At home, you go for the win and the closer (Owens) would throw in the 9th in a game that is tied or if the fish had the lead. Julio warmed up due to the fact in case Nomar's at bat came up, he would pitch to the righty and not have Pinto face the right handed hitting Nomar!
In away games, the closer will only throw in the bottom of the 9th with a lead or in a later inning like if the fish go up in the 10th or 11th and etc.
