Among the erratic statistics that "The Shredder" reveals is Upton's fluctuating slugging percentages during his career and the marked difference in his home and road splits. In discussing his positives however, Kenny notes that Justin Upton is one of only nine players in the past four decades to slug over .520 twice before the age of 23. Will he get the chance to do so again for the Diamondbacks? We'll have to wait and see. But it's certainly a reasonable aspect to mention how much he enjoys hitting at Chase Field. His line away from Chase is.250/.325/.406, a .731 OPS that's over two hundred points lower than what he hits at home.
