Left-hander Andrew Miller's assignment to the bullpen didn't last very long.
Called up from Class AAA New Orleans on Aug. 18 to serve as a reliever, Miller will replace injured right-hander Ricky Nolasco in the rotation starting Friday when Florida opens a three-game series against the Braves.
"I've been the long guy out of the bullpen. I'm ready for whatever they ask me to do," he said.
Miller, a disappointment for the Marlins over the last three years, spent most of the season at Class AA Jacksonville working to refine his mechanics.
He has allowed six runs (five earned) in 10 innings over three big-league games this year, including one start.
"I've certainly made progress, but by no means am I where I want to be," he said.
