Perhaps Harper will drive in more runs. There's a good chance he'll have more opportunities with men on base as long as the rest of the Nationals lineup remains healthy. But such things are mostly out of his control.
Or perhaps Harper will steal more bases next season. He has wanted to be more active in the running game and has been eager to learn from new first-base coach Davey Lopes, who has helped engineer strong running games in the past. Lopes has encouraged Harper, who only attempted 10 steals last season, along with the rest of the Nationals to be aggressive on the basepaths.
