Answer to Scenario 2

If the touching by R1 is accidental, it is ignored because the batted ball has passed a fielder other than the pitcher and no other infielder has a play on the ball. Ball is in play.

If R1 intentionally deflected the batted ball, the umpire shall rule interference and declare the ball dead. R1 is declared out. The batter is credited with a base hit and is placed on first base.
