The last one was over 80 years ago

It is rare but not as rare as you think.

Elly Del la Cruz hit for the cycle in 2023. I was at the game in the 80s when another Red (IIRC Ken Griffey Jr.) hit for a cycle.

The question was re: hitting for the cycle where the home run was of the inside-the-park variety.

Since inside-the-park home runs make up only a couple tenths of a percent of all home runs... that flavor of cycle is super rare.

Another way of looking at it is that failed cycles are almost always missing the triple (much less common than home runs).

it comes to a cycle.

Call it an Epicycle, or something like that.

cycle.

Trivia: what is the hardest part? The triple.

If it’s not just a hit followed by a series of errors by the opposing team, it counts as a home run.

For sure.

Even veteran catchers occasionally have gotten triples. Not often, I’ll grant you, but once in a great while.
Kyle Schwarber has even tripled!
(This year, I think)

Usually have to be fast but, with arms on MLB right fielders, it helps to have great location of the hit.
Should the ball has get away after hitting the wall or hit down the line and get to the RF corner.
The hitter is relying on a long throw & a decent time to get to the ball in the first place.
Even Mark Grace hit for the cycle, and they timed him around the bases with an hourglass. But, the triple was a hooking liner that the right fielder thought he could catch but it got past him and rolled all the way to the corner.
At Wrigley, that's a 445' throw to 3rd base. Even Grace could hit a triple in that situation!
Normally though, I agree that speed is the key.

And btw, an inside-the-park-home run is even rarer than a triple.

third baseman caught for one out, the third baseman quickly runs down and tags the runner on third who has to try to score, then the third baseman goes back to the bag for a force out on the runner advancing from second.

That's the only way I can figure it.

Is there another way?

That’s the one I saw. It was so fast nobody was sure what happened! LOL!

Runner on second had too big of lead.

I was trying to think of something with the catcher but couldn't. Not even the first baseman of the outfielders as they'd all have to throw to someone for the 3rd out.

Ever been to Cooperstown? It’s like a cathedral for BB.

Newsday, an NYC daily paper. One of the other artists told me of a 'call for entries' for an art exhibit coming up there of one's creation of a baseball card of a favorite player.

We both picked players from the New York baseball Giants. Him Bobby Thompson and me, Willie Mays.

We both got accepted, the show lasted a month so I can always say "I was in the Hall of Fame. Hah.

The place is great. My big memory is walkng in and seeing the life-sized statute of Ted Williams in his Red Sox uniform at bat at the plate.

Drove straight up the NY Trueway with my wife for three plus hours IIRC. It was a blast.

Has anyone ever “walked” into a cycle?

It was in the 1880s when walks were not only no longer a hit, but the at-bat didn't count. It was a plate appearance.
The value of walks is captured in on-base percentage, but doesn't affect batting average either way.
The answer to your question is that maybe that happened prior to 1887. But, it couldn't since then.
Oh and, HBP are treated the same as walks.
One last note: when I was a kid Billy Williams had 2 doubles, a triple and a homer in a game my parents & I went to. 11 total bases, but no cycle.
People were saying Billy should have stopped at first on the 2nd double, but I can't imagine a player's instincts would allow that. He sees a ball get to the track, he's motoring to second.

I don't know since neither is a hit, but the batter does reach first base.
