This one is going to be touch and go, as Mickey Mantle becomes just the fifth player to reach 500 career home runs. IRL, he has what's left of this year plus the next two seasons to play. With no RATH and 3-year recalc, I reckon Mick makes it to like 1970 but the slide is fairly steep, ratings wise. So if he can get 50 more by end 1968 (he got 40 IRL in '67 and '68 combined) then he just might catch Gehrig's 571. But, like I said, it'll be a close-run thing. Same goes with both Mays and Aaron. This simply isn't a high-HR save and I think you'll find the final leader will be in the 600s rather than the 700s.
