Trivino (thumb) threw off the mound on Sunday and is likely to be available in the Athletics' upcoming series against the Red Sox, Susan Slusser of the San Francisco Chronicle reports.
Trivino has battled a thumb injury for much of the past week, but he still may be able to avoid a trip to the injured list. After throwing off the mound prior to Sunday's action, he hopes to be ready to return as an option out of the bullpen for the team's upcoming series against Boston, which begins Monday.
