The fact that Kerber didn't tank against Keys (which would have taken out Cibulkova as it happened) when she was assured of the semis proves that she had tried her best in every match. Kuzzie's last group match against Muggie may or may not have been a little bit of a tank, although I can't fault her for that one since she had played so much tennis leading up.
Looking at the WTA top 10, top 20, top 50, the big tall girls, 6 ft Amazon types, have their place but are not dominant in any of those ranking categories. Like I said, all four semis here are four of the best runners atm. It is now all about running and rallying and working the rally until you find a winner, meaning you really need to get to work on all parts of the tennis book. Cibulkova as a player for example is nothing like what she was when she was losing to Woz back in 2011 AO. She wasn't playing those slices, droppers, lobs, and volleys then like she did against Kerber in both their matches here.
I think Kerber and Li Na have about similar power levels although Li is much more of an attacking player and Kerber is the counter attacker and more of a defender. I am not sure who is the better of the two in both game and achievements, they are very comparable.
Cibulkova served 67% of first serves against Li in their 2014 AO final which Li won 7-6, 6-0. Cibulkova only had 11-28 winners/UFE. This time round in the Kerber final she was at a staggering 83% first serves and 28-14. She had no way to afford slacking her of level in play at any point in the match, she had to redline, overdrive from start to finish to beat Kerber. Just couple of points here and there in the second set, say when Cibs was serving for the match when Kerber had bps, if they had gone Kerber's way would have totally changed the momentum and it is hard to ask Cibs to keep playing that way if it had gone to a third set seeing that at the end her serve was beginning to DF. (She served 7 DF against Li in 2014 AO).
This is the same with Radwanska, although Radwanska plays a completely different game. Players like Radwanska, Cibulkova don't have any margin for error at the elite of elite level, like QF, SF, Final level at Grand slams or YEC matches. Radwanska played a brilliant match to defeat her nemesis Azarenka in the 2014 QF, promptly lost to Cibulkova 1 and 2 in the semis. Just like this time, although it was the WTA semi finals against Kerber. Radwanska plays a very very intricate game to win her matches. It takes super physical concentration and mental concentration. None of her points come easily. She doesn't get blown away by power (except against one person) so much as that style may unravel because it is difficult to sustain such a game against several elite opponents in a row.
So I am completely fine with the RR format as it stands. It should be different from slams and regular tournament. It should allow a second chance. Going 1-2 in RR but coming back to win the whole thing just proves how tough the competition is. I am completely happy for Cibulkova winning her YEC as I was for Radwanska last year. They both fully earned their wins. It just wouldn't be right if these two ended their careers without a big title, although not a slam, the next biggest. This was a great tourny. Serena is/was far too great to allow the others reward for the work and talents, but even Serena has to slow down for others to take their place too. The other one, the banned person, I didn't miss here. The only person missing really was Azarenka.
