Runners on 1st and 2nd when a pop fly is hit to the second baseman. At this point, the umpire immediately calls "Infield Fly" and declares the batter out.
The runner on second started running to 3rd when the ball was hit and before the ball was caught.
The 2nd baseman catches the ball and immediately throws to the shortstop who tags 2nd base before the runner returns to the base.
The umpire states that all force plays are "off" when the infield fly rule is in effect and declares the runner safe at second stating he needed to be tagged out since there is no force.
Is this the correct call? I understand there in no longer a force at 3rd base since the batter is declared out but does the "all force plays are off" hold true for the runner leaving the base early on a pop fly? That seems nonsensical. What is the correct call?
