MLB umpire says that you can balk with a dead ball!

[Bfair]

Let's take this play:

After a foul ball the PU has provided new ball to pitcher.
Pitcher is straddling rubber, but appears to be on the rubber to the PU---who calls play.

At the moment the PU calls play, F1 quickly turns and fires to F3 who puts tag on the runner before his return to 1B.

You are the BU...........What's your call?
Is R1 out, or do you correct PU's error of improperly putting the ball in play?
