12/27/2007 - Christmas Camp and Tournament - 2007 Callahan played hard and showed good instincts. At the plate, he showed a balanced approach with good bat speed and the ability to hit the ball all over the field. Tended to have some loop in his swing, which allowed him to drive the ball at times and may work in his favor as he adds strength onto his large frame. Defensive ability at first base was solid. Worked around the ball well, and fielded it out front nicely. Also pitched, topped out around 70 mph and showed a rolling downer type breaking ball. Was around the plate mostly, and used his secondary pitches well. Likely does not have enough velocity for a future on the mound, has more value at 1B where his power may develop further.
