Arizona Diamondbacks at Colorado Rockies
Arizona sends Eduardo Rodriguez to the mound against Colorado's Tanner Gordon in a matchup with a clear gap on the mound. Rodriguez has worked approximately 183.7 innings with a 2.89 ERA and a WP-calculated FIP of 3.95, while Gordon has thrown approximately 100.3 innings with a 6.01 ERA and a WP-calculated FIP of 4.62. Both the earned run and peripheral numbers favor Rodriguez by a wide margin, giving Arizona the stronger arm on paper.
Looking at the team-wide numbers, Colorado actually holds a slight offensive edge with a WP-estimated wOBA of 0.319 compared to Arizona's 0.310. But Colorado's pitching staff overall carries a 5.55 ERA and a 4.90 FIP, both worse than Arizona's staff marks of 4.08 ERA and 4.40 FIP, suggesting the Rockies' run prevention lags behind the Diamondbacks' even beyond the starters.
On the injury side, Arizona has Kyle Amendt and Ryan Bruno listed on the 60-Day IL and Yordin Chalas listed on the 7-Day IL, while Colorado has Tyler Bell listed as Out and both Brody Brecht and McCade Brown listed on the 60-Day IL. Taken together, the pitching figures and team run-prevention marks point toward Arizona as the side better supported by the available numbers, even with Colorado showing a modest edge in offensive wOBA.
