The White Sox have designated Jeff Marquez for assignment, the team announced. The move clears a spot on the roster for Mark Teahen, who was activated from the disabled list.
Marquez, selected 41st overall by the Yankees in 2004, was called up from Triple-A Charlotte last Monday, but didn't pitch for Chicago before being designated. The 26-year-old has appeared in just one big league game, allowing a two-run home run to Yuniesky Betancourt in his lone inning of work last July. This season, Marquez has made nine starts for Charlotte, recording a 3.97 ERA.
