Well... it amounts to EXACTLY 45 degrees... which is why some (many) call it the 45 degree rule. So ... there kind of is.

My point: it's not a rule. It's an interp. That matters when somebody asks where it is in the rules.

The idea of exactly 45° is ridiculous, since nobody uses a protractor to measure.

But the line from home to the pitcher's plate and the line from the pitcher's plate to 1B are at an angle of greater than 90 degrees.

For the angle to be 90 degrees, the pitcher's plate would have to be halfway between home and 2B, directly on the 1B-3B line. But the "rubber" is a yard in front of that line.

Trig, anyone?

The second balk was a no brainer, F1 stepped toward HP while throwing to 1B.

The first balk was more nuanced. I guess I was lucky when I watched the video because I thought I saw a shoulder twitch by F1 before he started his motion to the plate the very first time I saw the video and that would be a balk.

Yes, the announcers were funny and clueless.

When I first saw this from the camera angle behind him I too thought it was an easy call.

Trig, anyone?
Distance from front-center pitcher's plate to back corner of home plate: 60' 6"
Distance from back corner of home plate to back corner of first base: 90'
Distance from front-center of pitcher's plate to back corner of first base: 63' 8 5/8"

Angle at home plate formed by foul line and line directly to center of pitcher's plate: 45 degrees
Angle formed by foul line and line from back corner of first to front center of pitcher's plate: 42.2 degrees
Angle formed by lines from front center of pitcher's plate to back corner of home plate & from front center of pitcher's plate to back corner of first base: 92.8 degrees

So I guess its more like stepping to the 46.4.

I know how to use a protractor and have used one countless times.

Uh, it's NOT EXACTLY 45 degrees. When standing on the mound, the angle between home and first is about 92.824 degrees. Halfway would be more like 46.412.

Beat ya, but you are more precise.

I had to dust off my trigonometry knowledge. It took me a while. Once upon a time, I probably could have done it in my head (save the lookup for the arctan value).

First one must have been some type of start and stop. 2nd one was pretty obvious from West's angle. Those announcers are morons. "Look at West trying to get himself into the game." West put up the stop sign, Ozzie didn't stop. What is he supposed to do?
