Mariners vs Brewers Prediction

The Brewers are 8-2 in their last 10 meetings against the Mariners and are 3-1 in their last 4 meetings in Milwaukee.

In this Mariners vs Brewers Prediction, the Brewers are coming as -150 home favorites. I like the Brewers at home in this one, as Bryce Miller has been in very bad form for the Mariners. He has given up 4+ runs in three of his last four starts and has been weaker on the road, with a 4.47 ERA and the Mariners have been terrible against lefties lately with just 1.5 runs per game in their last 10. Kyle Harrison has been elite at home with a 6-1 record and 1.38 ERA and I expect him to lead the Brewers to a home victory today.
