The best way to evaluate hitters in my book is to use the advanced stat wRC+. This stat takes sOBA (weighted on base average which quantifies the value of a hitters outcome HBP to HR) and adjusts it for park effects and then puts it on a scale. A batter who has a wRC+of 100 is MLB average. This years the Nats best hitter is Anthony Rendon followed by ALR and then Jayson Werth. The interesting thing is Werth is not that far ahead of last years pace, which had him ranked 4th in MLB. Another interesting take away: based on last years stats, Jose Lobaton is probably a little underrated as a hitter by the Nats fan base. If this data was pulled yesterday Harper would have been a negative wRC+, that is BJ Upton territory.
