How great was this year’s U.S. Open?

First, prohibitive favorite Serena Williams melted down like Chernobyl in the women’s semifinal, which ushered in Komeback Kid Kim Clijsters’ women’s final win over crafty Caroline Wozniacki.

Then prohibitive favorite Roger Federer melted down much more meekly in the men’s final, falling to the Big Argentine Juan Martin del Potro, who in the end out-manned Federer.

Sweet . . . and sweet.
