His tenacity on the field might result in missing some time with injuries, but it also results in some monstrous home runs over the course of a season.
Let's take a look at Harper's 10 longest home runs in 2013, as noted by hittrackeronline.com.
The distances provided in the upcoming slides will be presented in "true distance", which is defined by hittrackeronline.com as being, "If the home run flew uninterrupted all the way back to field level, the actual distance the ball traveled from home plate, in feet. If the ball's flight was interrupted before returning all the way down to field level (as is usually the case), the estimated distance the ball would have traveled if its flight had continued uninterrupted all the way down to field level."
The statistic for "number of parks" is also from hittrackeronline.com and explained as being "if the ball had been struck in weather conditions of 70 degrees and no wind" with a maximum of 30 (ballparks) and a low value of zero."
