Bryce Harper wants to improve his numbers from last season, adding that he has to "step up" for the Washington Nationals.

Harper missed 62 games in 2014 because of a thumb injury.

"I have to see what [pitchers] are going to do to me, see how they approach me, really just working my pitch and not go out of my comfort zone," the 22-year-old said. "If I can do that, stay within myself and have a little bit of fun at the plate, that will go a long way."

With Adam LaRoche gone, Harper is Washington's only power threat from the left side of the plate.

"I'll help out for sure," Harper said. "After losing LaRoche, I have to step up a little bit. I have to do what I need to do. Our pitching is going to take us to the top, hopefully, but we still have to have offense. We have to do the things we need to do. I'm ready to go. I'll be feeling good."
