Bryce Harper finished 1-for-4 with a two-run double Wednesday, his professional debut. "I felt really good at the plate and I was not really jumpy at all. I didn't feel overmatched at all," Harper said. "They came after me and I really appreciate that. I thank all of them for coming at me and facing me with the fastball and offspeed." Harper is the second youngest player in Arizona Fall League history, four days younger than Fernando Martinez of the Mets who debuted in 2006.
