Cleveland comes into this matchup with a 42-39 overall record and a 19-17 home record. The Guardians have recently won over Chicago 4-3 in 10 innings after losing to Chicago by scores of 2-1 and 6-5.

Cleveland’s pitching staff has recorded 739 strikeouts, which is higher than Seattle’s total, while also limiting opponents to a .237 batting average. Although the offensive numbers trail Seattle in several categories, the combination of strikeout production and a slightly better overall record gives Cleveland a solid foundation at home.
Seattle Mariners vs Cleveland Guardians Picks and Prediction
Seattle Mariners vs Cleveland Guardians Pick
- Pick: Cleveland Guardians Moneyline
Cleveland is my pick because the Guardians have the better overall record, the stronger home record, and the matchup predictor favors them with a 59.0 percent chance compared to Seattle’s 41.0 percent. Cleveland also has the edge in the listed starting pitcher based on record, ERA, and strikeouts. While Seattle has stronger overall team pitching numbers, the combination of home field and the matchup predictor gives the Guardians the advantage.
Seattle Mariners vs Cleveland Guardians Total Pick
- Pick: Take the under if the total is set at 8.5.
I would lean toward the under if the total is set at 8.5 because both teams have season ERAs below 4.00 and have generally relied on pitching more than offense. Seattle owns a 3.69 ERA and Cleveland sits at 3.79, while both clubs have been held to three runs or fewer in several recent games. Based strictly on the provided information, I expect this to be a lower-scoring contest.
