Mariners vs Tigers Prediction
Detroit was blown out on Friday to open this series, but they have been elite at bouncing back after a loss this season. The Tigers are 32-16 at home this year, while the Mariners are 24-24 on the road. Seattle has lost three of their last four and they are starting Kirby, who has allowed one earned run or fewer in three straight. Detroit is going with Mize, who has allowed two earned runs or fewer in five straight starts. This should be a fantastic pitching matchup, but I have to side with the Tigers to bounce back at home.
