I wouldn't call Dementieva a big match player either, probably more of a bottler actually.
agreed but for me she is more able to reach finals of big events. however, the winner of the us open will be between serena and safina. the way safina has been playing on hard she deserves it most imo.
Dementieva should beat Jankovic. It will not easy, with many breaks (of course), but Dem' will reach final.
Between Safina and Williams, i would bet on Serena. The crowd could affect Dinara a lot and if Serena is 1 or 2 m inside court when Safina will do second serves, we can predict something like 15+ dfs from Safina.
