The Orioles have signed Joel Pineiro and Mark Hendrickson to minor league contracts, according to sources.

Pineiro, 34, pitched in five games in the Orioles organization in 2012, three for the Gulf Coast League Orioles and then two at Triple-A Norfolk before season-ending shoulder surgery.

Hendrickson, 38, sat out all of the 2012 season, but he pitched for the Orioles from 2009 to 2011. He is attempting to reinvent himself as a side-armer.
