When there was still hope of getting Infante back to action after the All-Star break, his presence looked like a potentially big factor for the Tigers against White Sox lefties Chris Sale and Jose Quintana. They'll pitch the first two games of the upcoming series.
Instead, rookie fill-in Hernan Perez will likely get the starts.
Leyland didn't want to make excuses for his team's struggles out of the break, but he also didn't want to sugarcoat the lineup without Infante.
"We miss Omar," Leyland said. "He's a good big league player and our regular second baseman."
