Bryce's recent hot streak has pushed him very close to the top of the All-Time 19 year old leaderboard for fWAR.

Note that I blue-boxed Mel Ott and Ty Cobb, because they were not rookies in their Age 19 season.
Bryce Harper needs just 0.3 fWAR to surpass Washington's own Buddy Lewis for the greatest rookie season by a 19 year old in major league history.
