Citi Open at Rock Creek Park Tennis Center: A deep field of pros will head to Rock Creek Park Tennis Center to sweat it out for the Citi Open championship, a Washington tradition that’s celebrating its 50th anniversary. Sloane Stephens, Caroline Wozniacki, Ekaterina Makarova, Andy Murray, Francis Tiafoe, Alexander Zverev and Stan Wawrinka are among the stars slated to play this year, but it’s also fun catching rising players on the side courts, where you can sit close and see just how fast those blistering aces really are.

Emmy-winning choreographer Comfort Fedoke of “So You Think You Can Dance” and Michael Mindlin, a dance supervisor for “Hamilton,” are among the big names making appearances. The night is capped with an outdoor concert starring the Afro-Colombian sounds of the Soukous All Stars and Bazurto All Stars.

Kesha and Macklemore at Jiffy Lube Live: Pop explorer Kesha and cornball rapper Macklemore are touring in support of new albums that turn tumult into inspirational, feel-good fist-pumpers. Amid her ongoing legal battle with former producer Dr. Luke, whom she accused of physical, sexual and emotional abuse, Kesha released the self-affirming “Rainbow.” Macklemore’s public struggles pale in comparison to Kesha’s, but he took a similar approach on “Gemini,” a breezier pop-rap record than his last.
