Team Analysis
Colorado Rockies
The Rockies continue to labor through another difficult season, showing a 2-3 record in their last five games and 3-7 across their last 10. Their offense has been inconsistent, averaging 4.0 runs in the last five, which has not been enough to offset a pitching staff that regularly puts them behind early. Hunter Goodman’s power has been one of the few bright spots, but overall production has not traveled well.
Colorado Rockies’ road record of 18-58 speaks to their lack of competitiveness away from home, making them a risky side for bettors. Mickey Moniak and Jordan Beck have flashed offensive potential, yet the lineup often struggles to string together sustained rallies. Until the Rockies show durability in scoring on the road, they remain a fade against a surging opponent.

Seattle Mariners
The Mariners have caught fire at the right time, winning all five of their last five contests and nine of their last ten. Their offense has been steady, producing 5.8 runs per game across the last 10, powered by Cal Raleigh’s consistent run production. This surge has been complemented by a strong 49-27 home record, giving them a reliable edge in front of their fans.
Julio Rodriguez’s balanced hitting and Eugenio Suarez’s power presence have provided depth, ensuring the Mariners aren’t relying solely on one bat. Their pitching stability combined with reliable run creation makes them a complete package that overwhelms inconsistent opponents like the Rockies. With momentum, home dominance, and lineup depth all aligned, Seattle stands firmly as the moneyline side.
