and Karolína Plíšková for the 7th and 6th time respectively. In the semifinal she lost to German qualifier Laura Siegemund who upset Simona Halep and Roberta Vinci on her way to the final. Serena Williams' withdrawal from the Madrid Open elevated Radwańska to top seed of the tournament. She lost to Dominika Cibulkova in the first round. At Roland Garros, 2nd-seeded Radwańska defeated Bojana Jovanovski, Caroline Garcia and Barbora Strýcová before losing to Tsvetana Pironkova. Radwańska's fourth-round match against Pironkova was contested over three days due to harsh rainy conditions. Radwańska led the encounter prior to the resumption of the match in the rain. However while playing in the rain she dropped ten consecutive games, got treatment from a trainer on her hand and subsequently ended up losing the match in three sets. While avoiding major injury during the match, Radwańska needed treatment to her hand the following day.
