(Rafa's just not feeling it in his fight against Federer.)
So I'm already a little behind, but here's how the groups were ranked at the end of the 2nd Round of Round Robin:
2-0 David Ferrer - ESP
1-1 Novak Djokovic - SRB
1-1 Jurgen Melzer - GER
0-2 Andy Murray -GBR / Janko Tipsarevic SRB
2-0 Roger Federer - SUI
1-1 Our Hero, Rafael Nadal ESP
1-1 Jo-Wilfried Tsonga - FRA
0-2 Mardy Fish - USA
You will note that Murray did in fact leave the competition due to injury and Tispsarevic took his place. Tip than lost to Melzer. So he inherited a losing record and did nothing to improve it. Group A is still a bit of a toss up though. I think if Novak beats Tip and then Melzer beats Ferrer. that would put them all at 2-1 and then I'm not sure how they rank them by points to figure out who makes it through.
Nadal needs to beat Tsonga to move to the semis. I think this is a tall order. Rafa got so totally handled by Fed in their match up. Rafa says it's not injury or illness that contributed to the lopsided loss. I just don't think it's in the cards this year. But we'll see soon enough! Vamos!
