The 26-year-old right-hander, acquired by the A's from Atlanta in the Tim Hudson trade in December, was 6-2 with a 2.75 ERA in 50 relief outings last season, when he made $370,000.
Arbitrators Jack Clarke, Janet Gaunt and Stephen Goldberg made
the decision one day after hearing the case in Tampa.
Owners have a 2-1 lead over players with two cases remaining:
Baltimore pitcher John Parrish and Cincinnati right-hander Ramon Ortiz. There will be at most five cases that go to hearings this year, equaling the low set in 1997 and matched in 2002.
