Search Results: ties me up

Of course if they played an odd number of games, somebody must lead, since tennis matches always produces a winner. I was curious as who leads or what is the all-time series between the Williams sisters in tennis. Any idea. I think Venus leads by around 7 or 8 games but can't recall. I lazily saw something about this during a Wimbledon event. Many times these women face off against each other in rounds as they are at same event and both tend to advance deep, although not as deep lately as when younger. Both women are in their late 30s.

Please vote and guess and look up the answer and compare. Don't cheat, please! Is it 17-17, 22-22, Venus 18-13, Serena 20-16 or what. I really can't even think how many times they have faced off. Maybe around 35 is my guess. Please share your answer! Please tell if you were close after looking it up but don't tell the answer since others will be giving opinions and likely will read it before they post or vote!
