VIERA, Fla. -- The Nationals have accepted left-hander Daniel Rosenbaum back from the Rockies, per Rule 5 guidelines, the team announced on Twitter on Sunday. He will report to Minor League camp.
Rosenbaum was taken by Colorado in the Rule 5 Draft last December, and allowed four runs in eight innings without striking out a batter during Spring Training.
Two years ago, Rosenbaum was one of the Nationals' top pitching prospects, going a combined 9-6 with a 2.52 ERA for Class A Potomac and Double-A Harrisburg. He will likely start the 2013 season for Harrisburg.
