Seattle Mariners at Colorado Rockies
Seattle sends Kade Anderson to the mound with roughly 25.3 innings of work this season, carrying a 5.33 ERA and a WP-calculated FIP of 4.51. Colorado counters with Tomoyuki Sugano, who has logged approximately 142.7 innings with a 5.49 ERA and a WP-calculated FIP of 5.57. Comparing the two, Anderson's FIP of 4.51 is lower than Sugano's 5.57, and his ERA of 5.33 is also lower than Sugano's 5.49, suggesting Seattle's starter has been the more effective run preventer of the two so far this year, though Anderson's sample of innings is far smaller than Sugano's workload.
On the offensive side, Colorado's team wOBA of 0.321 sits above Seattle's 0.304, giving the Rockies the edge at the plate by that measure. But Seattle's pitching staff overall shows a lower ERA of 4.21 compared to Colorado's 5.60, and Seattle's team FIP of 4.07 is also considerably lower than Colorado's 4.93, pointing to a clear gap in run prevention that favors the Mariners across the roster, not just in the starting pitching matchup.
Several injury statuses are on record for this game. Rotowire lists Tyler Bell of the Colorado Rockies with a status of 'Out.' Matt Brash, Nick Davila, and Brennen Davis of the Seattle Mariners are each listed on the 60-Day IL, while Brody Brecht and McCade Brown of the Colorado Rockies are also listed on the 60-Day IL. Taken together, the season-long figures favor Seattle, whose team ERA and FIP both outpace Colorado's by a wide margin even though the Rockies hold the better team wOBA and Sugano brings far more innings of experience to this particular start.
