The Seattle Mariners, 6-1 in their last 7 games against the Cincinnati Reds, find themselves in favorable position to cover -1.5 runs in Monday’s series opener at T-Mobile Park.

Current Form:

The Cincinnati Reds came away with a series win over the Colorado Rockies after taking 2 out of 3 games. The Reds have pumped up 5.2 runs per game over their last five games. Unfortunately, their ERA in this five-game stretch has inflated to a dismal 6.34.

Meanwhile, the Seattle Mariners have won 3 of their last 4 games after losing five games in a row. Seattle’s 3.4 runs per game over the last five games remains mediocre at best. Regardless, they are at least finding ways to win ballgames by banking on their pitching staff, which has posted a rock-solid 3.60 ERA over five games.

Starting Pitchers: Reds LHP Andrew Abbott (5-5, 4.11 ERA) vs. Mariners RHP George Kirby (7-8, 3.11 ERA).

The Matchup: The Mariners have won 6 of their last 7 meetings with the Reds. Seattle also won by two runs or more in each of these victories.

Our Seattle Mariners vs Cincinnati Reds Prediction

The Difference Maker: George Kirby has commanded a 3.09 ERA over his last five games. In his first meeting against the Reds, Kirby surrendered two runs over six innings in a 9-3 win on April 15, 2024.

Reds’ Abbott has lost his last three starts. In his last five outings, Abbott has posted a 4.62 ERA.

The Mariners average 6.1 runs per game against lefty pitchers over the last five games. The Reds are not bad either, scoring 5.5 runs per game against lefties.

What to Expect: A high-scoring series opener could take place on Monday. These two teams have been torching left-handed pitchers recently, so fans can expect fireworks throughout the match.

The Mariners are still projected to cover -1.5 runs mainly because they have a bullpen that can foil any Reds’ comeback attempt. Seattle’s relief pitchers have sported a 3.56 ERA this season.

Fearless Forecast: The Mariners 7, Reds 5

Our betting prediction for the Cincinnati Reds vs. the Seattle Mariners: The Mariners -1.5 Runs
