The Padres have played well at home all season and have won 23 of their past 31 games at Petco Park -- the best home record in the Majors since April 24.
"You look at home records of all teams in baseball, it's going to slant toward the advantage of home teams," Padres manager Bud Black said. "It's just the nature of being at home."
Sunday's starter Andrew Cashner has been especially good at home. He enters the finale with a 4-1 record and 2.65 ERA in six starts this season at home.
