I actually have, and -- if I'm being candid -- it was in part because I had to figure out once how many words I write a year, and wondered about the hours I spent at the ballpark, traveling, etc. Just got curious. I didn't get to a real good number. But, before the pandemic, you're talking about players spending around 10 hours a day at their profession when you consider the game, treatment, prep, video, cage, bullpen, stretching, workout all of it. It wasn't unusual for a player, like say Carpenter or Molina or Fowler, to describe how they'd get a workout in before coming to the ballpark -- or early at the ballpark. And then start prepping for the game around 3ish, 4 ish. So, you've got two hours before things start at the ballpark, then an hour of treatment/maintenance, and then you've got the actual activities at the ballpark that, say, go from 2,30 to the end of the game, at 10,30. It's not unreasonable to say that's at least 10 hours a day.
And that's 162 days in the regular season. Spring days are shorter. So say five, six for the 40 days of spring and you're up to 1,840 in just sanctioned work -- some of which they're not paid for (no salaries in spring training). And we haven't even calculated the offseason workouts, the Driveline trips -- or any travel.
