According to Baseball America’s Matt Eddy, the Pirates have released Aaron Poreda. Once one of the top left-handed pitching prospects in the minors, Poreda increasingly struggled with control problems and injuries. A 2007 first-round draft pick of the White Sox, he was traded to San Diego in 2009 as part of the package for Jake Peavy, then came to the Pirates in the minor league phase of the Rule 5 draft in 2011. Unfortunately, he made just three starts for Altoona in 2012 before shoulder problems shelved him for the season. In those starts he went 2-0, 2.25, but he walked 11 in just 16 innings. He was not yet eligible for minor league free agency, so he returned to minor league camp with the Pirates this year.
