Introduction

More MLB picks: Colorado Rockies · Seattle Mariners

Seattle Mariners’ surge is undeniable, winning 9 of their last 10 while averaging 6.5 runs per game, and that offensive rhythm defines this MLB prediction. Colorado enters with only 2 wins across their last 10, scoring just 3.0 runs per game in their most recent 5, a clear indicator of inconsistency. With a cross-league matchup between the American League Mariners and National League Rockies, the statistical gap in both form and production sets up a decisive betting edge toward Seattle and a game script that leans heavily toward runs clearing the total.

Team Analysis

Colorado Rockies

The Rockies’ 43-114 record reflects season-long struggles, and their 2-3 mark in the last 5 games with just 3.0 runs per outing confirms the lack of consistent offense. Hunter Goodman’s power has been a rare bright spot, but the overall lineup has failed to sustain rallies on the road. With an 18-59 away record, Colorado Rockies’ lack of rhythm outside of Denver continues to be a liability for bettors backing them.

Across the last 10 games, the Rockies have gone 2-8 while averaging 4.0 runs, a sign that production spikes have been isolated rather than sustained. Mickey Moniak provides some middle-order stability, yet the team’s inability to cash in runners has left them vulnerable late in games. Jordan Beck has chipped in offensively, but without consistent situational hitting, this group remains an unreliable road side against higher-caliber opponents.

Seattle Mariners

Seattle arrives in peak form with a 5-0 record in the last 5 games, producing 6.0 runs per contest and dominating at the plate. Cal Raleigh’s power has been the centerpiece of that surge, consistently driving in runs and setting the tone for the lineup. With a 50-27 home record, the Mariners have translated their offensive rhythm into a consistent betting edge at T-Mobile Park.

The broader 9-1 stretch over the last 10 games makes clear sustained momentum, with scoring output at 6.5 runs per game. Eugenio Suarez has been a critical run producer, complementing Julio Rodriguez’s ability to generate offense from multiple spots in the order. This balance of power and consistency has made Seattle one of the most reliable moneyline plays in the league during September.

Moneyline Betting Prediction

The Mariners’ 9-1 surge in their last 10 combined with a dominant 50-27 home record positions them as the clear side in this matchup. With Cal Raleigh, Eugenio Suarez, and Julio Rodriguez all contributing run production, and Seattle already holding a 2-0 head-to-head lead, the Mariners are the superior play with both momentum and offensive depth on their side.

Form and matchup edges favor the Seattle Mariners — back them.

Over/Under Prediction

In their last five, the Seattle Mariners have produced 6.0 RPG and the Colorado Rockies 3.0. That output frames how this total sets up.

These teams are combining for 9.0 runs per game recently — above the posted total of 8.0. That points toward the Over 8.0.
