For one night, on one stage, in an event that showcases one signature skill, the sport without a clock embraces the entertainment of a ticking timer and the buzz of the occasional buzzer beater. The T-Mobile Home Run Derby has featured many rules iterations in its 34 years of existence, but the decision in 2015 to do away with "outs" and subject the sluggers to a time limit added a new -- and needed -- energy to the event.

That energy will be palpable at Cleveland’s Progressive Field, where the Derby, broadcast at 8 p.m. ET Monday on ESPN, will feature the A's Matt Chapman, the Mets’ Pete Alonso, the Braves’ Ronald Acuna Jr., the Blue Jays’ Vladimir Guerrero Jr., the Indians’ Carlos Santana, the Pirates’ Josh Bell, the Astros’ Alex Bregman and the Dodgers’ Joc Pederson.

In succession, Todd Frazier (2015 at Great American Ball Park), Giancarlo Stanton ('16 at Petco Park), Aaron Judge ('17 at Marlins Park) and Bryce Harper (’18 at Nationals Park) validated the tweaked Derby format with epically entertaining performances. The same format will be used this year.

So, here is a refresher course on how this Derby will go down:
How are the seeds decided?
Because defending champion Harper is not returning for the Derby and will not claim his No. 1 seed, the seeds were determined by 2019 home run totals entering Wednesday's play. Tiebreakers were determined by home run totals since June 15, as stipulated in the Collective Bargaining Agreement. Christian Yelich was the No. 1 seed due to his 31 home runs, but he's been replaced by Chapman due to injury, with Chapman slotting into the No. 1 spot.
So, the matchups are as follows:
No. 1 Chapman (21) vs. No. 8 seed Guerrero (8)
No. 2 Alonso (28) vs. No. 7 Santana (18)
No. 3 Bell (25) vs. No. 6 Acuna (20)
No. 4 Bregman (22) vs. No. 5 Pederson (20)
What is the format?
It's a single-elimination bracket system with three rounds total. In each bracket, the higher seed hits second.
Batters will have four minutes per round. The clock starts with the release of the first pitch. Interestingly, when the new format was created in 2015, batters were supposed to have five minutes per round. With rain in the forecast in Cincinnati that night, the decision was made to shorten the rounds to four minutes. The event went so well that MLB opted to keep the four-minute rounds in effect.
It should be noted that once the second player in a given round exceeds the home run total of his opponent, the round ends. There is no need for a player to add to his tally.
After the first round, the winner of the Chapman-Guerrero matchup will meet the winner of Bregman-Pederson. On the other side of the bracket, the Alonso-Santana winner faces the Bell-Acuna winner. The two players left standing will meet in the final round.
Can players stop the clock?
Yes. In the first round and semifinals, each batter is entitled to one 45-second timeout. In the finals, each batter gets two timeouts -- one for 45 seconds and another for 30 seconds.
In the 2015 semifinals against Josh Donaldson, Frazier took his timeout with one minute, 49 seconds remaining in the round while trailing, 9-6. He regrouped and wound up tying Donaldson with less than 10 seconds left before drilling a 444-foot blast just as time expired to advance to the finals against Pederson.
The timeout wound up working against Frazier a year later, because after Stanton hit just six homers in the first 1:35 of the finals, he took a timeout, then pounded out 14 more following the breather to take the title away from the Toddfather.
Having the second timeout in the finals proved huge for Harper last year. Trailing Kyle Schwarber, 18-9, with just 1:20 left on the clock, he used his second timeout to regroup and then went on a frenzy to wow the Nationals Park crowd.
Can participants earn bonus time?
Yes, 30 seconds of bonus time will be awarded for hitting at least two home runs that each equal or exceed 440 feet. Distances will be tracked and posted using Statcast. Any bonus time will be awarded at the end of the initial four-minute round and the timer will not stop during the bonus time period.
Last year, Harper’s 18th homer of the finals cleared the wall just as his “regulation” time expired. That tied him with Schwarber. But because he had earned the 30-second bonus, he was able to hit the winning blast in “overtime.”
How are ties broken?
Ties in any round will be broken by a 60-second swing-off with no stoppage of time or additional time added. If a tie remains after the swing-off, batters will engage in successive three-swing swing-offs until there is a winner.
There has not yet been a swing-off under the new format since it was installed in 2015.
Is money on the line in the Derby?
Yes, and more than ever. As part of a multifaceted new agreement between MLB and the MLB Players Association prior to the 2019 season, the Home Run Derby prize pool was increased from $725,000 to $2.5 million. The winner takes home a cool $1 million of that total.
