The Detroit Tigers are fighting for their playoff lives on Wednesday afternoon, as they trail the Seattle Mariners 2-1 in this best-of-five series ahead of Game 4.

The Tigers were largely dominated in Game 3 after splitting the first two on the road, as the bats simply died and allowed the Mariners to take a commanding 4-0 lead which they maintained until a minor rally in the 9th inning.

If Detroit doesn't find a way to fix their offense, they likely could be playing their last game of the season this afternoon. But with everything on the line, manager A.J. Hinch is keeping things the same in his lineup.

Prediction for Game 4 in Detroit

The Tigers have had a knack for surprising fans all season long, even when things have felt the lowest. Being able to knock out their hated rivals on the road last round even after handing them the division in historic fashion was a great moment.

Things won't end just yet, as Mize will do enough on the mound to keep Detroit in this game while the bats wake up enough to get them into the winner's circle to force a decisive Game 5.

Prediction: Tigers 7, Mariners 3
