I'm trying to figure this out on gameday, what happened? 1st and 2nd one out. Batter hits pop up and infield fly rule called. Arenado falls down. Ball lands fair. Cubs runners not understanding infield fly rule take off. Arenado throws to third but fielder doesn’t realize there’s no force and just steps on bag and throws to second where fielder does same thing. So, runners are safe at second and third, but runner on second thinks he’s out and steps off and is tagged. Umps rule time was called so runner couldn’t be tagged out. So, play continues with runners on second and third and two out. Wild. Happ strikes out to end game. https://www.mlb.com/news/cardinals-win-after-infield-fly-rule-confusion
