2017 US Open Semi Finals Update

The quarter finals of the US Open is over, and as the semi finals are starting later today, let's take a look at how that impacted my rankings of the players still in.

The current leaders in the Big Gainer of the tournament awards are Andrey Rublev (+48) and Coco Vandeweghe (+49). Rublev is out of the tournament, but will win the award if Rafael Nadal wins the title, otherwise it will go to whoever wins the tournament. Vandeweghe will win the award if she wins the tournament, or if she loses to Venus Williams in the final, otherwise it will go to whoever wins the title.

View my predictions from round 4 for the Men and the Women here, but before the latest rankings, some stats I calculated for the top 150 players:

Men's Rank	± ELO
1-10	-14
11-20	-22
21-50	85
51-100	22
101-150	16

Women's Rank	± ELO
1-10	-23
11-20	53
21-50	26
51-100	-96
101-150	125
