In 1997, Jed Hoyer was an admissions officer at Kenyon College and I was a high school senior. After he did my admissions interview for what became my alma mater, he confided that he wanted to some day get a job working in baseball. Apparently, it worked.

1/ I wanted to bring this thread to BlueSky (with some new information!) It's about the "Sockalexis Myth" that the Cleveland Guardians, formerly Cleveland Indians, were so named as an honor to former player Louis Sockalexis.
There is very little evidence for this idea.

As you might guess, while trending up is a good thing, 2% is not enough to fend off a potential price increase. So here I am asking again to help us keep our price an insanely affordable $45.95 for what you get. It's a great time to subscribe with our Midseason 50 out and the deadline coming up.

Couple years ago I wrote about how the O's had the right idea pushing the fence back, and the league as a whole should start changing dimensions all over to adjust to the kinds of athletes and analytics present in today's game, a la the NBA over its history. Vindicated by @pizzacutter4.bsky.social
