If tipsarevic wins, then Fed and Delpo heads the group with 2 wins each. As Delpo just beat Fed, he goes through as group leader to play Andy next.
If Ferrer wins in 3 sets (tipsy won 1st set) then 3 players head group b with 2 wins each and the position is as followed
Position. Player. Set win. Set loss. Percentage set win
1. Fed. 5. 2. 71.4%
2. Delpo. 5. 3. 62.5%
3. Ferrer. 4. 4. 50%
In this scenario, Fed wins the group and plays Andy next.
I am hoping that Ferrer wins his match so Andy gets to play Fed. I feel that Andy has found a way to beat Fed recently and will come into the match with more confidence. Andy is more focused when he comes into a match as a lower ranked player (against Fed, Nole or Nadal), and especially against Fed the GOAT
. This is when Andy plays his best tennis.
