Is Johnny Damon going to get 3000 hits?
He's at 2605. He had 300 hits over the last two years (almost on the nose -- 301). So if he keeps to that pace and stays a regular this year and next, he'll be maybe 125, 150 away...he could easily get that as a scrub over a couple of years, most likely. And he's certainly not too old for that; this is his 37 year old season, so we're talking hanging on until 41 or 42. There aren't a lot of guys with Damon's overall quality who play regularly at 38, but there are some.
On the other hand: he's not really good enough any more to play every day. His OPS+ was down to 106 last year, and it's right at 100 so far this year; that's OK for a center fielder, but he hasn't been a center fielder for a good long while. Generally, the way this works is that players of Damon's quality don't wind up playing 140 games at age 38, because they're not good enough to play regularly when they've fallen that far from their peak. See: Al Oliver, or Vada Pinson (both on his most similar list). So we'll see. I'd still bet strongly against it.
How did he get this close? Two-plus seasons with the Royals when he really wasn't ready yet (that's ~320 hits through age 23). And then a whole lot of health. He's stayed over 140 games played every year so far, ages 22-36. And, well, that's about it. He's not a particularly high batting average guy (287). He takes a reasonable number of walks, so it's not as if he's getting extra ABs that way -- he already has ~170 more BB+HBP than Lou Brock.
He's obviously not HOF quality, but if he stays a regular the next two years, and if he wants to hang on after that for long enough to make it to 3000 -- well, I wouldn't vote for him, but I don't have a vote, and the actual voters may be desperate to find guys they can vote for. But as I said, my best guess is that he falls safely short of 3000, in which case he'll have no Hall support at all.
