Mariners vs Blue Jays Prediction

The Blue Jays are 3-1 in their last 4 meetings against the Mariners, but the Mariners have won their last three visits in Toronto. Over is 7-2 in their last 9 meetings.

In this Mariners vs Blue Jays Prediction, the Blue Jays are coming as -135 home favorites. The Mariners drew first blood in the series and got both the lead and stole the home court advantage. They are now putting Gilbert on the mound, who has been elite this season, and coming into this matchup in excellent form, with a 4-1 record and 2.30 ERA across his last 5 starts. Yesavage is also coming off back-to-back shutouts for the Jays, including 5.1 runless innings with 11 strikeouts against the Yankees in the ALDS Game 2. Yesterday’s game had just 4 total runs, and I expect both today’s pitchers to suppress the opposing offenses. Take the under 8 in this one.
