Re: Kim for POY?
Well let me blurt out some info here.
Serena won two slams at AO & Wimby, made the quarters at the FO (her only other slam appearance apart from those 2 other slam wins) & had a 25-4 win loss record (86%). That is impressive for someone who has only played 6 events this year. However she didn't play for the rest of the year after Wimby (not her fault by any means) & her performances at the 3 non-slam events she contested weren't fantastic, but decent (Sydney RU, Rome SF & Madrid 3R).
Kim won the USO, the YEC (second biggest to the slams with only the best eight playing there), Miami (big non-slam event), Cincinnati (not as big as the other three, but still big) & Brisbane - so five title, three more than Serena. Other two slam performances were somewhat just a bit above average - Wimby QF & AO 3R. She did make the quarters of better at eight of her eleven events she played & had a 40-7 win loss record (85%).
Considering those stats, they are impressive in many different ways. Even though Serena did win two titles for 2010, they were the ones they carry a lot more historical importance & weight. However Kim won one of those as well too & the YEC, which if not more important than the slams is a close second. A GS & YEC plus Miami & Cincinnati are either on equal par with Serena's two slams or just slightly close from equalling the prestige.
I could think of a lot more reasons for who should be player of the year & it was difficult to pick between the two. I'm going to give it to Serena, but only just - because her two slams only by a fraction (5-10%) outweigh Kim's 5 titles. However I have a feeling that the ITF will either pick Kim or Caro, & the WTA will pick either Serena or Kim. I mean the ITF picked Hingis in 2000 & she didn't a slam, but was year-end No.1 & was super consistent & the WTA picked Venus & she won two slams & an olympic gold & was on a 30+ win streak at one point.
