Upton Keeps Producing

Justin Upton has continued his hot season by hitting another long ball yesterday. Upton's average HR is traveling 427.4 feet. Thats the longest average for any player in MLB with 5 HR's or more. His longest HR this season was his Grand Slam which traveled 461 feet. Last year he had a total of 5 HR's that went 420 feet or more. Is it time we start talking about PED's?
