I didn't think Kerber would win really, but I was utterly bemused by the talk (not just from VCS) that the semi meant we wouldn't get a competitive match.
I mean Vika is getting to be the most over-rated person in tennis, something like 11 ESPN people went for her to win the Tournament based on winning Brisbane for her first title in well over a year. Yeah she's giving Serena some fun matches recently, more than say my fave player, but she still manages to lose. 3-17 isn't a great record, Kerber had 1-6, it's not a big difference.
Apart from Lisicki being quite frankly weirdly inspired at Wimbledon, recently Kerber fits the pattern of beating Serena much better than Vika, she retrieves brilliantly, uses a lot of variety and makes Serena play more than she wants. Vinci and Cornet, whilst the likes of Timea gave her tough games.
Having said that Serena normally still wins easily, so kudos Kerber.
