Those were the rules during the Covid shortened season last year. Plus, any new pitcher that comes in has to face a minimum of 3 batters. All designed to speed up the game, which is badly needed IMO. Not sure about the runner on second to start each extra inning frame, but I'm all for trying any measure to move the games along, including a pitch clock. Get the pitcher on the rubber, get the batter in the box and let's play ball.
