Vaughn will start at first base and bat sixth in Monday's game against the Padres.
Vaughn had been briefly overtaken by Jake Bauers as the Brewers' primary first baseman, but it will be Vaughn holding down first base Monday for the fifth time across the last seven contests. The 27-year-old Vaughn is slashing .415/.458/.561 in September, though he's yet to go deep this month.
