Here's another comparison of Roger's dominance:

He's made 18 straight GS semis (as Royce mentioned earlier). The entire Russian women's entourage (Dementieva, Sharapova, Kuznetsova, Safina, Chakvetadze, Zvonareva, and Petrova have all made at least one and have been in the top 10 over the streak) have only made 17 of the last 18 semis.
