Mariners vs Tigers Prediction 

Detroit looked like they were going to lose both games at home to lose this series, but they woke up in the fifth inning of game four to steal the win. The Tigers found offense out of nowhere and now have all of the momentum coming into this game. Detroit is starting Skubal, who has allowed two earned runs or fewer in eight of his last nine starts. Seattle is going with Kirby, who has allowed two earned runs or fewer in four straight. This is a great pitching matchup, but I have to side with Detroit here.
