MLB Rules: Is This a Trip?

[ozzy6900]

As stated MLB rules, DH used, lights are on due to it being a night game and the moon is in the house of Grouch Marx. I hope that covers all the preliminaries. Oh yes, this was not my game, it was relayed to me by phone.

R3 & R2, 0 out, count on the batter is 1-1. Coach comes out of the dugout, approaches the foul line but does not cross it. He calls to F1 to put the batter on, then turns and goes back into the dugout. The caller asked if this would be considered a trip.

I thought it would be interesting what others would do here. So what do you say, is it a trip?
