Chris Cotillo reported league interest in Rivera shortly after he was designated for assignment.

The Boston Red Sox are trading left-handed pitcher Eduardo Rivera to the St. Louis Cardinals, as reported by Andrew Parker of SoxProspects.com.

Boston receives right-handed pitcher Juan Garcia in the exchange. The Red Sox previously designated Rivera for assignment to clear space on their 40-man roster.

Rivera departs the Boston organization after making his Major League debut earlier in the year. He joins the St. Louis pitching staff as both teams navigate the offseason.
