Bryce Harper is confident that he can make the Nationals out of Spring Training, something manager Davey Johnson has been pushing for lately. "But I think that the main thing is ... could he handle it mentally? And I think in his mind, he's already figuring to be starting on the club, if you ask him," Johnson said. "And I haven't talked to him, but I know that he's done everything in his whole life to succeed at a higher level and compete with the best. But I think [Harper is] pretty mature. I don't look at him age-wise, as I probably should." Harper could be Washington's starting right fielder on Opening Day if they move Jayson Werth to center field. "I feel really positive about going to Spring Training this year," Harper said. "I really feel I have a legit shot at making the club. We have a lot of guys coming in -- veteran guys that could really teach me how to approach the game. ... I'm really excited for this year. "I've been working my butt off this offseason, getting ready to go out there and doing outfield stuff, working on running and jumping -- everything that consists of trying to make this team. To have Davey on my side, that a very big plus going in there."
