it's anybody's game

An interesting situation unfolded in the National Scrabble Championship in the US.

After 27 rounds the first 5 players are on 19 wins, the next five players are on 18 wins, the next five are on 17 wins and the next 10 players are on 16 wins. 

This means that with 4 rounds to go any of the 25 players still stands a chance of becoming the US champion.
UPDATE:
1. As Wojtek pointed out to me this last sentence cannot hold true because top players will always be matched against each other in the final rounds in accordance with the rules of king-of-the-hill system.
Nevertheless the situation was very interesting :)
2. Nigel Richards won the NSC 2011:)
3. Zbigniew Wieckowski took 4th place in Division C.
