Nate Robertson, most famous in St. Louis Cardinals circles for losing game three of the 2006 World Series against Chris Carpenter, has joined AAA Memphis as a minor league free agent, according to the Cardinals' official website. 

Robertson has spent his entire Major League career as a starter, but his significant platoon splits and the Cardinals' current struggles with their left-handed specialists suggest his place in the Cardinals' future would be in relief if it's anywhere at all. Since 2007 Robertson's 13-22 with an ERA of 5.93. His best season was 2006, when he went 13-13 with an ERA of 3.84.
