No love for Serena? 20 GS singles titles?

Well, he (she?) probably meant 'best male player'.

But if you want to compare them on pure tennis ability, head to head, Serena would have no chance of taking a set off of Pete :)

Yeah, of course, but surely she's in the "player pool" :)

I meant male US tennis player. But even Serena turned pro in 1995 when Sampras was still at his peak. And she was an instant phenom. So by that measure even though she is still playing now, I always considered Serena to be from that "era" in a way.
