Yes, Tris Speaker is the career record holder.  He averaged 20.4/season throughout his career.  That is amazing! 

Next up - the active player with the most career OF assists?

I would guess Mookie Betts, he's won a bunch of gold gloves.

Who has the fewest assists of any outfielder who's played at least 150 games? Two in the AL (1 each), three in the NL (2 each). All between 1960 and 2000 -- four of them in the 1990s. And one of the NL names actually led the NL in OF assists in another season.

Starling Marte is the answer to the current player with the most career OF assists (107).
