I'll leave this right here...
Starting extra innings with a runner on second has had large ramifications to date. In 2019, baseball saw 37 games go 13 innings or longer, with eight over 15 innings. Last year, there were only 11 games that lasted 13 innings or longer, and none over 15. The idea behind reducing marathon games might be that, with pitching staffs built with more and more one-inning pitchers over time, and injuries continuing to stay prevalent, putting pressure on the game to end quicker could be good for arms on every team.
Certainly, everyone working at the game appreciates avoiding 20-inning marathons. But those attending the game might disagree, and cite the fact that, with this rule in place, extra-inning runs have scored at over two times the rate they score in the first nine innings. That’s fundamentally different baseball! Their retort might ask baseball teams to build their rosters with more pitchers capable of going longer in emergency situations. — Sarris
