Thanks to Denver’s dry and thin air, expect baseballs to fly out of Coors Field Monday during MLB’s annual Home Run Derby.

Because dry balls carry farther, baseballs at Coors Field are stored in a so-called humidor that keeps them at a steady 70 degrees and 50% humidity. But MLB announced the baseballs used in the Derby won’t be stored in the humidor, so expect some crushing blows.

Easily the most-anticipated participant is Los Angeles Angels phenom Shohei Ohtani, the first Japanese player to compete in the Derby and the first player in MLB history to be selected an All-Star as both a position player and a pitcher. Ohtani, who has 31 home runs so far this season, will face off against Washington Nationals slugger Juan Soto in the first round of tonight’s Derby.

It’ll be interesting to see if Ohtani drives more viewers. The 2019 Derby (the event was canceled last year due to the pandemic) averaged a combined 6.20 million viewers, which was down 26% from the 8.35 million who watched in 2017, according to Sports Media Watch.

For the second straight year, no Phillies players will be competing. Rhys Hoskins made it to the second round of the 2018 Home Run Derby, but lost by one home run to Washington Nationals slugger Kyle Schwarber. Two Phillies players have won the Derby — Bobby Abreu in 2005 and Ryan Howard in 2006.

Monday’s event is just the second time the Derby has taken place at Coors Field. In 1998, Ken Griffey Jr. blasted 19 home runs, barely edging out then-Cleveland Indians slugger Jim Thome’s 17 home runs.

Home Run Derby bracket

The seeding of the players in Monday’s Derby was determined by their 2021 home run totals as of Wednesday. Tiebreakers were determined by 2020 home run totals.

  • (1) Shohei Ohtani vs. (8) Juan Soto

  • (4) Salvador Perez vs. (5) Pete Alonso

  • (2) Joey Gallo vs. (7) Trevor Story

  • (3) Matt Olson vs. (6) Trey Mancini

Rules

The Derby is a single-elimination bracket event with three rounds. During the first two rounds, each batter has three minutes to belt out as many home runs as they can. During the final round, the time is reduced to two minutes per batter.

Batters are awarded 30 seconds of bonus time at the conclusion of each regulation period. A batter can earn an additional 30 seconds by belting out a home run over 475 feed during the regulation period.

Hitters are entitled to one 45-second timeout in each round, though that doesn’t extend into a batter’s bonus time.

What happens if there’s a tie?

In the event of a tie, the top two batters will faceoff in a 60-second swing-off. If a tie remains after that, hitters battle in successive three-swing swing-offs until there is a winner.

There’s only been one tie in Derby history — 2019, when Vladimir Guerrero Jr. edged out Joc Pederson in the third tiebreaker.

How much does the winner receive?

The winner of the Derby takes home $1 million, thanks to a new agreement between MLB and the MLB Players Association put in place prior to the 2019 season.
