Every month I track the distances for as many home runs as I can on the farm. You can see the latest version, which looks at the second half of July by clicking here. I use trackman data when available, and video when it’s not (and the video IS available). In total this season I’ve gotten distances on 335 home runs on the farm system this year. There have been 443 home runs hit this season. So, there’s certainly some missing data, but most of it is there.
The longest home run of the year so far goes to catcher/first baseman Pabel Manzanero at 467 feet.
