Serena is very dominant atm.
She is VERY hard to beat. Almost impossible once INTO a tournament.
She won Wimbledon without losing a SET.
Served 41 Aces and only 10 DF.
Won 81% of points on her 1st serve across the tournament.
Serena has been able to beat most other top 20 players whilst playing at about 70% of her best. If threatened she can then raise her game a further one or two levels, hitting even harder, and more consistently, and retain her accuracy.
Her on-court persona is very dominant, confident and aggressive.
So Serena has both Physical and Mental strength.
I'd place a good player's chances of beating Serena on any given day as about 20:1 against.
