Mile High Mashing: Previewing the 2021 Home Run Derby
Politics aside, the biggest upside to Major League Baseball’s decision to move this year’s All-Star Game from Atlanta to Denver is that for the first time in 23 years, the Home Run Derby will be held at Coors Field, where baseballs fly further than any other major league venue due to the mile-high altitude. If you have any sustained interest in the event, this is the bucket list location for a Derby, and if that’s not enough to juice this competition, MLB has made clear the balls themselves won’t be stored in the humidor prior to the festivities, theoretically resulting in drives of even greater distance. Short story longer: MORE DINGERS!
If there’s a downside to the pending fireworks show, it’s that the new baseball MLB introduced this year isn’t carrying quite as far as years past. The average distance of a hard-hit fly ball — that is, one hit with an exit velocity of 95 mph or greater — is 366 feet, which is up five feet from the shortened 2020 season but down nine feet relative to ’19, the year those distances peaked.

That decreased distance is despite this year’s hard-hit fly balls having the highest average exit velocity of the Statcast era at 101.2 mph; they averaged 101 mph in 2019, the year that home runs peaked with an average of 1.39 per team per game. That was deemed Too Many Homers, and after dropping by 8% from 2019 to ’20, per-game home run rates have fallen another 7.85% this year, to 1.18 per team per game. The good news is that at Coors Field, that downturn won’t matter; via Statcast, this year’s hard-hit fly balls are averaging 393 feet — 7.3% further — and that’s with the humidor.
