On Monday, the St. Louis Cardinals released struggling relief pitcher J.C. Romero and promoted right-handed reliever Eduardo Sanchez from Triple-A Memphis, according to the team's official Twitter feed. Romero struggled in 8.0 innings with the Cardinals this season, producing an alarming 10.13 ERA and a paltry 5.6 strikeouts per nine innings, and the team granted the 35-year-old lefty his unconditional release as a result. The Cardinals now have just one left-handed reliever in the bullpen -- Marc Rzepczynski -- but as Derrick Goold of the St. Louis Post-Disptach points out, perhaps Mike Matheny will look to Kyle McCellan for help.

As for Eduardo Sanchez, the 23-year-old pitched 13.1 innings at Triple-A Memphis in 2012, recording a 6.08 ERA to go with 13 strikeouts and 10 walks.
