3 Things to Know: May 2

On Sunday, No. 1 seed Agnieszka Radwanska and No. 2 seed Angelique Kerber tumbled out in the first round of the Mutua Madrid Open. Radwanska fell to Dominika Cibulkova, 6-4, 6-7 (3), 6-3, while Kerber, who just won a clay-court title in Stuttgart, was ousted by Barbora Strycova, 6-4, 6-2. And the hits just kept on coming for the decimated event when, on the men's side, Roger Federer pulled out with a back injury. (Serena Williams also withdrew last week.)

Timea Bacsinszky won her first clay-court WTA title in Rabat by defeating qualifier Marina Erakovic, 6-2, 6-1. The world No. 15—and last year’s French Open semifinalist—took barely over an hour to seal her fourth career WTA trophy.

This past weekend's ATP tournaments may have lacked for star power, but not for excitement. In the Munich final, Philipp Kohlschreiber won a gritty third-set tiebreaker to beat Dominic Thiem, 7-6 (7), 4-6, 7-6 (4). In Estoril, Nicolas Almagro overcame Pablo Carreno Busta for his 13th career title, winning 6-7 (6), 7-6 (5), 6-3. And in Istanbul, Grigor Dimitrov suffered a third-set meltdown complete with demolished racquets and a game penalty to give Diego Schwartzman his first-ever ATP title, 6-7 (5), 7-6 (4), 6-0.
