London • There are moments in which nothing at all seems different about Serena Williams, moments such as when she unleashed a 109 mph service winner to even her Wimbledon quarterfinal at a set apiece, leaned forward and yelled, loudly as can be, “Cooome ooon!”
Or when, about 10 minutes later, she stretched for a lunging backhand winner to break at love and take control of the third set, then raised a fist, figuring a berth in her 11th semifinal at the All England Club was close at hand.
And after Williams came up with a comeback to beat 52nd-ranked Camila Giorgi of Italy 3-6, 6-3, 6-4 on Tuesday, she headed off Centre Court with her right index finger aloft.
