Adam Dunn knew No. 400 was coming. He just wanted it to mean something.

For a few brief moments, it did.

Dunn launched an 428-foot, opposite-field blast into the Kauffman Stadium fountain with Kevin Youkilis on first base in the eighth inning to bring the Sox to within a run. But after Brett Myers retired the first two batters in their eighth, they reeled off four straight hits, including a three-run blast by Mike Moustakas to put the finishing touch on a 9-4 victory.
