Cincinnati’s most significant advantage is its offensive production compared with Seattle. The Reds have the higher batting average, more runs, more hits, more home runs, a slightly better on-base percentage, and a higher slugging percentage. Cincinnati has hit nine more home runs and scored nine more runs than the Mariners. The major concern is the pitching staff, which has issued 180 more walks and carries considerably higher ERA and WHIP figures.
Seattle Leans on Its Pitching at T-Mobile Park
Seattle comes into Monday’s contest with a 49-50 overall record and a 28-21 record at home.

The Mariners also recently recorded an 8-2 road victory over Tampa Bay but lost the other two games in that stretch by scores of 6-1 and 7-2.

Seattle has also produced a 20-16 record in day games.

Cincinnati Reds vs Seattle Mariners Picks and Prediction
Cincinnati Reds vs Seattle Mariners Pick
- Pick: Seattle Mariners Moneyline
Seattle is my moneyline pick for Monday’s matchup. Cincinnati holds the advantage in every supplied offensive category, but those differences are relatively narrow in runs, hits, home runs, and on-base percentage. Seattle’s pitching advantages are more pronounced, particularly its lower ERA, lower WHIP, greater strikeout total, and significantly smaller walk total. The Mariners are also seven games above .500 at home, while the Reds are three games below .500 on the road. ESPN Analytics gives Seattle a 59.5% chance of winning, supporting the Mariners as the preferred side.
Cincinnati Reds vs Seattle Mariners Total Pick
- Pick: Under 8.5
Take the under if the total is set at 8.5. I am taking the under because Seattle enters with a 3.62 team ERA and a 1.18 WHIP. Three of the Mariners’ last five games have produced exactly seven combined runs, and Seattle has held two of its last three opponents to three runs or fewer. Cincinnati’s scheduled starter carries a 4.11 ERA, which is lower than the Reds’ team mark. With Seattle’s strong pitching statistics and several recent lower-scoring results, I expect this game to remain below the suggested total.
Final Score Prediction: Seattle Mariners 5 – Cincinnati Reds 3
