Alfonso Soriano 4 Carlos Lee 1

Soriano is smoking in the sixth spot, especially after a walk-off slam!

Carlos Lee might have hit the longest home run of the night. But Alfonso Soriano hit the most important one.

Long story short, it bailed out Lou Piniella's questionable managing and Mike Fontenot's poor execution. But a win is a win is a win. And by the slimmest of margins, the Cubs are still in first place.
