Bryce Harper has had a tremendous first half to his rookie season, as he has helped the Washington Nationals stay atop the NL East through 77 games. The Nationals have relied heavily on their rookie phenom, who has been pivotal to the Nats' success after they were overcome with injuries to key offensive producers like Ryan Zimmerman, Jayson Werth and slugger Michael Morse.
While in the lineup for 30 of the Nats' wins, Harper has hit .328. In the 26 losses since joining the team, he's gone a .214 clip. That is just one of several areas where he needs to find consistency going into the season's second half.
If he can fix the following holes in his game, it will help the Nationals bring their first division title, and perhaps more, to D.C.
