Li amazed by weary Serena's revival

After losing to Serena Williams in the final of the WTA Championships, Li Na says she was confused by how the admittedly tired Williams started the match out so slow and finished so strong.

“So this is the reason why she lives in Los Angeles, right?” Li joked, possibly referring to Hollywood’s population of actors. “No, I mean, I don’t know—I don’t know what happened with her—but when she started the match, she’s already feeling like [she's going to] die. But in the final set, she can serve 180 [K.P.H.], 190 [K.P.H.]. I have no idea about this.”
