Maybe you remember the Pioneer League as an affiliated minor league. It was part of the MLB’s MiLB purge and is now an independent “partner” league, meaning that (like the Atlantic League), MLB can use them as an experimental lab for whatever weird rule change they want to try. The Pioneer League will be using this one: tie games will be settled by a home run derby, dubbed a “Knock Out” round. For tie games, each team designates one player each to receive 5 pitches (I presume coach or teammate pitching), and the one with the most homers wins. If still tied, two more batters are picked, etc, until the tie is broken.
I get putting a runner on second in extra innings (in the minors, don’t like it in the majors). However, I’d rather have a tie than setting a game on a gimmick like a home run derby.
