Washington Nationals at Detroit Tigers
The Nationals head to Detroit for a 6:40 PM ET start with DJ Herz listed as Washington's scheduled starter, though Rotowire also lists Herz on the 60-Day IL, which raises questions about the reliability of that scheduled assignment. Detroit is scheduled to counter with River Ryan. On the season-to-date team numbers, Washington's pitching staff carries a 4.66 ERA and a 4.77 FIP, both notably worse marks than Detroit's 3.66 ERA and 4.09 FIP, suggesting the Tigers' staff has done a better job of limiting runs overall.
Offensively the two clubs are fairly close, with Washington's WP-estimated wOBA of 0.323 slightly ahead of Detroit's 0.312, giving the Nationals a modest edge at the plate based on that figure. Still, the gap in run-prevention numbers is more pronounced than the gap in offensive output, which tilts the overall statistical picture toward Detroit. Rotowire also lists Kerry Carpenter on the 10-Day IL, Paul DeJong on the 60-Day IL, and Kyle Finnegan on the 15-Day IL for Detroit, while Washington has Tyler Baum and Connelly Early both listed on the 60-Day IL in addition to Herz.
Taken together, the figures favor Detroit, largely on the strength of the Tigers' lower ERA and FIP compared to Washington's staff numbers, even though Washington's offense grades out slightly better by wOBA. The number of injury listings on both rosters adds uncertainty to how each team's staff and lineup will actually look on the field, but based purely on the reported statistics, Detroit's run-prevention advantage stands out as the more significant separator between the two sides.
