The Big Gainer of the week award this week goes to Gilles Muller. He was the 6th seed at Sydney, and won the tournament with a win over Pablo Cuevas among others. This title gave Gilles 38 ELO rating points, and he gains 4 places in my rankings to #22.
The Upset player of the week this week is David Ferrer. He was the 3rd seed at Auckland, but after a bye to the 2nd round, he lost his opening match. This loss cost David 14 ELO rating points, and he falls 2 places in my rankings to #26.
Other strong performers relative to their rankings are Daniel Evans, Joao Sousa, Robin Haase and Jordan Thompson.
