Cardinals vs Mariners Prediction
The Mariners are 6-2 in their last 8 head-to-head meetings against the Cardinals, and are 4-1 in their last 5 meetings in Seattle. Over is 3-1 in their last 4 meetings in Seattle.
In this Cardinals vs Mariners Prediction, the Mariners are coming as -230 home favorites. The Mariners have won by 2 runs each of the first two games of this series, and now have Logan Gilbert on the mound, who has been excellent at home, with a 2.15 home ERA. He has just one earned run in each of his last two home starts, while on the flip side, McGreevy has 4+ runs in two of his last three starts for the Cardinals. The Mariners have a better offense to offer Gilbert run support, so I expect them to win by 2+ runs in this one as well.
