Hader will earn $4.1 million rather than his $6.4 million request.
Arbitrators Mark Burstein, Dan Brent and Frederic Horowitz made the decision Friday, a day after hearing arguments.
A shaggy-haired left-hander who turns 26 in April, Hader had 37 saves in 44 chances and went 3-5 with a 2.62 ERA in his second straight All-Star season. He failed to hold a 3-1 lead in the eighth inning of the NL wild-card game, loading the bases by hitting one batter, walking another and allowing a bloop single, then giving up a two-out, bases-loaded single to Washington’s Juan Soto that scored three runs. The Nationals won 4-3 and went on to their first World Series title.
After making $687,600 last year, Hader just made the arbitration eligibility cutoff with 2 years, 115 days of major league service.
Dodgers reliever Pedro Baez has been the lone player to win.
Seven players remain scheduled for hearings, which run through Feb. 21.
