Mariners vs Rockies Prediction: Mariners -212

The Seattle Mariners are heading into this game with an impressive 89-69 record, while riding a six-game winning streak. In contrast, the Colorado Rockies have struggled throughout the season with a 43-115 record and are currently on a two-game losing streak. The Mariners have been dominant at home with a 50-27 record, indicating a strong likelihood of success at T-Mobile Park.

The Rockies’ pitching struggles are evident with Bradley Blalock starting, who carries a 9.16 ERA and a 1.82 WHIP. The Mariners’ lineup, featuring players like Cal Raleigh, who has joined the 60 home run club, should have an edge against such vulnerable pitching. Additionally, the Mariners have consistently outscored the Rockies by an average margin of four in recent meetings.

Seattle’s overall performance this season, particularly at home and against weaker opponents, further solidifies their standing as favorites. They have a winning percentage of 64.9% at home and have fared well against league opponents with a 50.0% record. With the stakes of maintaining their division lead, the Mariners have added motivation to secure another victory.
