Miami Marlins at Arizona Diamondbacks
The Marlins visit the Diamondbacks with a pitching matchup that leans toward Arizona on paper. Michael Soroka has worked approximately 99.3 innings with a 3.53 ERA and a 3.11 FIP, both markedly better run-prevention marks than Janson Junk's 4.54 ERA and 4.28 FIP across roughly 111.0 innings for Miami. Soroka's numbers suggest more consistent missed-barrel outcomes this season, while Junk has logged the heavier workload but with less favorable results.
Offensively, the two clubs are close. Miami carries a WP-estimated wOBA of 0.318 against Arizona's 0.310, giving the Marlins a slight edge in overall offensive output. On the run-prevention side for the teams as a whole, Arizona's ERA of 4.11 is a touch better than Miami's 4.13, though Miami's team FIP of 4.23 is better than Arizona's 4.38, muddying which staff has been the stronger unit beyond the starters themselves.
Both rosters carry notable injury statuses. Kyle Amendt and Ryan Bruno are each listed on the 60-Day IL for Arizona, while Yordin Chalas is listed on the 7-Day IL for the Diamondbacks. Miami's list includes Aiva Arquette on the 7-Day IL, Anthony Bender on the 15-Day IL, and Keyner Benitez on the 60-Day IL. Taken together, the individual pitching matchup and Soroka's superior ERA and FIP figures give Arizona the more favorable set of numbers heading into this one, even with Miami's slightly better team wOBA and FIP.
