Arraez asked for a raise from $2.2 million to $6.1 million, and the Marlins argued for $5 million. The case was heard by John Stout, Mark Burstein and Scott Buchheit, who are expected to issue a decision Thursday.
Arraez hit .316 with eight homers, 49 RBIs and a .795 OPS, starting 61 games at first base, 34 at designated hitter and 31 at second. The 25-year-old was traded on Jan. 20 for starting pitcher Pablo López and a pair of prosects: infielder Jose Salas and outfielder Byron Chourio.
Arraez is eligible for free agency after the 2026 season.
Seattle defeated Diego Castillo in the first salary arbitration decision this year on Wednesday, and the relief pitcher will get a raise to $2.95 million rather than his request of $3,225,000.
Twenty-three players remain scheduled for hearings, to take place through Feb. 17.
