The interesting story of Adam Greenberg possibly playing for the Orioles came to an end this morning when the club released the 32-year-old outfielder. He had been signed as a minor league free agent on Dec. 22. Greenberg's emotional story led to him getting a one-day contract and one big league at-bat with the Miami Marlins last Oct. 2. An online petition led to the move for Greenberg, who had first made the majors in 2005 with the Cubs, but got hit in the head with a 92-mph fastball on the first pitch he saw in the majors. It took him seven years and that one at-bat to get back and it was quite the comeback story. But the story won't continue with the Orioles. Greenberg was originally drafted by the Cubs in the ninth round out of North Carolina in 2002. He had played mostly in independent ball since 2008. Greenberg struck out on three pitches against the Mets' R.A. Dickey in his comeback at-bat. His one-day contract was worth $2,623, which was donated to an organization that researches brain trauma in athletes.
