Washington Nationals vs Miami Marlins Prediction, Odds and Picks for Today, 09/09/25

Expect runs between the Miami Marlins and the Washington Nationals as these teams square off Tuesday evening. Monday’s matchup between the teams resulted in 22 combined runs with Cade Cavalli and Janson Junk starting for their respective clubs, and I favor the over once again the following day. Mitchell Parker is set to start this game for the Nationals, entering play with a 5.87 ERA. The southpaw starter has been in horrific form of late, and he just faced this Marlins lineup in his last start, failing to reach 5 innings of work. I expect a strong offensive output from the Miami bats in this spot.

Adam Mazur has made 3 starts this season for the Marlins, allowing 10 earned runs with an additional unearned run surrendered in his 15.2 innings of work so far. Mazur faced this Washington Nationals lineup in his last outing, just a week ago, and he allowed 4 earned runs with an additional unearned run across 6 innings of work. The right-hander allowed 10 hits in that game and now with increased familiarity I’d expect the Nationals to find offensive success.
