Ohlman attended the minicamp last month in Sarasota. He noted that the move to Double-A was "quite a big adjustment." "I thought the numbers weren't quite there, but maybe I was a little unlucky, and the numbers really don't say everything," Ohlman said. "I'm the hardest on myself, harder than anybody. I'm my biggest critic. I just try to stay positive and take it day to day and see what happens, control what I can. Everything else is out of my hands. "I've got to feel that I'm better than (the pitchers) are. They can't beat me. I can't give them too much credit, but it does take a pretty big leap there. It was just another learning curve I need to go through." The Orioles selected Ohlman in the 11th round of the 2009 First-Year Player Draft out of Lakewood Ranch (Fla.) High School. They most likely would have moved him to a new position if he remained in the organization. The 40-man roster currently includes catchers Matt Wieters, Caleb Joseph and Steve Clevenger. The Orioles also will bring catchers J.P. Arencibia, Ryan Lavarnway and Brian Ward to camp.
