The 13-time major champion adds that she feels "really 100 percent" committed to tennis since returning last year following a series of health scares. She's also thrilled to have her older sister Venus competing in Paris, too, after being diagnosed with an autoimmune disease. Says Serena: "Everything that she's doing is so inspiring for me."
