After 162 games and seven more in the playoffs, the Detroit Tigers' season comes down to one night in Seattle — with their ace on the mound and a trip to the ALCS on the line. Friday's decisive Game 5 starts at 8:08 p.m. EST at T-Mobile Park, with coverage on FOX.
Tarik Skubal, a Seattle native, gets the ball for the Tigers (87-75) and looks to build on a stellar postseason in which he's struck out 23 over 14.2 innings with a 1.84 ERA. The left-hander will pitch just a few miles from where he grew up, facing a Mariners lineup that's already given him trouble this season. He allowed seven runs in 10.2 innings against Seattle during the regular season, including a homer in each outing.
The Mariners (90-72) will send out George Kirby, who threw five strong innings in Game 1, with veteran right-hander Luis Castillo also available. In two appearances against the Tigers this season, Kirby gave up six runs and 11 hits in 11 innings, also allowing a home run in each start.
The Tigers forced the decider with a 9-3 comeback win in Game 4, sparked by Riley Greene's three-run homer and Spencer Torkelson's four-RBI night. A win would send Detroit to its first ALCS since 2013.

Tigers vs Mariners Predictions and Picks
"Skubal had a sparkling 2.21 ERA this season, but he would've kept it under 2.00 (1.99, to be exact) had he not pitched against the Mariners. He allowed seven runs in 10.2 innings of work against the Mariners, with a home run in each game. Seattle won both of those games, and it also stole Game 2 when the Tigers could've taken a commanding series lead .... Skubal is the better starting pitcher, but the Mariners have his number and the depth to get it done at home. If you want to play it safe and think it could be close, I don't hate taking the Mariners." — Ryan Gilbert, Sports Illustrated
"One thing you can probably book in Game 5: Andres Munoz standing on the mound in the bottom of the ninth. The baddest reliever on either side was stretched thin in the first three games, pitching in all of them and racking up a spotless two-inning appearance in their 11-inning Game 1 loss. Probably a blessing in disguise that Game 4 turned into a blowout, giving Munoz a breather .... Yet if called upon to protect a slim lead, will opponent familiarity or fatigue dog him...? Doubt it .... If Munoz's tank is at least half full, he could be the difference maker in what should be a close and tight game late. Prediction: Mariners 4, Tigers 3." — Gabe Lacques, USA Today
