SF:  (WC) Kristie Ahn & Kaitlyn Christian (USA/USA) UNR vs (3) Jos Rae & Anna Smith CR 230 (114+116)

On the face of it, an excellent chance of a place in the final for Jos & Anna, but the Yank wild cards have taken out two pairs with a CR in the 400s (Hibino & Hozumi [CR 423] in three in R1 & Cako & Pluskota [CR 434] in their QF, also in three).  Kristie Ahn currently has no doubles ranking, hence the "UNR", but her CH was 448 in 2010, while Kaitlyn Christian is currently ranked 1098, but has a CH of 524, also in 2010.  Here's hoping Jos & Anna will have just a bit too much for them.  

Ahn has just graduated from Stanford finishing at 4 in singles and 13 in dubs (playing with carol Zhao) in the college rankings. Christian has just graduated from Southern California and finished unranked in singles (only top 125 players are ranked) and 31 in dubs (playing with Sabrina Santamaria).  They probably know their way around a doubles court.
