Answer
Hi Ty,

#1 If the pitcher is in the circle w/ control of the ball and R1 is stopped on 3rd and then comes off the base it is a violation of the LBR, dead ball R1 is out.

#2 a defensive player must be allowed to field the batted ball anywhere on the playing field.  Based on your facts I would have interference, dead ball runner out.  A runner must vacate any space needed for the defense to execute play.  The fact that F3 is in the "baseline" doesn't matter.
