Williams tears up rankings with semi-final win

Serena Williams tore up the rankings as she demolished Victoria Azarenka on Centre Court to book her spot in a seventh Wimbledon final.

The 30-year-old American, ranked and seeded sixth, four places behind her opponent, produced a scintillating display packed with aces and brutal winners to send out the fiercest of warnings to the waiting Agnieszka Radwanska.
