Baseball Question: Would This be a Home Run?

Nope, I’m thinking of the “Definitions” section of Law 19 which states:

So, if you kick the ball and I catch it with one foot in touch, I get to throw the lineout.

Thirty years ago, outfielders in Yankee Stadium had to deal with three monuments within the field of play.

The ump is “part of the field”. Umpires work field mechanics constantly so that they can get into the best position to see the play and make the call without getting into the action proper. However, occasionally an umpire will get hit. If it was a thrown ball, the ball is in play. If it was a batted ball that has passed by a defensive player, or been touched by a defensive player, it’s in play. If it hasn’t passed a defensive player, the ball is dead, and the batter and all runners are awarded one base.
