The Marlins designated right-hander Elih Villanueva for assignment to create 40-man roster space for Greg Dobbs, tweets Clark Spencer of the Miami Herald. The Marlins, who finalized their deal with Dobbs earlier today, still have a full 40-man roster.
Villanueva, 25, started one game for the Marlins last year, allowing eight earned runs in three innings. He spent most of the season at Triple-A New Orleans, where he posted a 5.35 ERA with 5.7 K/9 and 3.2 BB/9 in 165 innings. The Marlins selected Villanueva in the 27th round of the 2008 draft.
