The Astros have re-signed free agent RHP Jorge de Leon. De Leon was a shortstop in the Astros system out of the Dominican Republic for the first few years of his career until he converted to pitcher in 2010 and was eventually placed on the 40-man roster.
In 2012, the Astros used de Leon as a starter for a portion of the season, a proposition that did not go well and was eventually scrapped. De Leon was starting to regain his effectiveness late in the season after being moved back to the bullpen. He was removed from the 40-man roster after the season and became a free agent, but recently re-signed with the team he's played for since 2006.
