Brewers vs Mariners Prediction: 'Under 8.0'

The Brewers have been strong at home with a record of 41-22, but they also demonstrate a tendency for games to finish under the total. Their home games have resulted in an over/under record of 26-37, indicating a higher probability for lower-scoring outcomes.

The Mariners are struggling on the road with a 26-37 record, and their offensive stats rank in the lower half of the league. Combining this with the Brewers' formidable pitching, it seems likely that the Mariners will find it challenging to put up significant runs.

Probable starting pitchers Bryce Miller for the Mariners and Kyle Harrison for the Brewers both have respectable ERAs below 3.50, which could contribute to a tight, low-scoring game. Both teams' recent performances reinforce the possibility of the total staying under 8.0 runs.

Taking into account all these factors, the game is projected to end with a score of Brewers 4 - Mariners 2, supporting the under 8.0 pick.

• Brewers vs Mariners Prediction: 'Under 8.0'
• Brewers vs Mariners Score: 'Brewers 4 - Mariners 2'
