Adams was optioned to Triple-A Columbus on Saturday, Paul Hoynes of the Cleveland Plain Dealer reports.
The Indians announced Saturday that Joba Chamberlain will make the Opening Day roster, which may have been what took Adams out of the equation. Adams has been effective this spring, striking out nine batters in 10.1 innings, but he'll start the season in Columbus. If one of the Indians' relievers struggles early this year, Adams would be a candidate for a call-up given he made 28 appearances at the big league level last year.
