3000 career Hits for the Hammer, and the question now is,
Can he catch the Mick?
He's roughly 60 HR behind him at the moment, with Mick still likely around for two more years after this. That probably makes the final target 630-650, or 100 from where Aaron is now.
The thing against Henry in this is that the game doesn't treat early-to-mid-40s position players kindly as a rule. So I don't see Henry getting many extra seasons over his IRL, if in fact any at all.
Which means he has five seasons, tops, to overhaul the Comet. That means an average of 20 per season. From here thru end '76 IRL, Henry hit a few more than that. So the race in '75 and '76 could well prove just as nerve-racking (although thankfully without the racist overtones, hate mail and death threats) as IRL.
Keep you posted.
