One strength for Seattle entering this matchup is pitching consistency. Despite the offensive inconsistency, the Mariners have maintained one of the better ERAs in this game. Seattle has also shown the ability to limit damage defensively during victories, including allowing only one run in a recent win over Chicago.
Kansas City Trying to Snap Losing Streak
Kansas City enters this matchup with a 20-30 overall record and a 13-13 home record. The Royals recently lost to Boston three straight times by scores of 4-3, 7-1, and 3-1 after previously recently won over St. Louis 2-0. Kansas City also recently lost to St. Louis 4-2 before that victory. The Royals have struggled offensively throughout this recent stretch, scoring three runs or fewer in four of the last five games.
The Royals are batting .237 as a team with 194 runs scored, 392 hits, and 48 home runs this season. Kansas City owns a .314 on-base percentage and a .382 slugging percentage while carrying a 4.29 ERA and a 1.38 WHIP. The pitching staff has recorded 419 strikeouts while allowing opponents to hit .244 against them.
Kansas City’s biggest issue entering this matchup has been run production. The Royals are averaging fewer runs than Seattle and have struggled to generate offense during the recent losing streak. Facing a Seattle pitching staff with a 3.64 ERA creates another difficult challenge offensively.
Seattle Mariners vs. Kansas City Royals Picks and Prediction
Seattle Mariners vs. Kansas City Royals Pick
- Pick: Seattle Mariners Moneyline
Seattle enters this matchup with the stronger pitching numbers overall and also holds a slight edge in the matchup predictor. The Mariners have the better ERA, WHIP, and strikeout total entering this contest while Kansas City has struggled offensively during the recent three-game losing streak. Seattle has also shown flashes offensively recently and should benefit from facing a Royals staff carrying a 4.29 ERA.
Seattle Mariners vs. Kansas City Royals Total Pick
- Pick: Under 8.5
I like the under because both offenses have been inconsistent recently, especially Kansas City. The Royals have scored three runs or fewer in four of the last five games, while Seattle has also played several lower-scoring contests lately. The Mariners bring a solid 3.64 ERA into the matchup, and the recent results for both teams suggest another game where pitching could control the pace.
Final Score Prediction: Seattle Mariners 4 – Kansas City Royals 3
