Bryce Harper Up in 2012?? Thomas Boswell, Washington Post The Nats' decision to make a major free agent splash this winter, rather than next, is probably connected to Harper's strong showing in the Arizona Fall League. Only the rare Mickey Mantle or Ken Griffey Jr., has proved to be big league ready at age 19. But the Nats have opened the door for the possibility. Wow. I had the thought that Harper would be up in mid-2012, but this leads me to believe that he could start the season in Washington, and possibly in centerfield. I will post something on this on Minor League Ball on Sunday. http://www.washingtonpost.com/wp-dyn/content/article/2010/12/15/AR2010121506833.html
