Maria Sharapova might be out of the running for the rest of the season (darn that nagging shoulder injury!), but it hasn’t stopped her from hitting the town — especially in the name of a good cause.

Last weekend she came out to Thousand Oaks, Calif. in full fashion regalia — a green dress from 3.1 Phillip Lim, shoes by Dior, and a brown hyper-zippered Stella McCartney clutch — in support of brothers Mike and Bob Bryan, who’ve taken a page out of Andre Agassi’s philanthropic book with the establishment of their eponymous foundation.

Saturday’s All-Star Tennis Smash raised money for local and national charities supported by the twins, including City Impact, an organization supporting at-risk youth in Ventura County. The half-day event started with a pro exhibition featuring celebs and athletes, including Agassi (in his public playing appearance this year), Jon Lovitz, Jimmy-Jean Louis, Melissa Rivers, Lindsay Davenport, James Blake, Justin Gimelstob, Thomas Blake, and Robby Ginepri.

Afterwards, the brothers feted Agassi for his charitable endeavors at a gala dinner attended by Masha, among others. The evening began with an auction (autographed racquets, days with tennis players) and was capped off with performances by Evan and Jaron and Brandi Carlile.
