News: Whelan signed a minor league contract with the Athletics on Saturday, Matt Eddy of Baseball America reports.
Impact: Whelan pitched in one game with the Tigers last season, allowing two runs on three hits over 1.1 innings. He spent most of the season with Triple-A Toledo, where he put up some good numbers -- 2.70 ERA and 1.18 WHIP over 43.1 innings -- but he was also used as a closer and converted 20 saves. The contract could include an invite to spring training, but the report doesn't indicate whether or not that is the case.
