But Athletics owner Lew Wolff doesn't expect the series to come down to that.
Wolff told USA Today Sports that he thinks the Athletics will win Game 4 at Comerica Park on Tuesday and reach the ALCS for the first time in seven years.
"I'm confident we don't have to go back to Oakland," Wolff told USA Today Sports. "I think we're going to win it here."
The Athletics belted three home runs Monday en route to a 6-3 victory in Game 3.
The Athletics, who won their second straight AL West Division title after going 96-66 this season, have not reached the ALCS since 2006 -- when they were swept by the Tigers. They have not won the World Series since 1989.
Oakland had a better record than Detroit (93-69) this season, but it was the AL Central-champion Tigers who entered this series with the big names and the big payroll.
Now Detroit needs two straight wins to extend its season.
Wolff, who has come under fire recently for attempting to relocate the franchise to San Jose, told USA Today that Monday's victory was the "biggest" of his career.
The 78-year-old Wolff also said that winning a World Series would be the thrill of a lifetime.
"This was the biggest win I've ever had as an owner," Wolff said. "If we win the World Series, it would be the greatest thrill of my professional career. Nothing comes close. I can't even imagine that feeling."
