Seattle Mariners at Colorado Rockies
Seattle's Bryce Miller takes the mound with an ERA of 4.19 and a WP-calculated FIP of 4.62 over approximately 107.3 innings pitched this season. He's opposed by Colorado's Jose Quintana, who carries a higher ERA of 5.27 and a higher FIP of 5.41 across roughly 41.0 innings pitched. On these figures, Miller's marks are the stronger of the two, giving Seattle the more reliable arm on the mound tonight.
Looking at the team-wide numbers, Seattle's offense shows a WP-estimated wOBA of 0.304, while Colorado's offense grades out higher at 0.321. On the pitching side, though, Seattle holds the better team ERA at 4.21 and FIP at 4.07 compared to Colorado's ERA of 5.61 and FIP of 4.92, both of which favor the Mariners' run prevention over the Rockies'.
A handful of injury statuses are on record for this matchup. Tyler Bell of the Rockies is listed with a status of 'Out,' while Brody Brecht and McCade Brown of Colorado are both listed on the 60-Day IL. For Seattle, Matt Brash, Nick Davila, and Brennen Davis are each listed on the 60-Day IL. Taken together, the pitching numbers on both sides of the ball lean toward Seattle, even with Colorado's edge in team offensive wOBA.
