Feels pretty good, don’t it? You’ve played for over twenty years, you’ve got a lifetime batting average a little higher than Cobb’s, and you’re closing in steadily on Rose’s lifetime hits mark.
But here’s your problem: while you can definitely still play at a major league level in your forties, batting around .300 even now, you also can see the day, if you keep playing at your current level or below (which is pretty likely considering your age) when your lifetime average will sink below Cobb’s lifetime average. Since you’ve been proud of keeping your average in the .370s for years, you’re certainly not going to play until it drops below .367, are you?
But you also need to keep playing, even at the .300 or below level, to accrue the hits you need to break Rose’s mark. If you quit while your average is the #1 all-time best, you’ll fall short of holding the record for most base hits. If you keep playing long enough to break Rose’s record, your average will decline to the mid-.360s. What’s your call? Which record will determine how long you keep playing?
Here’s your numbers, if you want numbers:
You’ve got 4130 h in 11222 ab = .368, as of today.
Your last three seasons’ average is .298, so if you need 127 hits to break Rose’s 4256, and you bat .298 or below, that means you’ll need 427 more at-bats at that rate to break Rose’s mark. Adding those figures to your record to date gives you a new lifetime record of 4257/11649, bringing you down to .365 lifetime. (And for you quibblers who say that “the greatest hitter in MLB history” ain’t no singles hitter, let’s assume you racked up 800-odd HRs along the way.) So, when do you hang ‘em up, before or after reaching 4257?
