Wynns (shoulder) declined his outright assignment to Triple-A Louisville on Saturday and elected free agency.
Wynns spent the majority of last season in Triple-A, where he slashed .250/.309/.410 across 110 plate appearances. However, a teres major tear in his right shoulder cut his season short toward the end of July. It's unknown if he'll be ready for the start of spring training, but the 33-year-old backstop should be able to at least net a minor-league deal in free agency.
