Which Grand Slams finals were most lopsided? And why?

One came to mind real quickly, in the womens game, it was Steffi vs Zevereva. Zev was to be the next big thing at the time, but went on to lose 6-1 6-0 I believe, and though she had a decent singles career, she was more known for her doubles. This was due I think to not just nerves in a major final, but the pressure from the media, her country , peers, and so forth which is why she did much better in doubles. It is easy for us, as fans to criticize players for their lack of play, but when on court and in a big match, you tend to tighten up, spray around and cant find the game that got you there. That is why only handfuls are considered the very best cause they can stay in control of their emotions match in match out.
