Vaughn's offensive production has improved in the week since the Sox called up first base prospect Tim Elko — and it's not because Vaughn is feeling the pressure, he says.

Tim Elko collected his first MLB hit — a go-ahead three-run home run — to lead the Chicago White Sox to a 4-2 win over the Miami Marlins on Sunday.

Tim Elko’s first big league hit was a homer. And a decisive one at that. Elko’s three-run shot in the bottom of the sixth inning put the Chicago White Sox ahead to stay.
