Brach was awarded $3.05 million instead of the team's offer of $2,525,000 by arbitrators Edna Francis, Robert Herzog and Sylvia Skratek. The panel issued its decision, Friday, a day after hearing arguments.
A right-hander who turns 31 in April, Brach was 10-4 with a 2.05 ERA in a career-high 71 appearances last year and made $1.3 million. He struck out 92, also a career best, in 79 innings and had two saves.
Baltimore had not lost since its case against pitcher Ben McDonald in 1995. Orioles backup catcher Caleb Joseph lost his case this month and will get $700,000 rather than his $1 million request.
Players and teams have split 14 decisions this offseason. New York Yankees reliever Dellin Betances was the final case Friday, and the 15 hearings are the most since clubs won 10 of 16 decisions in 1994.
