Synchronicities or coincidences??  The 2018 World Series...........game 3 goes to 18 innings.......also interestingly enough.........that is TWICE a regular game....which is 9 innings......or if the home team is winning........they only play to the middle of the 9th inning....
Or was it to extend the game..........so the Networks make more off of ads........................they like to keep the game close so u don't change the channel..
