As MLBTR's Luke Adams pointed when the A's designated Gaudin for assignment, the righty had good strikeout and walk rates this year (10.4 K/9 and 2.6 BB/9), but was hit hard and posted an ERA of 8.83. The A's designated Ramirez for assignment after a seven game stint in which he walked as many batters as he struck out (ten).
The 27-year-old Gaudin was effective as recently as last season. His hit and homer rates are considerably higher than usual this year, but some pitching-starved team may sign him. Jon Paul Morosi of FOX Sports says (via Twitter) that he thinks Gaudin will attract interest.
