Four bagger. Round tripper. Dinger. Went Deep. They’re all ways to describe the “home run”, the most popular single play in baseball. Tonight at Nationals Park in Washington D.C. we’ll see which slugger can hit the most!

Despite the fact that J.D. Martinez leads the league with 30 home runs, he won’t be participating. Too many times the participants end up messing up their swing and suffer in the second half of the season, which is why you won’t see Giancarlo Stanton, Aaron Judge or Mookie Betts.

Bryce Harper of the home town Nationals is participating, so that should be exciting!

Here is what you need to know for tonight’s competition!
