Tigers vs Mariners Prediction
The Mariners are 4-1 in their last 5 meetings against the Tigers, but the Tigers are 3-2 in their last 5 visits in Seattle. Over is 3-1 in their last 4 meetings.
In this Tigers vs Mariners Prediction, the Tigers are coming as -135 road favorites. The Tigers drew first blood in Game 1 and broke the Mariners’ home court advantage and managed to take the lead in the series with a bullpen game. They are now putting Skubal on the mound, who has been one of the best pitchers in baseball, and he has been in excellent form lately, with just one earned run in each of his last three starts. On the flip side, Castillo has been elite at home for the Mariners, with a 2.60 home ERA, and he is also coming in excellent form, with just three earned runs across his last four starts. Both teams are weaker against the opposing starter throwing hand, so I like this game to stay low-scoring. Take the under 6 runs.
