| Pablo Cuevas, © Brasil Open 2015 |
This week, our Upset player of the Week is Tommy Robredo. This is the 2nd time he's won this award, I'm not sure whether it's bad luck or a real drop in form, but when you get a bye in to the 2nd round, you're expected to win your 1st match. His loss this week led to him losing 12 ELO points and falling 3 places in the rankings to #25.
Other strong performers relative to their rankings are Donald Young, Sam Querrey, Austin Krajicek, Joao Souza and Sergiy Stakhovsky.
